摘要
Objective: To evaluate analgesic, hypoglycemic, anxiolytic, and anthelmintic activities with phytochemical screening of methanolic extract of Tabernaemontana recurva (T. recurva) whole plants. Methods: The plant parts of T. recurva were collected, dried, powdered and extracted with methanol. Then the extracts were subjected to in vivo analgesic, hypoglycemic, anxiolytic activity in mice model and in vitro anthelmintic activity. Results: The analysis of phytochemical screening confirmed the existence of alkaloid, saponin, tannins, carbohydrate, phytosterols, glycosides and phenol. In analgesic test, a significant level of percentage inhibition of abdominal constriction was observed with concentration of 200 and 400 mg/kg of body weight of extract and this was found better with formalin induced hind paw licking test rather than acetic acid induced writhing test. In hypoglycemic test, it was observed that concentration 200 mg/kg reduced blood sugar level slightly while concentration 400 mg/kg increased glucose level by 22.95%. A significant level of anxiolytic activity was observed for the study plant extract. The extract revealed potent anthelmintic activity at different concentrations. Conclusions: In light, the methanolic extract of T. recurva exhibited excellent anthelmintic, anxiolytic and analgesic activity. This plant showed moderate hypoglycemic effect at lower concentration but higher concentration increased blood glucose level.
