p. 237
Jasvin Singh, Subramani Parasuraman, Sathasivam Kathiresan
DOI
:10.4103/pr.pr_162_17
Background:
Cinnamomum cassia
or
Chinese cinnamon
is one of the fundamental herbs in traditional Chinese medicine.
C. cassia
is used as astringent, antiseptic, and used for the treatment of metabolic disorders. The antioxidant and antidiabetic effects of its extracts are unclear. Hence, the present study is planned to investigate the antioxidant and antidiabetic effects of methanolic extracts barks of C. cassia.
Materials and Methods:
Bark of C. cassia was extracted with methanol, ethanol, and acetone and its antioxidant activity was studied using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) free radical scavenging assays. Acute toxic effect of methanolic extract of
C. cassia
(MECC) carried out as Organisation for Economic Co-operation and Development guidelines. MECC was studied for its antidiabetic effect using streptozotocin (STZ)-induced diabetic rats.
Results:
In both DPPH and ABTS free radical scavenging assay, methanolic and ethanolic extracts exhibited free radical scavenging activity. In acute toxicity testing, MECC did not show any significant toxic signs up to 2000 mg/kg, hence the antidiabetic activity of MECC was carried out at the dose levels of 125, 250, and 500 mg/kg. MECC showed antidiabetic activity from 2
nd
week of the experiment onward. At the end of the study, diabetic animals showed significant increases in the levels of total cholesterol (TC), very-low-density lipoprotein, and TC/high-density lipoprotein radio compare with that of normal control and MECC prevented the STZ-induced hyperlipidemia. In the histopathological analysis, sections from the liver, pancreas, and kidney of the diabetic animals and the animals treated with MECC 500 mg/kg showed mid-to-moderate toxic effects.
Conclusion:
The MECC exhibited significant antioxidant and antidiabetic activities.

Beneficial effects of
Caesalpinia digyna
extract against acid aspiration-Induced acute lung injury in mice
p. 243
Manju Chaudhary, Pratibha Sharma, Meenu Mittal, Rajneet Kaur, Vivek Dharwal, Ashwani Kumar, Amarjit Singh Naura
DOI
:10.4103/pr.pr_4_18
Objective:
Caesalpinia digyna
belongs to the genus
Caesalpinia
, which is known since ancient times for its medicinal properties. The present work was designed to evaluate the beneficial potential of hydroalcoholic extract of the roots of
C. dignea
against hydrochloric acid (HCl)-induced acute lung injury in mice.
Materials and Methods:
Ethanolic extract of
C. dignea
roots at a dose of 50, 100, or 200 mg/kg boy weight was given once orally 90 min before HCl administration. Mice were then analyzed for infiltration of inflammatory cells in bronchoalveolar lavage fluid (BALF) and oxidative stress markers in the lung tissue. Further, the effects of the extract were compared with bergenin isolated from the extract.
Results:
Our results showed that an oral administration of the extract 90 min before HCl instillation reduced the infiltration of neutrophils in the lungs in a dose-dependent manner. Reduction in lung inflammation was associated with decline in pulmonary edema as the total protein content in the BALF was found to be decreased substantially. The drug also restored the redox balance in the lungs toward normal on HCl treatment as assessed by measuring the levels of reactive oxygen species (ROS), malondialdehyde (MDA), glutathione (GSH), and catalase activity. Bergenin, isolated from the plant, was able to suppress the neutrophils but increased the macrophage number in BALF when administered before HCl instillation, suggesting immunoregulatory properties of the key constituent of the extract.
Conclusion:
Our data suggest that hydroalcoholic extract of
Caesalpinia digyna
roots constitute the phytochemicals that can protect against HCl-induced acute lung injury in mice.

