薜荔叶及花序托中总黄酮的提取工艺

Using orthogonal test, a systematic study was carried on the extraction technology of total flavonoides from the leaves and the receptacle of inflorescence of \%Ficus pumila \%L., favourable parameters of this technology were selected out. The best conditions to extract total flavonoides are: 1∶40 ethanol solution of 70%, at 70～75℃ for four hours. Under the same condition, more total flavonoides can be extracted from leaves than receptacle of inflorescence. The effects of different reagents on total flavonoid extracting are also reported.
