摘要
目的:建立微波协助提取法提取骨碎补中有效成分柚皮苷含量测定方法,比较微波协助提取法与药典法提取柚皮苷优势。方法:采用Dikma Diamonsil C18色谱柱(4.6 mm×150 mm,5μm),流动相为甲醇-醋酸-水(35:4:65),检测波长283nm,柱温30℃,流速1 mL.min-1。结果:微波提取时间5 min,提取温度120℃,提取溶剂50%甲醇。柚皮苷在0.04～0.6μg呈良好线性关系,r=0.999 9。平均回收率99.51%(n=6)。结论:微波提取法较药典法提取柚皮苷更简便快速、结果准确,为一种符合环保绿色理念的含量测定方法,可用于检测骨碎补饮片中有效成分柚皮苷含量。
Objective： To establish a microwave-assisted extraction method for the extraction of the naringin from Drynaria fortunei, and compare of the determination of naringin from D. fortunei between microwave- assisted extraction and Chinese pharmacopeia method. Method： Dikma Diamonsil Cls column （4.6 mm ×150 mm, 5μm） was used. The mobile phase consisted of methanol-acetic acid-water （35：4： 65）. The temperature of column was mainted at 30 ℃. The flow rate was 1.0 mL·min-1 and the detection wavelength was at 283 nm. Result： Microwave extractive time was 5 rain, the temperature was 120℃, the extraction solvent was 50% methanol. The calibration curve was in good linearity with in the range from 0.04 to 0.6 μg （r = 0. 999 9）. The average recovery was 99.51% （n = 6）. Conclusion： The method is simple, rapid, as well as precise and reliable, and can be used for the determination of naringin from D. fortunei.
