摘要:目的提高归脾丸的质量标准。方法采用薄层色谱法对党参、炙黄芪、远志、当归进行鉴别;用高效液相色谱-蒸发光散射法测定黄芪中黄芪甲苷的含量,色谱柱为Diamonsil C18(4.6 mm×250 mm,5 μm);流动相为乙腈-水(32∶68);流速为1.0 mL·min-1,漂移管温度105 ℃,气体流量2.5 L·min-1。结果薄层色谱斑点清晰;黄芪甲苷在1.046 0~5.230 0 μg(r=0.999 8)的范围内线性良好,平均回收率为101.24%(n=6),RSD为1.92%。结论本法结果准确、可靠,可用于该制剂的质量控制。

Abstract:ObjectiveTo improve the quality standard of Guipi Pills for better controlling the quality of drugs.MethodsThe TLC was employed on Radix Astragali,honey-fried Radix Astragali,Radix Polygalae,Radix Angelicae Sinensis for identification;The content of astragaloside in Radix Astragali was determined by HPLC-ELSD.A Dikma Diamonsil C18 column(4.6 mm×250 mm,5 μm)was adopted with methanol-water(32∶68) as mobile phase at a flow rate of 1 mL·min-1.An eweaporative light-scattering detector (ELSD) Model 2000 was used with the drift tube temperature at 105 ℃ and the gas flow rate at 2.5 L·min-1.ResultsThe TLC chromatographic spots were clear;The linear range of astragaloside was 1.046 0~5.230 0 μg(r=0.999 8),the average recovery was 101.24%,and RSD=1.92%(n=6).ConclusionThe results showed that this method was accurate,reliable and can be used for the preparation of quality control.

归脾丸由党参、炒白术、炙黄芪、炙甘草、茯苓等15味中药组成,具有益气健脾,养血安神功效。用于治疗心脾两虚,气短心悸,失眠多梦,头昏头晕,肢倦乏力,食欲缺乏,崩漏便血等[1]。近年来发现,归脾丸对神经衰弱、窦性心动过缓及阵发性心动过速、冠心病、更年期综合征、缺铁性贫血、慢性苯中毒亦有较好的改善作用[2~4]。为有效控制本品质量,采用薄层色谱法(TLC)对处方主要药味党参、炙黄芪和远志进行定性鉴别,并用高效液相色谱-蒸发光散射法(HPLC-ELSD)测定黄芪中有效成分黄芪甲苷的含量[5],为全面控制产品质量提供依据。
