Abstract: The optimum extracting conditions of flavones in Schisandra chinensis(Turcz.)Baill leaves were investigated by single factor test with the orthogonal test design.The main factors affecting the content of total flavones extracted from Schisandra chinensis(Turcz.)Baill leaves were the material-liquid ratio,the extraction temperature,the extraction time and the alcohol concentration.The results showed that the optimum conditions were:85℃,60min,75% alcohol and material-liquid ratio 1:35. Under the conditions,the contents of total flavones in Schisandra chinensis(Turcz.)Baill leaves collected in both July and August are 6.0285mg/g and 8.0714mg/g,respectively.
Key words: Schisandra chinensis(Turcz.) Baill leaves, total flavones, optimum extracting process
