摘要

目的: 分离制备栀子药材中化学成分

建立栀子中该成分HPLC含量测定法。方法: 色谱条件采用Kromasil C18色谱柱(4.6 mm×250 mm

5 μm)

以乙腈-0.1%磷酸水溶液(18:82)为流动相

流速1.0 mL ·min-1

检测波长327 nm

柱温40 ℃。结果: 从栀子药材中分离鉴定出6"-对香豆酰京尼平龙胆双糖苷(1)

5-二-O-咖啡酰基-4-O-(3-羟基-3-甲基)戊二酰基奎宁酸(2)2个成分;这2个成分在0.118 8～1.188

0.122 8～1.228 μg线性关系良好;平均回收率分别为99.23%

100.4%

RSD分别为2.4%

2.3%;栀子不同采收期对2种成分含量影响较大。结论: 本试验结果能较好地反映栀子不同采收期成分的变化

可为栀子药材质量标准的完善提供参考。

Abstract

Objective: To prepare chemical constituents and establish an HPLC method for determining these constituents in Gardeniae Fructus. Method: The chromatographic separations were obtained on a Kromasil C18 column (4.6 mm×250 mm

5 μm) with the mobile phase consisting of acetonitrile and 0.1% phosphoric acid aqueous solution (18: 82) at a flow rate of 1.0 mL · min-1. The detection wavelength was set at 327 nm

and the column temperature was 40 ℃. Result: 6"-p-coumaroyl genipin gentiobioside(1) and 3

5-di-O-caffeoyl-4-O-(3-hydroxy-3-methyl) glutaroyl quinic acid(2) were isolated from Gardeniae Fructus. These two constituents showed good linear relationship in range of 0.118 8-1.188 μg and 0.122 8-1.228 μg

respectively. The average recoveries were 99.23%(RSD 2.4%) and 100.4%(RSD 2.3%). Harvesting time has significant effect on the contents of the two constituents. Conclusion: The tests reflect the variation of the constituents in different harvesting time and the methods established are suitable for the quality improvement of Gardeniae Fructus.
