为解决中药材色谱分析中对照品价格较高的问题,该文以金银花药材为例,提出采用对照提取物作为参考物质,对药材进行常规分析的方法。采用对照品对对照提取物进行了标定,测定出其中6种有机酸类化合物的含量,并考察了对照提取物的长期稳定性。利用对照提取物配制不同浓度的溶液,建立了标准曲线。对11批次金银花药材进行分析,采用t检验方法对分别利用对照品和对照提取物测得的结果进行比较,结果表明二者之间不存在显著性差异。该方法可用于金银花药材的质量控制,并对解决类似问题有借鉴意义。
In order to solve the problem of high price of reference substance in chromatographic analysis of Chinese herbal medicines, this paper takes honeysuckle as an example, and puts forward the method of routine analysis of medicinal materials by using the control extract as a reference material. The reference substance was used to calibrate the control extract, and the contents of six kinds of organic acid compounds were determined. The long-term stability of the control extract was also investigated. The control extract was used to prepare solutions with different concentrations, and a standard curve was established. 11 batches of honeysuckle herbs were analyzed using the t-test methods were compared with the reference substance and the control extract were compared, the results show that there is no significant difference between the two. The method can be used for quality control of honeysuckle medicinal materials and has reference significance for solving similar problems.
