The hexane and chloroform extracts

The hexane and chloroform extracts of Derris scandens have displayed potent -glucosidase inhibitory and moderate free radical scavenging
activities. Phytochemical investigation of the active extracts led to the isolation of three new prenylated isoflavones, isoscandinone, scandenin A
and scandenin B in addition to scandenone, scandinone and 4, 5, 7-trihydroxybiprenylisoflavone as the main constituents, having -glucosidase
enzyme inhibitory and free radical scavenging properties. A reversed-phase HPLC method is developed to quantify these active principles in the
plant material, which can serve as an effective quality control method for standardization of D. scandens.
