CASPILLAN, RONALD MARI JERARD R., ERANA, CHRISTIAN EARLP., REYES, GIERONE LIANNI A. Isolation and Antidiabetic Activity of the chemical components from Bignai Leaves (Antidesma bunius).

This study entitled “Isolation and Antidiabetic activity of the chemical components from Bignai Leaves (Anfidesma bunius)” was conducted to: determine the physical properties of isolates from bignai in terms of color, odor, texture, and solubility; determine the phytochemical components from bignai and; test the antidiabetic activities of each component present in bignai.
The isolates were obtained using column chromatography and their physical properties were evaluated in terms of odor, color, texture and solubility. Phytochemical analysis was also determined by identifying the presence of glycosides, saponins, flavonoids and terpenoids from the bignai isolates. Furthermore, the antidiabetic activity was tested using the oral glucose tolerance test on the laboratory rats.
The findings revealed brown color from the 30%, 60%, 90% and 100% acetone. The results also revealed that all isolates have a pungent odor and greasy texture. The results showed that the isolate from 100% DCM was found insoluble in both distilled water and petroleum ether but soluble in both methanol and ethanol. Meanwhile, the 30%, 60%, 90% and 100% acetone were found insoluble in distilled water but soluble in petroleum ether, methanol, and ethanol.
The results revealed that the isolates from DCM, 30%, 60% and 100% acetone have glycosides. On the other hand, the presence of saponins was found only from 60%, 90% and 100% acetone. The presence of flavonoid was found in 30%, 60% and 100% acetone. In addition, terpenoids was identified in DCM, 30%, 60% and 100% acetone. The mean zone of glucose reduction of the glucose reduction of the DCM was 22.60, the 30% acetone was 20.40. the 60% acetone was 17.40, the 90% acetone was 8.80, and the 100% acetone was 10.60.
Based on the results, the isolates showed glucose reduction but exhibited low antidiabetic activity.