p. 250
Jeffrey Pradeep Raj, John Michael D'Cruz, Tomson Toms, Pradhyumna Muralidharan, Mangala Rao
DOI
:10.4103/pr.pr_153_17
Background:
Withania somnifera
(WS), Indian ginseng/ashwagandha, is a common household plant. Its commercially available aqueous or ethanolic root powder extract containing the active substance withanolides is known to enhance physical endurance (stamina). The potency of crude root powders, especially post-extraction, is unknown.
Objectives:
The aim of this study was to compare the efficacy of crude root powder of WS post-extraction with commercial root preparation in enhancing the physical endurance of mice using forced swim endurance model.
Materials and Methods:
Male Swiss albino mice, 6–8 weeks old with mean (standard deviation) weight of 35.17 (3.36) g, were randomized into three groups of six animals each: control – carboxymethyl cellulose 0.5%, standard – commercial root preparation of WS (100 mg/kg), and test – crude root powder post-extraction (100 mg/kg). Drugs were administered per oral, once daily, for 7 days. On the 8
th
day, animals were allowed to swim till exhaustion in a propylene tub of dimension 25 cm radius and 30 cm height, with water level at 15 cm. The end point of swim endurance was when the mice near drowned.
Results:
There was no significant difference in body weight of mice between groups. One-way ANOVA between groups for drowning time was significant (F[2,15] = 12.771,
P
= 0.001). Tukey's
post hoc
test was significant for test versus control (
P
< 0.001) and standard versus control (
P
= 0.047). However, test versus standard was not statistically significant (
P
= 0.069).
Conclusion:
Hence, we conclude that crude root powder of WS after extraction also possesses physical endurance enhancing property and may be used to enhance the stamina.

DOI
:10.4103/pr.pr_114_17
Background:
One of the major antioxidants in
Myrmecodia pendens
(sarang semut) tubers is anthocyanin.
Objective:
To obtain antioxidant activity and anthocyanin concentration from sarang semut optimally through an appropriate method.
Materials and Methods:
Microwave-assisted extraction (MAE) was chosen because of its brief extraction time (ET), saving solvents, and being inexpensive compared to conventional extraction methods. Experiment design was prepared using response surface methodology. 1,1-diphenyl-1-2-picrylhydrazyl and reducing power method were used for the determination of the antioxidant activity, while the Association of Analytical Communities official method 2005.02 was used for the anthocyanin concentration calculation.
Results:
It was found that the optimum antioxidant activity was obtained at 80% ethanol, sample-to-solvent ratio (S/S ratio) 1:12, ET 10 min, and MAE power 50%. Meanwhile, the optimum anthocyanin extraction was obtained at 80% ethanol, S/S ratio 1:8, ET 3 min, and MAE 10%.
Conclusion:
The optimum condition of antioxidant activity and anthocyanin concentration was the same at the solvent used, yet different at the S/S ratio, ET, and power level which open further research to support this study.
Abbreviations Used:
S/S ratio: Sample-to-solvent ratio, ET: Extraction time, MAE power: Microwave-assisted extraction power, RSM: Response surface methodology.

Background:
Momordica charantia (Cucurbitaceae)
is a plant, reported for its variety of ethnic medicinal uses and widely grown in Asia, Africa, and the Caribbean for its edible fruit.
Objective:
The present work has been planned to screen antiarthritic activity of fruit of the plant with the ethanolic and aqueous extracts.
Materials and Methods:
Fruit powder was successively extracted with ethanol (95%) and water using soxhlet extraction and subjected to phytochemical screening to identify different phytoconstituents. Ld
50
studies for both (ethanolic and aqueous) extracts were conducted up to the dose level of 2 g/kg by following OECD up and down method of guidelines No. 425. Antiarthritic activity was performed using formaldehyde, Freund's adjuvant-induced arthritis in rats, and Collagen-induced arthritis model in mice. Statistical analysis was performed using one-way analysis of variance followed by Dunnett's
t
-test.
P
< 0.05 was considered statistically significant.
Results:
Preliminary phytochemical studies revealed the presence of saponins, sterols, mucilage, glycosides, alkaloids, steroidal saponins in both the ethanolic and aqueous extracts of
M. charantia
. No mortality was observed with aqueous and ethanolic extracts up to the maximum dose level of 2 g/kg. In Formaldehyde induced arthritis model the percentage reduction in paw volume was 30.69% and 42.81% for aqueous extract whereas for ethanolic extract it was 25.23% and 39.5%. In Freund's adjuvant model, the percentage of reduction in paw volume was 56.1% and 66.51% for ethanolic extract and 52.6% and 63.83% for aqueous extract, respectively. In collagen-induced arthritis models, the arthritis index was found 6.02 and 3.68 for ethanolic extract at medium and high dosage. The arthritis index of aqueous extract was found 5.66 and 4.03 at medium and high dosage.
Conclusion:
From the present experimental findings of both pharmacological and biochemical parameters observed from the current investigation, it is concluded that at the doses of 200 and 400 mg/kg aqueous extract of
M. charantia
possesses potentially useful anti-arthritic activity since it gives a positive result in controlling inflammation in adjuvant-induced arthritic and collagen-induced arthritis model in rats and mice

