α-Glucosidase and α-amylase Inhibitory Constituents of Tinospora crispa: Isolation and Chemical Profile Confirmation by Ultra-high Performance Liquid Chromatography-quadrupole Time-of-flight/mass spectrometry

Tinospora crispa has been used in Malaysia to treat diabetes mellitus. We evaluated the effects of compounds isolated from T. crispa vines on the starch digestive enzymes, α-glucosidase and α-amylase. Borapetoside C was the most potent α-glucosidase inhibitor (IC50 = 0.0527 ± 0.008 mg/ml), followed...
