     摘要建立了测定莲芝消炎胶囊中穿心莲内酯含量的HPLC法。色谱条件为：Diamonsil-C18柱，ψ(甲醇∶水)=60∶40为流动相，流速0.8 mL/min，检测波长225 nm，柱温为室温。穿心莲内酯在43.6～261.6μg/mL浓度范围内与峰面积呈良好的线性关系(r=0.9998)，平均回收率98.1%，RSD=1.98%。

    Determination of the andrographolide in Lianzhixiaoyan capsules by RPHPLC

    Abstract A RPHPLC method for the determination of andrographolide in Lianzhixiaoyan capsules was established. A Diamonsil C18 column was used，with the mobile phase of methanolwater(60∶40). The flow rate was 0.8 mL/min, and the detection wavelength was 225 nm. The concentration of andrographolide was linearly related to its peak area in the range of 43.6～261.6μg/mL ......
