Abstract

A novel O-heteroside, (3RS,4RS)-3,4-dihydroxy-4-(2-hydroxy-5-acetylphenyl)-2-[(beta-O-glucopyranosyl)methyl]-but-1-ene (1), named nauplathizine, and a previously known compound, acetophenone-4-O-glucoside (2), were isolated from the antibacterial acetone extract of the aerial parts of Nauplius aquaticus (L) (Asteraceae, Inulae). The structure of 1 was established via its acetylated derivative by means of spectroscopic and chemical data.

摘要

从水生海盘车（菊科旋覆花属）地上部分的抗菌丙酮提取物中分离出一种新型O-糖苷，即(3RS,4RS)-3,4-二羟基-4-(2-羟基-5-乙酰基苯基)-2-[(β-O-吡喃葡萄糖基)甲基]-丁-1-烯（1），命名为海盘车嗪，以及一种已知化合物苯乙酮-4-O-葡萄糖苷（2）。通过光谱和化学数据，借助其乙酰化衍生物确定了1的结构。