p. 275
Ramesh Parjapath, Veeresh Kumar Sali, Sangeetha M Kannan, Atmaja Kurapati, Hannah Rachel Vasanthi
DOI
:10.4103/pr.pr_115_17
Background:
Increase in obesity incidence has become serious threat to civilized human population. Traditional Indian System of Medicines may have many potential leads in managing obesity. (-)-Hydroxycitric acid (HCA), a unique compound which is present in
Garcinia
species, has been safely used for centuries in Southeastern Asia for various purposes.
Objective:
To determine the effect of HCA treatment on peroxisome proliferator-activated receptors (PPARs) and their target genes.
Materials and Methods:
Effect of the calcium salt of HCA on adipogenic transcription factors PPARs and their target genes (lipoprotein lipase, fatty acid synthase, fatty acid binding protein, glucose transporter 4, and adiponectin) during adipogenesis in 3T3-L1 was investigated. The extent of adipogenesis was checked by measuring the lipid accumulation and glucose uptake in the presence and absence of HCA.
Results:
HCA treatment modulated the differentiation of adipocytes in a dose-dependent manner, wherein lower concentrations showed increased accumulation of lipid depots. HCA treatment increased PPARγ and its target genes during adipocyte differentiation, which emphasize the role of HCA in adipocity and obesity. Moreover, the binding conformations of HCA and PPARα and PPARγ were predicted using flexible docking and confirmed with known agonists, which also confirms the bioactivity.
Conclusion:
HCA decreases circulating lipids through raised levels of adipogenic-specific genes activated by the PPARs, thereby augmenting adiposity and related complications.

Syed Imran Bukhari, Inshah Din, Simmi Grewal, Manoj Kumar Dhar
DOI
:10.4103/pr.pr_124_17
Background:
Use of herbs as medicinal plants to treat various clinical ailments has grown for the last two decades. Cancer is one of the most dreadful disease and extracts of various medicinal herbs have been subjected for the analysis to elucidate their possible role in the prevention of proliferation of cancer cells. Crocus sativus is an autumnally flowering plant rich in active ingredients apocarotenoids such as crocin, picrocrocin, and safranal which have been reported to have antiproliferative potential due to their strong antioxidant potential.
Objective:
To elucidate the antiproliferative potential of C. sativus extract (CSE) and its major constituents crocin and safranal on four different malignant cell lines (Alveolar lung epithelial cancerous cell line [A549], breast epithelial cancerous cell line [T47D], colon colorectal cell line [HCT-116], and prostrate cancerous cell line [PC3]) and nonmalignant cell line (L929).
Materials and Methods:
High-performance liquid chromatography was used to measure the content of crocin and safranal in saffron extract and antiproliferative effects of CSE, crocin, and safranal were evaluated by 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. All cells were incubated with different concentrations of CSE, crocin, and safranal for 48 h. In a concentration-dependent manner, both safranal and crocin reduced cell proliferation in all malignant cell lines.
Results:
The IC50 values ranged between 0.32 and 0.42 mM for safranal, 0.31 and 0.92 mM for crocin, and 0.58 and 0.98 mg/ml for saffron extract.
Conclusion:
Based on these findings, it can be concluded that saffron and its components can inhibit cell proliferation in cancerous cells. Consequently, these agents could potentially be used as a chemopreventive agent for cancer management in the near future.

