摘要
目的完善丛菔的质量标准。方法采用对口药材的采集、TLC鉴别、HPLC法测定含量的方法。结果 TLC法专属性强;在HPLC定量分析中,精氨酸的线性范围为0.0695～1.388μg(r=0.9997),平均回收率为98.02%,RSD=1.0%。结论所用方法操作简便、结果准确、重复性好,可作为丛菔药材的质量控制方法。
OBJECTIVE To improve the quality standard of Solms-Laubachiae Radix.METHODS The authentic ingredients were collected,and then identified and assayed by TLC and HPLC,respectively.RESULTS The TLC method was suitable and specific.A good linear relationship between the peak areas and injected amounts of arginine was obtained in the range of 0.0695-1.388 μg,the average recovery was 98.02%,and the RSD was 1.00%.CONCLUTION The method is simple,accurate,reproducible and can be used as the quality control of Solms-Laubachiae Radix.
