| Abstract: | Through extracting Total Flavanone of Polygonum aviculare L the micro scale chemical experiments （constant pressure separating funnel） compared with the traditional method （supersonic wave and apparatus）, a new method based on the micro scale chemical experiments compared with the traditional method ,the new method have the characteristics of less pollution, small sample volume and save time. Micri chemical experiments are good ones that are acceptable . Using spectrophotome try to extract and check the flavanone of polygonum aviculare L. Extracting Total Flavanone of Polygonum aviculare L the micro scale chemical experiments, measure sample in average content of the total flavonoid is 1.96%, average recovery rate is 101%. |
