Abstract

A new neolignan glycoside named armaoside (1), together with six known compounds (2-7), have been isolated from the whole plant of Pedicularis armata Maxim. The structure of 1 was elucidated as erythro-(7S,8R)-1-(4-O-beta-D-glucopyranosyl-3-methoxyphenyl)-2-[3,5-dimethoxyl-4-oxo-cinnamic aldehyde]propane-1, 3-diol by spectroscopic and chemical methods. All compounds were assayed against Bacillus subtilis, Escherichia coli, and Staphylococcus aureus.

摘要

从长花马先蒿（Pedicularis armata Maxim）全草中分离得到了一种名为马先蒿苷（1）的新木脂素糖苷以及六种已知化合物（2 - 7）。通过光谱和化学方法确定1的结构为赤式-（7S，8R）-1-（4 - O-β-D-吡喃葡萄糖基-3-甲氧基苯基）-2-[3,5-二甲氧基-4-氧代肉桂醛]丙烷-1,3-二醇。对所有化合物进行了针对枯草芽孢杆菌、大肠杆菌和金黄色葡萄球菌的活性测试。
