| Abstract: | The objective of this study was to optimize extraction technology of total flavonoids from Alpinia officinarum Hanee with ethanol extraction method. Based on single - factor test, the orthogonal test was carried out. The results showed that the optimal extraction conditions of total flavonoids were deter- mined to be： ethanol concentration 50%, extraction temperature 60℃, solid to liquid ratio 1：20, and extraction time 1.5 h. Under these conditions, the extraction yield of total flavonoids form Alpinia offtcinarum Hance was 93.8 mg/g. |
