对复方降脂胶囊进行了定性定量研究。显微方法鉴别红花；薄层色谱法对照药材鉴别决明子； ＨＰＬＣ法测定芍药苷的含量，十八烷基硅烷键合硅胶为固定相，甲醇－５ｍｍｏｌ／Ｌ柠檬酸水溶液一异丙醇（２５： ７５：２）为流动相，紫外检测波长 ２４０ ｎｍ，芍药苷与其它杂质得到有效分离。回收率为１００．５２％，ＲＳＤ＝１．９２％，测定结果所用药材赤芍中芍药苷的含量为４．４６％，三批样品的平均含量为 １２. ６９ ｍｇ／ｇ，暂定芍药苷的含量在 １０.１４ ｍｇ／ｇ以上。
Qualitative and quantitative study of compound lipid-lowering capsules was conducted. Identification of safflower by microscopic methods; identification of cassia seed by thin layer chromatography; determination of paeoniflorin content by HPLC, octadecylsilane bonded silica gel stationary phase, methanol-5mmol/L citric acid aqueous solution-isopropanol (25 : 75:2) for the mobile phase, UV detection wavelength 240 nm, peonidine and other impurities are effectively separated. The recovery was 100.52%, RSD=1.92%. The determination results were as follows: the content of paeoniflorin in Radix Paeoniae Rubra was 4.46%, the average content of three batches was 12.69 mg/g, and the Paeoniflorin was tentatively determined. The content is more than 10.14 mg/g.
