摘要
目的:探讨天麻水溶性成分的煎出量与煎煮时间的关系。方法:采用高效液相色谱法,phenomenex C18(4.6 mm×250 mm,5μm)色谱柱,流动相乙腈与0.2%磷酸,梯度洗脱,流速1 mL.min-1,检测波长220 nm。结果:天麻素在0.354 4~3.544μg线性关系良好(r=0.999),平均回收率为99.4%,RSD 1.2%,天麻在煎煮3 h时天麻素等6个主要成分的煎出量最大。结论:天麻药材的最佳煎煮时间为3 h,与传统要求的久煎相吻合。
Objective: To investigate the relationship between the amount of water-soluble components of gastrodia and the boiling time. Method: A phenomenex Cts (4.6 mm x 250 mm, 5 Ixm) column was adopted. The mobile phase consisted of acetonitrile (A) and 0.2% phosphoric acid solution (B) in gradient elution mode. The flow rate was 1.0 mL ~ rain-' The detection wavelength was set at 220 nm. Result: The linear range of gastrodin was 0. 354 4-3. 544 p,g (r 〉 0. 999). The average recovery was 99.4% , RSD 1.2%. The maximum amounts of six major components including gastrodin were decocted 3 hours. Conclusion: The best time of decoction of Gastrodiae Rhizoma was 3 hours, consistent with traditional requirements.
