| Abstract|| |
Background: Cordia dichotoma G. Forst. is an important medicinal plant of family Boraginaceae. Traditionally, its leaves are used to treat fever, headache, and joint pain but its medicinal activities have not been proven by research. Objective: To evaluate the analgesic, anti-inflammatory, and antipyretic activity of C. dichotoma G. Forst. leaf extract.
Material and Methods: The various extracts of leaf powder were prepared by using soxhlet apparatus. The methanol extract was selected for pharmacological study. To evaluate analgesic activity, Eddy's hot plate method, to study anti-inflammatory activity, carageenan-induced rat paw edema method, and to study antipyretic activity, yeast-induced pyrexia method was used. SD female rats (180-200 g) were used for the study. Results: In all three tests, the methanol extract high dose (400 mg/kg) was found to be highly significant as compared to standard drug. Conclusion: This study proved the traditional uses of plant leaves and concluded the analgesic, anti-inflammatory, and antipyretic activity of the leaf methanol extract.
Keywords: Analgesic, anti-inflammatory, antipyretic, Boraginaceae, Cordia dichotoma

| Introduction|| |
The genus Cordia belongs to the family Boraginaceae, with some 300 species distributed worldwide, mostly in the warmer regions of the World. According to a literature survey, several uses in traditional medicine have been reported for different Cordia species. The ethnopharmacological and chemotaxonomic importance of the genus Cordia led us to investigate one of its species, namely Cordia dichotoma G. Forst., which is a medicinal plant found widespread from northern India to southern China. Chemical screening of both the leaves and the fruits showed the presence of pyrrolizidine alkaloids, coumarins, flavonoids, terpenes, and sterols. Four flavonoid glycosides (robinin, rutin; rutoside, datiscoside, and hesperidin), a flavonoid aglycone (dihydrorobinetin), and 2 phenolic derivatives (chlorogenic acid and caffeic acid) were isolated from fruits and leaves.  The fruit used as astringent, anthelmentic, diuretic, demulcent, and expectorant. The mucilage of the fruit treats coughs and other chest complaints. It is also used to treat uterus and urethra disorders. The powder form of the fruit kernels is mixed with oil to heal tinea. The plant is also a diuretic and laxative.  The leaves used as tonic, stimulant, and febrifuge. Leaf decoction used in cough and cold.  The leaves are also used to relieve headache and treat ulcers. The present work aimed to investigate the analgesic, anti-inflammatory, and antipyretic activity of C. dichotoma G. Forst leaf.
| Materials and Methods|| |
The leaves of C. dichotoma G. Forst., family Boraginaceae were procured from Attari, Anandpur Sahib and authenticated and identified by Dr. H.B Singh, Scientist and Head, Raw material, Herbarium and museum, NISCAIR, New Delhi. The voucher specimen of the sample (NISCAIR/RHMD/Consult/-2011-12/1788/88) was deposited in herbarium of Pharmacognosy department, ASBASJSM College of pharmacy, Bela (Ropar) for future with reference no. JCD/11/03.
Chemicals and reagents
All chemicals, reagents and solvents used were of AR and HPLC grade (Loba, Himedia, Qualigen). Distilled water and precoated silica gel G plates (6 × 6 inches, 0.2 mm thickness, aluminium base, E Merck) were used.
A definite weight of crude leafy drug was taken in a soxhlet apparatus thimble after making moderately coarse and then continuous hot soxhlet extraction was done by various solvents in a sequence of increasing polarity as follows:  Petroleum ether, chloroform, methanol, and water. Before starting extraction with subsequent solvent, the marc (plant material) was dried of all its previous solvent content by spreading out on paper. The weight of the extract obtained was determined after concentration in Heidolph Rota evaporator, and the percentage of extractive value was calculated on dry weight basis.
The various chemical tests were performed on each extract to determine presence of different phytoconstituents such as alkaloids, glycosides, flavonoids, steroids, carbohydrates, saponins, etc. , The total alkaloid,  total flavonoid,  and total phenolic content  were also determined in the crude drug sample.
The methanol extract of C. dichotoma leaves was used to evaluate its analgesic, anti-inflammatory, and antipyretic activity. SD female rats (180-200 g) were used for the present study. They were maintained under standard environmental conditions and were feed with standard pellet diet. The experimental protocol was approved by the Institution Animals Ethics Committee (IAEC) of ASBASJSM College of Pharmacy, Bela (Ropar) Punjab under the accession no. ASCB/IAEC/04/12/61. Animals were procured from NIPER, Mohali. Animals were housed in polypropylene cages (6 per cage) with dust free rice husk as a bedding material under laboratory condition with control environment of temperature (23° ± 2°C), humidity (60% ± 10%), and 12 h light/dark cycles as per guidelines of the Committee for the Purpose of Control and Supervision of Experiments on Animals (CPCSEA), India. They were provided standard rodent chow/feed and water ad libitum. Before subjecting them to experimentation, the animals were given a week time to get acclimatized with laboratory conditions. The animals were fasted for 18 h before the experiment. After a sufficient period of acclimatization, they were used to evaluate anti-inflammatory, anti-pyretic, and analgesic activities of C. dichotoma.
Grouping of animals
Twenty-four animals were used in all; six animals were used in each group.
- Group I: Positive control group
- Group II: Standard group
- Group III: C. dichotoma low dose level of leaf extract
- Group IV: C. dichotoma high dose level of leaf extract.
Analgesic activity was analyzed by Eddy's Hot plate method. ,,, Indomethacin (10 mg/kg per oral) was taken as standard drug. Rats were placed on hot plate and recorded the reaction time in second for licking of hind paw or jumping with cut- off time of 20 sec. The reaction time following the administration of the test extracts, reference standard drug, and control saline vehicle were measured at 0, 30, 60, 90, and 120 min.
Anti-inflammatory activity was analyzed by the carrageenan-induced rat paw edema method. ,, Indomethacin (10 mg/kg per oral) was taken as standard drug.
Antipyretic activity was analyzed by the method Yeast- induced Pyrexia. , Paracetamol (100 mg/kg per oral) was taken as standard drug. The test substance was dosed orally (0 hour), and rectal temperature was recorded at 1, 2, 3, and 4 hours. The difference in temperature between 0 hour and at the end of 4 hour was compared and analyzed.
The data was expressed in mean SEM, and the test dose was compared with control and subjected to one-way ANOVA followed by Dunnett Test. P < 0.05 was considered significant, P < 0.01 more significant, and P < 0.001 highly significant.

| Discussion|| |
In this study, CDME showed positive results and its high dose (400 mg/kg) was found be highly significantly effective as analgesic, anti-inflammatory, and anti-pyretic drug compared to effects of low dose. Its anti-inflammatory potential was found lesser as compared to the other two effects. The effect of high dose was increasing with time, but the maximum time limit for its effects could not be elucidated because of the limited time of the study. This is the first study showing the antipyretic potential of C. dichotoma plant leaves.
| Conclusion|| |
In conclusion, the present study supports the traditional use of C. dichotoma G. Forst. leaves methanol extract as analgesic, antipyretic, and anti-inflammatory drug. However, the crude extracts of this plant need to be further purified through isolation and identification of the responsible compound for these above activities. The mechanism of action of C. dichotoma G. Forst. leaves may be another interested area to work in future.
