摘要
本文采用水提法、有机溶剂提取法、超声波提取法提取水母雪莲花中黄酮化合物.以芦丁为对照品,对其进行络合显色,用紫外及可分光光度法测定水母雪莲粗提物中总黄酮的含量,回归方程为A=1.20932C-0.07937,r=0.9973.3种提取方法相比,超声波提取法提取总黄酮的含量高,更容易实现产业化生产.
This article reviews the technology on extraction of water and extraction of orgnic solvent and extraction of rhapontinum.the three technology extract the flavones compounds from Saussurea medusa Maxim.The flavones was reference standard and the concertration of flavones was determined by UV spectrophotometer,then found the equation of curve is A=1.20932C-0.07937,r=0.9973.By contrast the three technology,the extraction of rhapontinum is better than those technology and can be easily reached.
