不同产地太子参中化学成分分析

目的:研究不同产地太子参中化学成分。方法:采用原子吸光光谱法测定微量元素Cu、Fe、Zn、Mn、C a、M g、S e、C o的含量;紫外分光光度法测定多糖、皂苷的含量;G C-M S分析鉴定挥发性提取物。结果:贵州施秉产太子参中Fe、Mn、Mg、Ca、Co和皂苷含量最高;福建柘荣产太子参中Zn和Se含量最高、浙江磐安产太子参中Cu和多糖含量最高、挥发性化合物组分之间没有较大差异,但各组分含量因产地不同而有一旦差异,浙江磐安产太子参鉴定出29种,贵州施秉产太子参鉴定出28种,福建柘荣产太子参鉴定出25种挥发性化合物。结论:太子参化学成分及含量受种植环境和品种类型的影响,贵州具有适宜太子参生长的土壤和气候。

Chemical Compositions of Pseudostellaria heterophylla (Miq.) Pax Cultivated in Different Regions

Objective: To analyze chemical constituents of Pseudostellaria heterophylla(Miq.) Pax cultivated in different regions.Methods: The contents of trace elements(Cu,Fe,Zn,Mn,Ca,Mg,Se and Co) were determined by atomic absorption spectrophotometry,saponins and polysaccharide were determined by ultraviolet spectrophotometry,and volatile components were identified by GC-MS.Results: The highest contents of trace elements such as Fe,Mn,Mg,Ca and Co as well as saponins were determined in Pseudostellaria heterophylla(Miq.) Pax cultivated in GuiZhou.The highest contents of trace elements of Zn and Se were observed in Pseudostellaria heterophylla(Miq.) Pax cultivated in Fujian.The contents of Cu and polysaccharide were detected in Pseudostellaria heterophylla(Miq.) Pax cultivated in Zhejiang.Pseudostellaria heterophylla(Miq.) cultivated in different regions had different volatile components.Totally 29,28 and 25 volatile components were identified in Pseudostellaria heterophylla(Miq.) Pax cultivated in Zhejiang,Guizhou and Fujian.Conclusion: Environment and breed type could effect on the contents of chemical compositions.The soil and climate of Guizhou are suitable for the healthy growth of Pseudostellaria heterophylla(Miq.).
