Methods: Aqueous, petroleum ether, chloroform, ethanol and acetone extracts were prepared by adding 100 g of leaf powder to 1000 ml of these solvents and subjected to soxhlet extraction. The extracts were concentrated by using vacuum evaporator and dried at 60 ^oC. Preliminary phytochemical screening was performed by Harborne method. Total tannin and flavonoid content was determined by using Folin Ciocalteau reagent and Aluminium Chloride method respectively.

Results: Different extracts showed the bioactive components such as alkaloids, carbohydrates, glycosides, coumarins, quinones, saponins, steroids, terpenoids, proteins, phytosterols, tannins and flavonoids. Total tannins content in the ethanolic leaf extract was estimated as 0.042µg/µl and flavonoids content was estimated as 0.045µg/µl.

Conclusion: The findings of the study revealed that various chemical constituents present in the leaf extracts of G. asiatica is rich in phytopharmaceutical importance.
