摘要
目的:建立同时测定裸花紫珠药材中木犀草素-7-O-β-D-吡喃葡萄糖苷、木犀草素、5,4'-二羟基-3,7,3'-三甲氧基黄酮和5-羟基-3,7,3’,4’-四甲氧基黄酮含量的反相高效液相色谱法。方法:采用HPLC,Venusil XBP-C18色谱柱(4.6mm×200mm,5μm),流动相甲醇.体积分数为0.1%磷酸水系统,梯度洗脱,流速1.0rnL·min-1,柱温室温,检测波长350nm。结果:在上述色谱条件下测得木犀草素-7-O-β-D-吡喃葡萄糖苷、木犀草素、5,4’-二羟基-3,7,3’-三甲氧基黄酮和5-羟基-3,7,3’,4’-四甲氧基黄酮的质量浓度分别在0.0008~0.016,0.0016~0.032,0.004~0.08,0.0024~0.048g·L-1时与色谱峰面积之间线性关系良好;平均回收率为98.5%(RSD1.7%),98.6%(RSD1.6%),98.6%(RSD1.4%),98.6%(RSD1.7%)。结论:该方法精密度高,重复性好,可用于裸花紫珠药材中木犀草素-7-O-β-D-吡喃葡萄糖苷、木犀草素、5,4’-二羟基-3,7,3’·三甲氧基黄酮和5·羟基-3,7,3’,4’-四甲氧基黄酮的含量测定。
Objective: To develop HPLC for the simultaneous determination of four flavonoids in Callicarpa nudiflora. Method: The separation was performed on a Venusil XBP-Clscolumn (4.6 mm x 200 mm, 5 μm), the analytes were separated efficiently using the mobile phase consisted of MeOH-H20 [ w (H3PO4) = 0.1% ] in a gradient program. The flow rate was maintained at 1.0 mL .min 1 The detective wavelength was set at 350 nm and the column temperature was 25 ℃ Result: There were good linear relationships between the concentrations and the peak area of luteolin-7-O-β-glucopyranoside, luteolin, 5, 4'-dihydroxy-3, 7, 3'- trimethoxyflavone and 5-hydroxy-3, 7, 3', 4'-tetramethoxyflavone in the ranges of 0. 000 8-0. 016 g . L-1 (r = 0.999 1), 0.001-0.032 g.L-1 (r=0.999 1), 0.004-0.08 g.L-1 (r=0.999 2), 0.002 4-0.048 g.L-1 (r= 0. 999 1 ) , respectively. The recoveries were found to be 98.5% with RSD of 1.7% (n = 9) , 98.6% with RSD ofl. 6% (n=9), 98.6% with RSD of 1.4% (n =9) and 98.6% with RSD of 1.7% (n =9), respectively. Conclusion: The method is accurate and reproducible for determination of luteolin-7-O-β-D-glueopyranoside, luteolin, 5, 4'-dihydroxy-3, 7, 3'-trimethoxyflavone and 5-hydroxy-3, 7, 3', 4'-tetramethoxyflavone in C. nudiflora.
