Three new phenethyl alcohol glycosides together with six known compounds have been isolated from the leaves of Stachys sieboldii. On the basis of chemical and spectral analyses, the structures of three new compounds named stachysosides A, B and C have been established as 2-(3,4-dihydroxyphenyl)ethyl O-alpha-L-arabinopyranosyl-(1----2)-alpha-L-rhamnopyranosyl- (1----3)-4-O-E-caffeoyl-beta-D-glucopyranoside, 2-(3,4-dihydroxyphenyl)ethyl O-alpha-L-arabinopyranosyl-(1----2)-alpha-L-rhamnopyranosyl- (1----3)-4-O-E-feruloyl-beta-D-glucopyranoside and 2-(3-hydroxy-4-methoxyphenyl)ethyl O-alpha-L-arabinopyranosyl-(1----2)-alpha-L-rhamnopyranosyl- (1----3)-4-O-E- feruloyl-beta-D-glucopyranoside, respectively.
从水苏叶中分离出了三种新的苯乙醇苷以及六种已知化合物。基于化学和光谱分析，三种新化合物水苏苷A、B和C的结构分别被确定为2-(3,4-二羟基苯基)乙基O-α-L-阿拉伯吡喃糖基-(1→2)-α-L-鼠李吡喃糖基-(1→3)-4-O-E-咖啡酰基-β-D-吡喃葡萄糖苷、2-(3,4-二羟基苯基)乙基O-α-L-阿拉伯吡喃糖基-(1→2)-α-L-鼠李吡喃糖基-(1→3)-4-O-E-阿魏酰基-β-D-吡喃葡萄糖苷和2-(3-羟基-4-甲氧基苯基)乙基O-α-L-阿拉伯吡喃糖基-(1→2)-α-L-鼠李吡喃糖基-(1→3)-4-O-E-阿魏酰基-β-D-吡喃葡萄糖苷。
