【摘要】 目的建立薄层扫描法测定新风胶囊中黄芪甲苷含量的方法。方法采用氟仿-甲醇-水(65: 35:10)10℃以下放置过夜的下层溶液作为展开系统,10％硫酸显色,测定波长λ=510 nm,薄层扫描。结果黄芪甲苷在1．012-5．060 μg范围内线性良好,r=0．999 1,平均回收率为96．7％,RSD=2．18％。结论本法快捷、简便、准确,可用于该制剂质量的控制。更多还原

【Abstract】 Objective To establish a method for the determination of astragaloside Ⅳ in xinfeng capsule by TLC-scanning. Methods The mobile phase is chloroform-methanol-water(65 : 35 : 10) below 10℃, and the plate was scanned at 510nm by the CAMAG Scanner-3.Results The calibration curve was linear in the range of 1.012-5.060 μg, r = 0.999 1, the average recovery was 96.7 % , RSD = 2.18%. Conclusion The method was quick, simple, accurate and suitable for the content determination of astragaloside Ⅳ in xinfeng capsule.更多还原
