【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 atomicabsorption 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 composition in the extract, including glycosides, flavones, phenols and tannins etc.Conclusion It is consistent basically that the chemical components in S.nepalensis Wall with its clinical effects. ......
