Inhibitory activity of Gypensapogenin D against α-glucosidase and preparation of its liposomes

Abstract

Gynostemma pentaphyllum is a functional food that is commercially available worldwide. Triterpenoid saponins are the main active components in Gynostemma pentaphyllum, which are usually hydrolyzed into triterpene sapogenins in organisms to play a pharmacological role. Gypensapogenin D is a triterpene sapogenins with the highest content in the hydrolysate of gypenoside. In addition, it was found that Gypensapogenin D had a certain inhibitory effect on α-glucosidase. In view of the poor solubility of Gypensapogenin D, which affects its bioavailability, Gypensapogenin D was prepared as a liposomal formulation in this paper, which provides valuable data for the later in-depth study and drug development and utilization of this compound.
