石菖蒲中多糖成分的分析

Isolation and identification of the polysaccharide of Acorus gramincus Soland

本文对中药石菖蒲 Ａｃｏｒｕｓ ｇｒａｍｉｎｅｕｓ Ｓｏｌａｎｄ中所含多糖进行初步研究，分离纯化得一白色精制多糖，经分析表明组成它的单糖为葡萄糖。并采用苯酚－硫酸法测得其生药中含量为１２．２２％，用凝固点下降法测得分子量为３１５１．６。研究结果提示，在中药制剂及制定有关石菖蒲的质量标准时，对其中多糖成分应予重视。

The polysaccharide of Acorus gramineus has been isolated by water extraction from its rhizome. The polysaccharide of A.gramineus was composed of D - glucoses. It's average molecular weight was 3151. 6 which was determined by solidifying point drop method and the polysaccharide content of A. gramineus was 12 .22% determined by Phenol - H_2SO+4 method.
