摘要:目的 建立HPLC 测定肾炎宁片中大黄酸、大黄素、大黄酚及雷公藤甲素的含量。方法 大黄酸、大黄素、大黄
酚的测定采用流动相为甲醇-0.1%磷酸(70 ∶30) ,检测波长为254 nm;雷公藤甲素采用流动相为乙腈-水(25 ∶75) ,检测波
1
长为220 nm;两者均采用Lichrospher-C18 柱(4.6 mm×250 mm ,5 m) ,流速均为1.0 mL·min 。结果 大黄酸、大黄素、
大黄酚以及雷公藤甲素分别在 1.83~14.64 μg·mL1(r=0.999 9) ,2.895~23.16 μg·mL1(r=0.999 8) ,7.625~61.00 μg·mL1
(r=0.999 8) 以及1.52~24.32 μg·mL1(r=0.999 6) 内与峰面积呈良好的线性关系,大黄酸平均回收率为103.2%,RSD=1.73%
(n=9);大黄素平均回收率为98.6% ,RSD=3.94%(n=9);大黄酚平均回收率为98.3% ,RSD=2.54%(n=9);雷公藤甲素平均
回收率为99.61% ,RSD=2.83%(n=9) 。结论 本方法准确、可靠、专属性强,可作为该制剂的定量控制方法。

ABSTRACT: OBJECTIVE To establish a quantitative method for parietic acid, emodin, chrysophanol and triptolide in
Shenyanning tablets by HPLC. METHODS The mobile phase for determining parietic acid, emodin, chrysophanol was
methanol-0.1% phosphoric acid(70 ∶30), the UV detection wavelength was 254 nm, while the mobile phase for triptolide was
acetonitrile-water (25 ∶75), the UV detection wavelength was 220 nm. Lichrospher C18(4.6 mm×250 mm, 5 m) column was
used for the determination, and the flow rate was 1.0 mL·min1. RESULTS The linear range of pariet
