不同产地蒺藜品质比较研究

Quality Study of Tribulus Terrestris from Different Areas

目的：建立蒺藜果中总皂苷含量的测定方法，比较不同产地蒺藜品质差异。方法：以薯蓣皂苷元为对照品，采用紫外可见分光光度法测定蒺藜果中总皂苷的含量。结果：薯蓣皂苷元在0．00752-0．1504Ixg线性关系良好，回归方程：y=4．0439x＋0．1232，R。=0．9912，平均回收率为98．70％，RSD=2．8％。结论：不同产地蒺藜品质存在差异，河南产的蒺藜品质最佳。

Objective ： To establish the determination method of total saponins in Tribulus terrestris, then compare the quality differences among Tribulus terrestris from different areas. Methods：Diosgenin as reference, using UVvisible spectrophotometry to determine total saponins in Tribulus terrest＇s fruit. Results ： Diosgenin has good linear relationship in 0.00752-0.1504 pL g, the regression equation ： y=4.0439x ＋0.1232, R2=0.9912, average recovery was 98.70%, RSD= 2.8%. Conclusion：There are quality differences among different areas of Tdbulus terrestris, the best quality from Henan.
