摘 要:目的:建立测定不同产地雷公藤药材中雷公藤内酯甲含量的方法。方法:采用高效液相色谱法。色谱柱为Welch material Inc C18(250mm×4.6mm.5μm),流动相为甲醇-0.1%磷酸溶液(含0.2%三乙胺)(85:15,V/V),检测波长为210nm,流速为1.0ml/min.柱温为25℃,结果:雷公藤内酯甲的进样量在0.20~2.00gg范围内与峰面积积分值呈良好的线性关系(r=0.9999);精密度、稳定性、重复性试验的RSD〈1%;平均加样回收率为97.86%,RSD=1.34%(n=6)。结论:该方法简便、准确、重复性好,适用于雷公藤药材及其制剂中雷公藤内酯甲的含量测定与质量控制。OBJECTIVE: To establish the method for the content determination of wilforlide in Tripterygium wilfordii from different producing area. METHODS: HPLC method was adopted. The determination was performed on Welch material Inc C18(250 mm×456 mm, 5 μm) column with mobile phase consisted of methanol-0.1% phosphate(containing 0.2% triethylamine, 85:15, V/V) at the flow rate of 1.0 ml/min. The detection wavelength was set at 210 nm, and the column temperature was 25 ℃. RESULTS: The linear range of wilforlide was 0.20-2.00 μg(r=0.999 9) with an average recovery of 97.86% (RSD= 1.34% ,n=6). RSDs of precision, stability and reproducibility tests were lower than 1%, CONCLUSIONS: The method is simple, accurate, reproducible and suitable for the content determination and quality control of wilforlide in 77 wilfordii and related preparations.