DOI
:10.4103/pr.pr_159_17
Background:
Methotrexate (MTX) is used for numerous malignancies and autoimmune disorders. With such widespread use, MTX-induced hepatorenal toxicity is an issue of concern that still needs to be addressed.
Objective:
The aim of the present study is to evaluate the role of
Terminalia bellerica
extract (TBE) in MTX-induced hepatorenal toxicity in Wistar albino rats.
Materials and Methods:
Rats were randomly divided into six groups (
n
= 6) – received MTX 20 mg/kg intraperitoneally on the 4
th
day along with pretreatment with different doses of TBE (100 mg/kg, 200 mg/kg, and 400 mg/kg, p.o) given from 1
st
to 15
th
day. MTX-induced hepatorenal toxicity was evaluated by biochemical hepatic and renal parameters along with histopathology and immunohistochemistry.
Results:
Hepatorenal toxicity induced by MTX was attributed to increased oxidative stress, biochemical liver, and kidney parameters and upregulation of caspase-3 and nuclear factor kappa B (NFkB). MTX-treated group observed twofold to threefold rise in aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN), and creatinine values–138.49 IU/L, 125.81 IU/L, 63.09 mg/dl, and 1.895 mg/dl, respectively. Groups pretreated with TBE (400 mg/kg) observed a significant decrease (
P
< 0.001) in oxidative stress and biochemical parameters – AST (63.94 IU/L), ALT (55.98 IU/L), BUN (37.02 mg/dl), and creatinine (1.065 mg/dl). Pretreatment with TBE 400 mg/kg, histopathology of both liver and kidney tissues showed improved architectural damage and immunohistochemistry showed downregulation of increased antigens-caspase-3 and NFkB.
Conclusion:
T. bellerica
fruit extract (400 mg/kg) showed significant hepatorenal protection by reducing oxidative stress, elevating serum enzymes, and downregulating the tissue expressions of caspase-3 and NFkB.

Background:
Sexual dysfunction is caused by multiple anatomical, physiological, medical, and psychological factors. Many studies have shown the efficacy of herbal remedies on increasing libido and sexual function. This study aimed to evaluate and compare the effects of three herbs of ginger, cinnamon, and rose on sexual function of depressed women with low sex drive.
Materials and Methods:
This randomized double-blinded clinical trial was conducted on 140 depressed women with sexual dysfunction who were divided into four groups receiving oral drops of rose, ginger, cinnamon, or placebo. The information about the two variables of sexual function and depression were collected by Female Sexual Function inventory questionnaire and Beck Depression Inventory, respectively. Data were analyzed using Chi-square, Wilcoxon signed-rank test, Kruskal–Wallis test, and Pearson correlation coefficient.
Results:
The mean scores of sexual dysfunction and depression were significantly improved in the three groups after treatment (
P
< 0.05) so that sexual dysfunction score in placebo group had the lowest rate of improvement with the mean of 1.55 ± 0.44 and in ginger group had the highest improvement rate with the mean of 4.04 ± 1.07. Depression in placebo group had the lowest improvement rate with the mean of 3.71 ± 1.94 and in cinnamon group had the highest rate of improvement with the mean of 6.29 ± 1.57, but there was no significant difference between the four groups (
P
> 0.05). The factors such as received treatments with impact factor of 0.723 and age with impact factor of 0.170 had direct relation and depression with impact factor of −0.078 had reverse relation to sexual performance improvement (
P
< 0.05).
Conclusion:
Herbal medicines, except for their positive impacts on sexual function, may have positive but minor effects on depression.

In vitro
investigation effects of 4-Hydroxyacetophenone on rat thoracic aorta's vasomotor activity
p. 319

