Abstract

Alpinia officinarum Hance, one of the local herbs in Guangdong, has the rich content of flavonoids and is one of the most commonly used traditional Chinese medicines for the treatment of gastrointestinal tract regulation, smooth muscle spasmolysis, immunoloregulation, antioxygen, tumors, diarrhea, and diphenylheptanes. At present, the main extraction methods of Alpinia officinarum Hance is organic solvent extraction. To obtain the optimum extraction conditions of Alpinia officinarum Hance flavonoids, this study is on the basis of the references, using Ultraviolet spectrophotometric method to measure the content of flavonoids in Alpinia officinarum Hance to explore the ethanol concentration, extraction temperature, extraction time, the solid-liquid ratio and the extraction times in the effects of galanga flavonoids. The experiment found that the opimal extraction condions were as follows: the concentration of 40% ethanol, extraction temperature 70 , the solid-liquid ratio of 1:20, extraction time 3 h, extracting for 1 time. Under these conditions, the extraction rate of Alpinia officinarum Hance flavonoids could be as high as 1.40%, namely 14 mg/g.
