Abstract

Two new selaginellin derivatives selaginellin P (1) and selaginellin Q (2) were isolated from Selaginella tamariscina. The structures of 1 and 2 were established as 2,4'-dihydroxy-4-methyl-3-[(4-hydroxyphenyl)ethynyl]biphene (1) and 2,4'-dihydroxy-3-[(4-hydroxyphenyl)ethynyl]biphene (2) on the basis of spectroscopic means including HR-ESI-MS, 1D, and 2D NMR experiments.

摘要

从卷柏中分离得到两个新的卷柏素衍生物卷柏素P（1）和卷柏素Q（2）。通过高分辨电喷雾电离质谱（HR-ESI-MS）、一维和二维核磁共振实验等光谱手段确定了1和2的结构分别为2,4'-二羟基-4-甲基-3-[(4-羟基苯基)乙炔基]联苯（1）和2,4'-二羟基-3-[(4-羟基苯基)乙炔基]联苯（2）。
