Yumi Zuhanis Has-Yun Hashim, Abbas Phirdaous, Amid Azura
July-September 2014, 6(3):191-194
DOI:10.4103/0974-8490.132593  PMID:25002797
Background: Agarwood is a priceless non-timber forest product from Aquilaria species belonging to the Thymelaeaceae family. As a result of a defence mechanism to fend off pathogens, Aquilaria species develop agarwood or resin which can be used for incense, perfumery, and traditional medicines. Evidences from ethnopharmacological practices showed that Aquilaria spp. have been traditionally used in the Ayurvedic practice and Chinese medicine to treat various diseases particularly the inflammatory-associated diseases. There have been no reports on traditional use of agarwood towards cancer treatment. However, this is most probably due to the fact that cancer nomenclature is used in modern medicine to describe the diseases associated with unregulated cell growth in which inflammation and body pain are involved. Objective: The aim of this current study was therefore to investigate the potential anticancer properties of agarwood essential oil obtained from distillation of agarwood (resin) towards MCF-7 breast cancer cells. Materials and Methods: The essential oil was subjected to screening assays namely cell viability, cell attachment and sulforhodamine B (SRB)-based cytotoxicity assay to determine the IC 50 value. Results: The agarwood essential oil caused reduction of the cell number in both the cell viability and attachment assay suggesting a cumulative effect of the cell killing, inhibition of the cell attachment and or causing cells to detach. The agarwood essential oil showed IC 50 value of 900 μg/ml towards the cancer cells. Conclusion: The agarwood essential oil exhibited anticancer activity which supports the traditional use against the inflammatory-associated diseases. This warrants further investigation towards the development of alternative remedy towards cancer.

July-September 2014, 6(3):218-226
DOI:10.4103/0974-8490.132599  PMID:25002802
Background: Citrullus colocynthis is a folk medicinal plan of United Arab Emirates. Several studies on this plant reported and focused on the biological and toxicological profile of fruits pulp. The present study focused on the antioxidant potency of leaf extract of this plant. Aim: To evaluate the antioxidant and xanthine oxidase (XO) inhibitory activities of C. colocynthis by chemical method. Materials and Methods: Four different solvent extracts (methanol-CCM, methanol: water (1:1)-CCMW, chloroform-CCC and hexane-CCH) of leaves of C. colocynthis were investigated for their free radical scavenging activity using DPPH radical as a substrate, lipid peroxidation (LPO) inhibitory activity using a model system consisting of β-carotene-linoleic acid, superoxide radical scavenging activity (enzymatically/nonenzymatically) and XO inhibitory activity. A dose response curve was plotted for determining SC 50 and IC 50 values for expressing the results of free radical scavenging activity and XO inhibitory activities respectively. Results: The high polyphenolic content of CCM and CCMW extract showed highest antioxidant activity irrespective the method used for this investigation. The overall results decreased in the order of: CCM > CCMW > CCC > CCH. CCH extract was inactive towards chemically generated superoxide radical and poor DPPH radical scavengers. The results of LPO inhibitory activities of leaves extract (0.1, 0.5 and 1.0 mg/mL) also decreased in the order of: CCM > CCMW > CCC > CCH. Overall 1.0 mg/mL leaves extract showed highest antioxidant potency amongst the studied concentration. Conclusion: CCMW and CCM extract of C. colocynthis exhibited promising antioxidants and XO inhibitory activities.

Kazuya Murata, Yumi Abe, Kaito Shinohara, Megumi Futamura-Masuda, Akemi Uwaya, Fumiyuki Isami, Hideaki Matsuda
July-September 2014, 6(3):260-265
DOI:10.4103/0974-8490.132608  PMID:25002809
Background: Morinda citrifolia (Rubiaceae), commonly known as noni is distributed throughout tropical and sub-tropical regions of the world. Anti-allergic effects of noni have not been reported despite the clinical usage as an anti-allergic agent. Materials and Methods: To investigate the anti-allergic effects of the 50% ethanolic extract of M. citrifolia fruits and leaves (MCF-ext and MCL-ext), dinitrofluorobenzene (DNFB)-induced triphasic cutaneous reaction and picryl chloride-induced contact dermatitis (PC-CD) tests were performed. Results: In DNFB-induced triphasic cutaneous reaction, oral administration of MCF-ext and MCL-ext exhibited dose-dependent inhibition of cutaneous reaction at 1 h (immediate phase response) after the DNFB challenge. MCF-ext also inhibited ear swelling at 24 h (late phase response) and 8 days (very late phase response) after the DNFB challenge. The effect of MCL-ext on the immediate phase response was attributed to the anti-degranulation from RBL-2H3 cells, while MCF-ext had no significant effect on degranulation. The active components of anti-degranulation activity in MCL-ext were determined to be ursolic acid, rutin and kaempferol-3-O-α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranoside. In the PC-CD test, both MCF-ext and MCL-ext showed an anti-swelling effect but the potency of MCF-ext was stronger than MCL-ext. Conclusion: These data suggest that noni fruits and leaves can be a daily consumable material for the prevention of allergic symptoms.

