Phytochemical Nature and Pharmacological Evaluation of Chloroform Extract of Pandanus Fascicularis L. (fruits) an in Vivo Study

The current study was undertaken to investigate analgesic, anti-pyretic, anti-inflammatory, and gastrointestinal (GI) motility of fruit extract of P. fascicularis L. The analgesic potentials of plant extract was screened by using the acetic acid-induced writhing test. Antipyretic study was done by yeast induced pyrexia. The extracts were used for anti-inflammatory studies by albumin induced edema over a period of time; finally, gastrointestinal (GI) motility test was performed using charcoal. The chloroform extracts showed presence of maximum phytochemicals such as alkaloid, tannin, saponin, steroid, terpenoid, protein, flavonoid etc. In case of analgesic assay the dose of 400 mg/kg was capable of inhibiting 62.96% writhing in comparison to standard Diclofenac sodium, while our antipyretic assay were resembled initial (38.7 ± 0.45°C) and final (37.83 ± 0.37°C) rectal temperatures when treated with chloroform extract (400 mg/kg); where the values for Acetyl salicylic acid (100 mg/kg) were found 38.4 ± 0.11oC and 37.5 ± 0.010°C respectively. During anti-inflammatory assay edema was reduced from 0.62 ± 0.06 to 0.45 ± 0.02 after 5 h of administration of chloroform extract (400 mg/kg), where aspirin did this from 0.60 ± 0.002 to 0.42 ± 0.01 at 200 mg/ kg dose. The motility rates of castor oil and chloroform extract were found 53.24%and 31.78% at 10 ml/kg and 400 mg/kg respectively, where the control represented 63.68% motility rate. These results show that, chloroform extract of fruit of P. fascicularis L. has significant analgesic, anti-pyretic, anti-inflammatory and gastrointestinal (GI) motility effects that increase with the increase of concentration. It can be assumed that, phytochemicals present, are the source of potency of the chloroform extract.
