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.
从 的叶 80%甲醇提取物中分离得到了 3 个新化合物（6,9）-6′-没食子酰基蔷薇苷（）、紫铆因乙酯（）和藏红花 A（）。基于全面的光谱方法和化学数据，包括旋光、UV、MS、1D 和 2D NMR 光谱，确定了它们的结构。对化合物 和 进行了 -葡萄糖苷酶抑制活性、胰脂肪酶抑制活性和酪氨酸酶抑制活性评价。
