Three new compounds (6,9)-6'-galloyl-roseoside (), purpurogallin ethyl carboxylate (), and tibetana A () were isolated from 80% methanol extract of the leaves of Hance. Their structures were elucidated based on comprehensive spectroscopic methods and chemical data, including optical rotation, UV, MS, 1 D and 2 D NMR spectra. Compounds and were evaluated for their -glucosidase inhibitory activity, pancreatic lipase inhibitory activity, and tyrosinase inhibitory activity.
