婦科養(yǎng)坤丸的質(zhì)量標(biāo)準(zhǔn)研究
【摘要】 目的建立婦科養(yǎng)坤丸的質(zhì)量標(biāo)準(zhǔn),以更好控制產(chǎn)品質(zhì)量。方法采用薄層色譜(TLC)法鑒別黃芩、木香、延胡索、甘草,以HPLC法測定黃芩苷的含量。結(jié)果TLC法可檢出黃芩、木香、延胡索、甘草,斑點(diǎn)清晰,陰性對照無干擾,專屬性強(qiáng)。黃芩苷在0.0576~1.44 μg范圍內(nèi)線性良好(r=0.999 9),平均加樣回收率為97.85%,RSD為0.86%。結(jié)論實(shí)驗(yàn)方法定性、定量方法簡便、可靠、準(zhǔn)確,可用于婦科養(yǎng)坤丸的質(zhì)量控制。

Abstract:ObjectiveTo establish the quality standard for Fukeyangkun Pills. MethodsRadix Scutellaria,Radix Aucklandiae,Rhizoma Corydalis and Radix Glycyrrhizae in the pills were identified by TLC. Baicalin content was determined by HPLC.ResultsRadix Scutellaria,Radix Aucklandiae,Rhizoma Corydalis and Radix Glycyrrhizae could be identified by TLC, the spots were clear with non-interference. The baicalin content could be determined by HPLC. The quantitative method of baicalin showed a good linearity in the range of 0.0576μg~1.44μg. The average recovery of Baicalin was 97.85%,and RSD was 0.86%,respectively. ConclusionThe method is simple,reliable,accurate and can be used for the quality control of Fukeyangkun Pills.
