Study on Extraction Method of Total Flavonoids in Chinese Herbal Medicine Helwingia Himalaica
摘要
Abstract
With the methods of the chemical qualitative detection and the spectral analysis,the categories of the total flavonoids in the whole plant of H.himalaica was researched,and effect of four factors（volume fraction of ethanol,temperature,ratio of solid-liquid,extraction time） on the efficiency of extraction of the total flavonoids was also evaluated by orthogonal design L9（34）.The results suggested that the total flavonoids consisted of flavones,flavonols,flavanones,flavanonols.The influencing degree of each factor on the efficiency was as follows： temperaturevolume fraction of ethanolratio of solid-liquidextraction time.The optimum extracting conditions are A1C3B2D3.The highest efficiency of extraction of the total flavonoids reached 1.479% under such optimal conditions.关键词
