[摘要]
首次从翻白叶Potentill agriffithiiHook.f.var.velutinaCard.全草的甲醇提取物中分得6个化合物,分别为黄酮苷和三萜类化合物。经光谱及化学方法分别鉴定为翻白叶苷A(potengriffiosideA,)、委陵菜酸(tormenticacid,)、野蔷薇苷(rosamultin,)、euscaphicacid()、kaji-ichigosideF1()、24-deoxy-sericoside()。其中化合物为新化合物,其结构为山柰酚-3-O-β-D-6-O-(对羟基桂皮酰基)-吡喃葡萄糖苷〔kaempferol-3-O-β-D-6-O-(p-hydroxycinnamoyl)-glucopyranoside〕。

[Abstract]
A new flavone glycoside named potengriffioside A (Ⅰ) together with five known triterpenoids——tormentic acid (Ⅱ), rosamultin (Ⅲ), euscaphic acid (Ⅳ), kaji-ichigoside F 1 (Ⅴ) and 24-deoxy-sericoside (Ⅵ) were isolated from the methanol extract of the whole plant of Potentilla griffithii Hook f var velutina Card (Rosaceae) for the first time Based on spectroscopic and chemical evidences, the structure of potengriffioside A (Ⅰ) was elucidated as kaempferol-3-O-β-D-6-O-(p-hydroxycinnamoyl) glucopyranoside
