Abstract

Two new phenethyl alcohol glycosides, darendoside A and B (= deacyl martynoside) were isolated from the methanolic extract of the aerial parts of Scutellaria orientalis subsp. pinnatifida, along with four known glycosides, syringin, martynoside, leucosceptoside A and verbascoside. On the basis of chemical and spectral evidence the structures of darendoside A and B were determined as beta-(4-hydroxyphenyl)ethyl O-beta-D-apiofuranosyl-(1-->2)-O-beta-D-glucopyranoside and beta-(3-hydroxy-4-methoxyphenyl)ethyl O-alpha-L-rhamnopyranosyl-(1-->3)-O-beta-D-glucopyranoside (= deacyl martynoside), respectively.

摘要

从东方黄芩狭叶变种地上部分的甲醇提取物中分离出两种新的苯乙醇苷，即达伦多苷A和B（=去酰基马钱苷），以及四种已知的苷，即紫丁香苷、马钱苷、白苞筋骨草苷A和毛蕊花糖苷。基于化学和光谱证据，达伦多苷A和B的结构分别被确定为β-(4-羟基苯基)乙基O-β-D-芹菜呋喃糖基-(1→2)-O-β-D-吡喃葡萄糖苷和β-(3-羟基-4-甲氧基苯基)乙基O-α-L-鼠李吡喃糖基-(1→3)-O-β-D-吡喃葡萄糖苷（=去酰基马钱苷）。
