摘要: 探讨高效液相色谱法同时测定通宣理肺颗粒中黄芩苷和柚皮苷的含量。方法:色谱柱:Agilent HC-C18 ( 4.6 mm×250 mm,5 μm );流动相:乙腈:0.1%磷酸 ( 22:78 );流速:1.0 mL?min-1;柱温:25 ℃;检测波长:281 nm;进样量:10 μL。结果:黄芩苷和柚皮苷分别在0.359-5.322 mg?mL-1和0.156-2.408 mg?mL-1范围内呈良好的线性关系。测定通宣理肺颗粒中黄芩苷和柚皮苷的含量分别为2.7225 mg?g-1和0.7963 mg?g-1。黄芩苷平均回收率95.58%,RSD为1.56%;柚皮苷平均回收率94.26%,RSD为1.68%。结论:本方法简单方便、准确可靠、专属性强,可用于通宣理肺颗粒药物的质量控制。

Abstract: To established a HPLC method for the determination of baicalin and naringin in Tongxuan Lifei particles. The HPLC analysis was carried out on Agilent HC-C18 ( 4.6 mm × 250 mm, 5 μm ) chromatographic column; the mobile phase was conisited of acetonitrile 0.1% phosphoric acid aqueous solution ( 22:78 ); the flow rate was 1.0 mL?min-1; the temperature was 25 ℃; the detection wavelength was 281 nm; the sample loading volume was 10 μL. The linear range of baicalin was 0.359-5.322 mg?mL-1 and naringin was 0.156-2.408 mg?mL-1, respectively. The content of baicalin and naringin in Tongxuan Lifei particles were 2.7225 mg?g-1 and 0.7963 mg?g-1. Baicalin average recovery was 95.58% (RSD = 1.56%), and naringin average recovery was 94.26% (RSD = 1.68%). The method is simple, convenient, accurate and reliable, and it can be used to control thequality of Tongxuan Lifei particles.
