Optimization of processing technology of Momordicae Semen cream by Box- Behnken design-response surface methodology / 中草药

ABSTRACT

Objective To optimize the optimum processing technology of Momordicae Semen cream using Box-Behnken design-response surface method (BBD-RSM). Methods The overall desirability (OD) of indexes of the content of 3-O-β-D- glucuronic acid methyl ester, β-sitosterol, and oleanolic acid and the content of fatty oil in gypsogenin was comprehensively evaluated, and BBD-RSM with three factors and three levels was used to study the effect of baking temperature and time, and pressing time on the processing technology of Momordicae Semen cream. Results According to the experiment, the optimum processing conditions were optimized the baking time 1.68 h, the baking temperature 80 ℃, the pressing time 30 min, and the OD value was 0.777. Considering the actual situation, the optimum processing technology of Momordicae Semen was obtained by fine-tuning the baking time (A). That was, the baking time was 1.7 h, the baking temperature was 80 ℃, and the pressing time was 30 min. Also, the calculated OD values were 0.779, 0.783, 0.766, and its RSD was 1.15% through the obtained conditions in parallel with three batches of samples. Conclusion The processing technology optimized by Box-Behnken design-response surface method has the advantages of stable, good model prediction effect and a new processing technology for Momordicae Semen cream production.
