多民族药东破石珠的生药学鉴定

目的：对多民族常用的植物药东坡石珠进行生药学鉴定,为其鉴别及应用提供科学依据。方法：采用原植物、性状、显微鉴别方法。结果：东坡石珠在原植物、性状、显微等具有专属性的特征。结论：通过原植物、性状、显微能够很好地鉴定东坡石珠。     

RP-HPLC法测定薏苡中薏苡素的含量

采用HPLC法,以Diamonsil(R)C_(18)为色谱柱,乙睛-水(50∶50)为流动相,流速1 mL/min,柱温25℃,检测波长232 nm,建立了薏苡非种仁部位中薏苡素的高效液相含量测定方法.结果表明:薏苡素在0.096～1.92μg范围内呈良好的线性关系,该方法的平均回收率为99.12%(n=5),相对标准偏差(RSD)为0.89%,用此条件测得成都华西植物园中薏苡全草中薏苡素的含量为8.3078 mg/g.从成分薏苡素和资源综合利用的角度考虑,建议薏苡根、茎和叶可以入药.

Abstract：

To establish an RP-HPLC procedure for determining the content of coixol in the root,stem and leaf of Coixlacryma-jobi L.var.mayuen(Roman.) Stapf. Methods The Diamonsil(R)C_(18) col-umn was used with the mobile phase of acetonitrile-water (50: 50), a flow rate of 1 mL/min, a tempera-ture of 25℃and a wavelength of 232 nm. Results The linear range of coixol was 0.096-1.92μg. The av-erage recovery was 99.12% (n=5, RSD is 0.89 %). Coixol in the herbal of C. Lacryma-jobi L. Var. Mayue in the Botanical Garden of West China was 8.3078 mg/g. Conclusion This method proved to be simple, accurate,well replicable, and suitable for the determination of C.lacryma-jobi L.var.mayuen(Roman.) Stapf.
