Abstract

Two new saponins, 3-O-[6-O-sulfonyl-beta-d-glucopyranosyl-(1-->3)]-alpha-l-arabinopyranosyl pseudojujubogenin (1) and 3-O-[alpha-l-arabinofuranosyl-(1-->2)]-alpha-l-arabinopyranosyl jujubogenin (2), a new matsutaka alcohol derivative, (3R)-1-octan-3-yl-(6-O-sulfonyl)-beta-d-glucopyranoside (3), a new phenylethanoid glycoside, 3,4-dihydroxyphenylethyl alcohol (2-O-feruloyl)-beta-d-glucopyranoside (4), and a new glycoside, phenylethyl alcohol [5-O-p-hydroxybenzoyl-beta-d-apiofuranosyl-(1-->2)]-beta-d-glucopyranoside (5), were isolated from Bacopa monniera. Their structures were established by NMR, MS, and chemical methods.

摘要

从假马齿苋中分离出两种新皂苷，3-O-[6-O-磺酰基-β-D-吡喃葡萄糖基-(1→3)]-α-L-阿拉伯吡喃糖基假桔梗皂苷元（1）和3-O-[α-L-阿拉伯呋喃糖基-(1→2)]-α-L-阿拉伯吡喃糖基桔梗皂苷元（2），一种新的松田醇衍生物，(3R)-1-辛烷-3-基-(6-O-磺酰基)-β-D-吡喃葡萄糖苷（3），一种新的苯乙醇苷，3,4-二羟基苯乙醇(2-O-阿魏酰基)-β-D-吡喃葡萄糖苷（4），以及一种新的糖苷，苯乙醇[5-O-对羟基苯甲酰基-β-D-阿吡喃呋喃糖基-(1→2)]-β-D-吡喃葡萄糖苷（5）。它们的结构通过核磁共振、质谱和化学方法确定。
