提高坐珠达西质量标准的研究

Study on Enhancing the Quality Standard of Zuozhudaxi

摘要: 目的提高坐珠达西品种的质量标准。方法采用薄层色谱法对熊胆、牛黄、木香、丁香等主要药味进行了定性鉴别以及马钱子的液相鉴别，以高效液相色谱法对其主药西红花中西红花苷I进行含量测定。结果定性鉴别分离度好，专属性强；西红花苷I在0.031 62～0.284 58 μg范围内呈良好的线形关系，r=0.999 7(n=7)，平均回收率为 97.7%，RSD 为 1.55%(n=6)。结论本法可靠，准确，专属性强，可有效控制坐珠达西的质量。

Abstract: OBJECTIVE To enhance the quality standard of Zuozhudaxi. METHODS Thin-layer chromatography (TLC) was employed to identify Bear Gall,Calculus Bovis,Aucklandia lappa Decne, Syzygium aromaticum(L.) Merr.et Perry (Clove) and high performance liquid chromatography (HPLC) was applied for the identification of Semen strychni,while high performance liquid chromatography (HPLC) was applied for the determination of Crocin- I in Croci Stigma in Zuoxidazhu. RESULTS The identification by TLC and HPLC were distinct and highly specific. A linearity was obtained from 0.031 62 μg to 0.284 58 μg of Crocin-I in Zuozhudaxi with a good correlation (r=0.9997, n=6).The average recovery was 97.7%,and RSD was 1.55(n=7). CONCLUSION The method is reliable, accurate and specific and can be used for quality control of Zuozhudaxi.
