Abstract:
OBJECTIVETo optimize the herb processing process for the total contains of psoralen and isopsoralen and the rate of extract in Psoralea corylifolia by micro-wave herb processing.
METHODThe contains of psoralen and isopsoralen was obtained by HPLC. The micro-wave herb processing process was optimized by the way of uniform design and contour map.
RESULTThe optimum process was:20% as salt concentration, 4h as immerse time, micro-wave strength as strong, 270 seconds as micro-wave time. The absolute error of the predicted value from the models were smaller than 6% and 0. 3% respectively.
CONCLUSIONThe regression models are notable and reasonable, which can forecast results precisely.
