STUDY ON ANTI-α-GLUCOSIDASE OF CURCUMIN ISOLATED FROM CURCUMA LONGA RHIZOMES
Main Article Content
Abstract
The rhizome or yellow Turmeric root in Traditional Medicine is called Khuong Hoang. This medicinal herb is widely used in many Asian countries, including Vietnam, as a spice and medicine. The main active ingredients in Turmeric are diarylheptanoids, including curcumin. This study investigated the in vitro α-glucosidase inhibitory effect of curcumin. The results showed that curcumin has the ability to strongly inhibit α-glucosidase with IC50 7.73±0.62 µg/ml.
