【摘要】 目的 研究楮头红的化学成分。方法 用经典的中草药化学成分提取分离方法,借助系统预试验初步判断楮头红所含的化学成分,用苯酚-硫酸法测定其多糖总量,用原子吸收法测定部分营养元素含量。结果 楮头红含还原多糖平均为75g/kg,含Mg、Zn、Mn、Cu分别为205.446±6.00、50.279±2.25、319.294±12.00 、10.867±0.36mg/kg,含Ca、Fe、K分别为 13.501±0.24、1.268±0.56 和17.467±0.36g/kg,此外还含有游离苷类物质、黄酮类物质、酚类、鞣质等物质。结论 楮头红所含的生物活性成分与临床药效基本一致。 【关键词】 楮头红;化学成分;多糖;营养元素 【Abstract】 Objective To study the chemical components of S.nepalensis Wall.Methods The chemical components of S.nepalensis Wall were extracted by classical extraction and the primary composition of the extract were estimated with qualitative analysis. The content of polysaccharide and some nutrient elements were determined with phenol-sulfuric acid and atomic absorption spectrophotometry (AAS) respectively.Results The average content of polysaccharide in S.nepalensis Wall was 75 g/kg,the content of nutrient elements Mg、Zn、Mn、Cu were 205.446±6.00、50.279±2.25、319.294±12.00 、10.867±0.36(mg/kg)respectively,and Ca、Fe、K were 13.501±0.24、1.268±0.56 和17.467±0.36(g/kg)respectively. Again there were other compo……
