摘要

目的: 比较微波协助提取法与药典法提取欧前胡素优势。方法: 采用Dikma Diamonsil C18色谱柱(4.6 mm×150 mm

5 μm)

流动相为甲醇-水(55 ∶45)

检测波长300 nm

柱温30 ℃

流速1 mL·min-1。结果: 微波提取时间10 min

提取温度80 ℃

提取溶剂乙醇。欧前胡素在0.01~0.2 μg呈良好线性关系(r=0.999 9)。平均回收率97.48%(n=6)。结论: 微波提取法较药典法提取欧前胡素更简便快速、结果准确

为一种符合环保绿色理念的含量测定方法

可用于检测白芷药材中有效成分欧前胡素含量。

Abstract

Objective: To establish a microwave-assisted extraction method for the extraction of imperatorin from Angelica dahurica(Fisch.ex Hoffm.) . Comparison of the determination of imperatorin from A. dahurica between microwave-assisted extraction and Chinese pharmacopeia method was carried out. Method: Dikma Diamonsil C18 column (4.6 mm×150 mm

5 μm) was used. The mobile phase consisted of methanol-water (55 ∶45). The temperature of column was at 30 ℃. The flow rate was 1.0 mL·min-1 and the detection wavelength was at 300 nm. Result: Microwave extractive time was 10 min

the temperature was at 80 ℃

the extraction solvent was ethanol. The calibration curve was linear in the range from 0.01 to 0.2 μg (r=0.999 9). The average recovery was 97.48% (n=6). Conclusion: The method is simple

rapid

as well as precise and reliable

and can be used for the determination of imperatorin from A. dahurica.
