石菖蒲中多糖成分的分析
Isolation and identification of the polysaccharide of Acorus gramincus Soland
-
摘要: 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.Abstract: 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-H2SO4 method.
