In order to extract Hibiseu smanihot L. seed oil(HSO),response surface methodology was used to optimize the conditions of supercritical carbon dioxide extraction of Hibiseu smanihot L. seed oil. Based on single factor experiment,with extraction pressure,extraction temperature and extraction time as factors and yield of Hibiseu smanihot L. seed oil as index,the mathematical model was established by central composite experiment(Box-Behnken) for response surface analysis,and the fatty acid composition of Hibis...