July-September 2014, 6(3):251-256
DOI:10.4103/0974-8490.132606  PMID:25002807
Background: According to Thai traditional medicine, Pentace burmanica Kurz. stem bark has been used as crude drug for treating diarrhea. However, the crude drug is also found susceptible to adulteration. Objectives: To develop specific standardization parameters of P. burmanica stem bark in Thailand and to determine the (+)-catechin and (-)-epicatechin contents of P. burmanica stem bark by HPLC analysis. Materials and Methods: P. burmanica stem barks from various sources throughout Thailand were investigated according to WHO guideline of the pharmacognostic specification. High performance liquid chromatography (HPLC) was performed for (+)-catechin and (-)-epicatechin quantification. Results: Macroscopic evaluation was demonstrated as whole plant drawing. Microscopic evaluation of stem bark powdered drug showed fragment of fibers, resin masses, tannin masses, starch grain, calcium oxalate, and fragment of parenchyma. Physico-chemical parameters revealed that total ash, acid insoluble ash, loss on drying, and water content should be not more than 3.58, 0.50, 8.40, and 9.70% of dry weight respectively; while ethanol and water soluble extractive values should not be less than 21.90 and 19.06% of dry weight respectively. Both (+)-catechin and (-)-epicatechin were existed in P. burmanica ethanolic extract. Owing to the small amount of (+)-catechin, quantitation of its content was omitted. However, (-)-epicatechin contents was found as 59.74 ± 1.69μg/mg of crude extract. Conclusion: The pharmacognostic investigations can be used to set the standard parameters of P. burmanica stem bark in Thailand. HPLC method can be applied to determine (+)-catechin and (-)-epicatechin content in plant materials.

July-September 2014, 6(3):210-217
DOI:10.4103/0974-8490.132598  PMID:25002801
Background: Gentamicin, a strong cationic drug accumulated at biological membranes causes net increase in oxidative stress and lipid peroxidation leading to necrotic changes in renal tubles and consequently precipitates acute nephrotoxicity. Several phytoconstituents and plants extracts demonstrated significant anti-oxidant and cyto-protective activities. Vitex negundo Linn. (VN), Oroxylum indicum Vent. (OI) and Barringtonia acutangula Linn. (BA) are widely found throughout the Asian sub-continent including India, used extensively in different forms of Indian traditional medicine like Ayurveda and Unani. Objective: Nephroprotective activity of extracts of VN roots, OI whole plant and BA leaves were investigated against experimentally induced acute nephrotoxicity [Gentamicin (i.p; 80mg/kg for 7 days)] in Wistar rats as test animals. Materials and Methods: The rats were treated with Cystone (5 mL/kg; p.o) taken as positive control and methanol-dichloromethane (1:1) extracts of VN, OI and BA (200 mg/kg; p.o) as test drugs for 7 days. Following the said treatments, biochemical parameters of urine (volume, creatinine and lactate dehydrogenase (LDH)) and serum (urea, creatinine, albumin and total protein) were estimated. Renal anti-oxidant markers viz., superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and lipid peroxidation (LPO) in renal tissue were assayed. Tissue sections of kidneys from different groups were made and histopathological features were observed. Result: The extracts of VN, OI and BA significantly attenuated the nephrotoxicity by elevation of body weight, CAT, GPx and SOD or lowering urine LDH and creatinine, serum urea; serum creatinine and LPO respectively. Histopathological score of VN, OI and BA treated groups were 1+, 2+ and 2+ respectively against 4+ of the toxic group. Conclusion: The findings suggested the significant nephroprotection of VN roots followed by OI whole plant and BA leaves.
