稿本《荀子微言》成书流传考

《荀子微言》是惠栋仅存的一部荀学著作。此书当是惠氏晚年在校阅《荀子》时摘抄其中精要之言并稍加注解而成。书中讹误颇多,可见其成书后并未加校正。此书未曾刊刻,其稿本先后保存于沈大成、梅春、松江韩氏读有用书斋等处,今藏上海图书馆。

Chemical Constituents of Pomatosace filicula

A new triterpenoid saponin, namely pomatoside A (3) 13beta, 28-epoxy-16-oleananone-3-O-[alpha-L-rhamnopyranosyl-(1 -->6)-O-beta-D-glucopyranosyl-(1 -->4)-O-beta-D-glucopyranosyl-(1 -->6)-O-beta-D-glucopyranosyl-(1 -->2)]-beta-D-glucopyranoside, together with twelve known compounds, was isolated for the first time from Pomatosace filicula Maxim., a monotypic endemic plant, grown in the Qinghai-Xizang Plateau of China. Their structures were elucidated by spectroscopic analyses and chemical methods, especially 2D-NMR.