Background:
Z. clinopodioides Lam
. is also known as a ''Field Mint'' Seven compounds which have vasodilator activity have been isolated from Z. clinopodioides Lam. and two of them are phenolics compounds and these are acetovanillone, 4-HAP, four of them are flavonoids and these are acacetin, apigenin, chrysin, thymonin, one derivat of cinnamic acid and ethyl 4-coumarate.
Objective:
In this study, it was aimed that was defined vasodilator activiy mechanisms of fenolic compound 4-HAP on isolated rat thorasic aorta.
Material and Method:
In this study 40 male adult Sprague Dawley rats were used. Prepared rings were laid out into the 20 ml organ bath with Krebs solution. Rings were stretched by 1g and they were subjected to 1 hour incubation period. In the end of the incubation period, PE, KCI, nifedipine, L-NAME, 4-HAP, SQ22.536, ODQ, ACh, SKF96365, Propranolol, Atropin, TEA, Gibenclamide, 4-aminopyridine and U73122 were implemented to bath with a protocol.
Results:
Mechanisms of relaxed effect the of 4-HAP were assigned by using antagonists. It was observed that vasorelaksan effect of 4-HAP on endothelilal aorta smooth muscle contractions which had been inductioned by PE under the existance of L-NAME was considerably inhibited.
Conclusion:
It was stated that 4-HAP relaxed PE and KCI contractions and owing to this activity endothel intact tissues on L-NAME existance notably decreased because of NO pathyway. It is firmly believed that as relaxed effect of 4-HAP declines remarkably under the existance of 4-aminopyridine and nifedipine on endothel denuded aorta rings, activity could be on K
+
channel and L-type Ca
+2
channel.
Abbreviations Used:
4-HAP: 4-hydroxyacetophenone, SQ22536: 9-(Tetrahydro-2-furanyl)-9H-purin-6-amine, 9-THF-Ade, L-NAME: N (omega)-nitro-L-arginine methyl ester, DMSO: Dimethyl sulfoxide, 4-AP: 4-aminopyridine, TEA: Tetraethylammonium, ODQ: 1H-(1,2,4) oxadiazolo(4,3-a)quinoxalin-1-one, SKF96365: 1-[β-(3-(4-Methoxyphenyl)propoxy)-4-methoxyphenethyl] 1H-imidazolehydrochloride, 1-[2-(4-Methoxyphenyl)-2-[3-propoxy]ethyl]imidazole, U73122: 1-[6-[((17β)-3-Methoxyestra-1,3,5[10]-trien-17-yl)amino]hexyl]-1H-pyrrole-2,5-dione, ACh: Acetylcholine, KCI: Potassium chloride, IP3: Inositol triphosphate, DAG: Diacylglycerol.

Background:
Combretum hypopilinum is used in Togolese traditional medicine to alleviate various ailments including hepatic disorders.
Objective:
This study evaluates the hepatoprotective activities of crude ethanolic extract of C. hypopilinum root bark (CECH) and its possible mechanism(s) of action in Wistar rats.
Materials and methods:
In vitro antioxidant potential was evaluated using DPPH, Ferric-reducing power and hydroxyl radical scavenging assays. Hepatoprotective activity was assessed using CCl4-induced acute hepatotoxicity in rats. Animals were pretreated orally with different doses of CECH (200 and 400 mg/kg) once daily for 7 consecutive days and were subjected to intraperitoneal single injection of CCl4 (1 mL/kg). Serum markers of hepatic damage, hepatic endogenous antioxidants, NO, TNF-α and lipid peroxidation contents were measured out.
Results:
The pretreatment with CECH significantly decreased levels of hepatic enzymes (p < 0.05, p < 0.01, p < 0.001) and MDA in pretreated rats (p < 0.05, p < 0.01). CECH restored the decreased levels of hepatic antioxidants including SOD (p < 0.01), CAT (p < 0.05 at 400 mg/kg) and GSH (p < 0.05 at 400 mg/kg) and significantly inhibited hepatic production of NO (p < 0.05, p < 0.01).as well as the level of TNF-α (p < 0.001) in pretreated rats. Protective effects of CECH were confirmed by histopathological examinations. CECH exhibited antioxidant in vitro and contains also total phenol and flavonoid.
Conclusion:
This study suggests that CECH protected the liver from CCl4-induced hepatic damage possibly via antioxidant and anti-inflammatory mechanisms.
Abbreviations Used:
CECH: Crude ethanolic extract of combretum hypopilinum root bark, CCl4: Carbon tetrachloride, DPPH: 2,2-Diphenyl-1-picrylhydrazyl, AlCl3: Aluminum chloride, ALT: Alanine aminotransferase, AST: Aspartate aminotransferase, LDH: Lactate dehydrogenase, ALP: Alkaline phosphatase, TC: Total cholesterol, TG: Triglycerides, TB: Total bilirubin, TP: Total protein, MDA: Malondialdehyde, SOD: Superoxide dismutase, CAT: Catalase, GSH: Glutathione, NO: Nitric oxide.
