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

5 μm)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 4~3.544 μg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。

Abstract

Objective:To investigate the relationship between the amount of water-soluble components of gastrodia and the boiling time. Method: A phenomenex C18 (4.6 mm×250 mm

5 μm) 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·min-1. The detection wavelength was set at 220 nm. Result: The linear range of gastrodin was 0.354 4-3.544 μg (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.
