This work describes the isolation and characterization of 3 compounds, including physalin B (1), physalin G (2) and quercetin 3-O-rutinoside (3) from the dichloromethane and n-butanol extracts of the aerial parts of the medicinal species Physalis angulata L. collected from Dong Thap province. The chemical structures were elucidated based on various spectra data (ESI-MS, 1D- and 2D-NMR spectroscopy) and by comparing with known spectral data. For the first time, the inhibition activity of physalin G on α-glucosidase enzyme was announced.
