摘要

目的: 建立微波协助提取法提取野菊花中有效成分蒙花苷含量测定方法

比较微波协助提取法与药典法提取蒙花苷优势。方法: 采用Dikma Diamonsil C18色谱柱(4.6 mm×150 mm

5 μm)

流动相甲醇-水-冰醋酸(26∶23∶1)

检测波长334 nm

柱温30 ℃

流速1 mL·min-1。结果: 微波提取时间15 min

提取温度100 ℃

提取溶剂50%乙醇。蒙花苷在0.04~1.2 μg呈良好线性关系(r=0.999 9)

平均回收率100.13%(n=6)。结论: 微波提取法较药典法提取蒙花苷更简便快速、准确

为一种符合环保绿色理念的含量测定方法

可用于检测野菊花饮片中蒙花苷含量。

Abstract

Objective:To establish a microwave-assisted extraction method for the extraction of the linarin from Chrysanthemun indicum. Comparison of the determination of linarin from C. indicum between microwave-assisted extraction and Chinese pharmacopeia method was made. Method: Dikma Diamonsil C18 column(4.6 mm×150 mm

5 μm)was used. The mobile phase cousisted of methanol-water-acetic acid (26∶23∶1).The temperature of column was kept at 30 ℃. The flow rate was 1.0 mL·min-1 and the detection wave-length was at 334 nm. Result: Microwave extractive time was 15 min

the temperature was 100 ℃

the extraction solvent was 50% ethanol. The calibration curve was in good linearity within the range from 0.04 to 1.2 μg(r=0.999 9). The average recovery was 100.13%(n=6). Conclusion: The method is simple

rapid

as well as precise and reliable

and can be used for the determination of linarin from C. indicum.
