Abstract

Two new physalins, 7α-hydroxy-5-deoxy-4-dehydrophysalin IX () and 5-deoxy-4-dehydrophysalin IX (), together with six known compounds, luteolin (), luteolin-7--glucoside (), neoechinulin A (), 3-(4-hydroxy-3-methoxyphenyl)--(4-methylphenyl)-2-propenamide (), physalin D () and blumenol A () were isolated from L. var. (Mast.) Makino. Their structures were elucidated by NMR spectroscopic analysis, HR-ESI-MS, X-ray crystallographic data analysis and comparison with the known compounds. Among them, compounds and were isolated from the genus for the first time. Compound exhibited weak NAD(P)H: quinone reductase (QR) inducing activity.

摘要

从 L. var. (Mast.) Makino 中分离得到两个新的 physalins,7α-羟基-5-去氧-4-去氢 physalin IX () 和 5-去氧-4-去氢 physalin IX (),以及六个已知化合物,木犀草素 ()、木犀草素-7-O--葡萄糖苷 ()、新绵马素 A ()、3-(4-羟基-3-甲氧基苯基)-()-(4-甲基苯基)-2-丙烯酰胺 ()、physalin D () 和 blumenol A ()。通过 NMR 光谱分析、高分辨率电喷雾电离质谱 (HR-ESI-MS)、X 射线晶体学数据分析以及与已知化合物的比较,确定了它们的结构。其中,化合物 和 是首次从属中分离得到的。化合物 表现出较弱的 NAD(P)H:醌还原酶 (QR) 诱导活性。
