目的:对参地补肾接骨胶囊薄层鉴别和含量测定进行研究。方法:对处方中黄芪、当归、枸杞子进行定性鉴别;采用UV-HPLC法测定何首乌中2,3,5,4′-四羟基二苯乙烯-2-O-β-D葡萄糖苷含量。结果:黄芪、当归、枸杞子斑点清晰,阴性均无干扰,专属性强。2,3,5,4′-四羟基二苯乙烯-2-O-β-D葡萄糖苷在3.08~30.80μg·mL-1范围内线性关系良好(r=0.999 6),平均回收率为100.2%,RSD为1.83%。结论:该法操作简便、结果准确、重复性好,适用于参地补肾接骨胶囊的质量控制。
OBJECTIVE: To study the TLC identification and content determination of Bushen Jiegu capsule. Methods: Astragalus membranaceus, Angelica sinensis and Fructus Lycii were qualitatively identified in the prescription. The content of 2,3,5,4’-tetrahydroxystilbene-2-O-β-D-glucoside in Polygonum multiflorum was determined by UV-HPLC. Results: Astragalus, Angelica, medlar spots clear, negative no interference, specificity. The linearity of 2,3,5,4’-tetrahydroxystilbene-2-O-β-D-glucoside was good (r = 0.999 6) in the range of 3.08-30.80μg · mL-1 and the average recovery was 100.2 %, RSD is 1.83%. Conclusion: The method is simple, accurate and reproducible. It is suitable for quality control of Bushen Jiegu Capsule.
