Abstract:
Objective To screen the best processing technology of prepared Rhubarb by multi- component composite score combined with response surface.Methods The composite score of seven components, i.e., gallicacid, chrysophanol-8-O-β-D-glucopyranoside, aloeemodin, rhein, emodin, chrysophanol, physcion, was taken as indicators. Three factors and three levels of response surface Box-Behnken were used in experimental design. The effects of factors including rice wine volume, moistening time, and steaming time on processing technology of stewed Rhubarb were studied, and the optimized processing parameters were chosen.Results Design Expert 8.05 software was used for data analysis. Multivariate quadratic mathematical model of the sample and examine factors composite score regression equation of seven ingredients content were set up. The best processing conditions of prepared Rhubarb were as following:adding 36.6 mL rice wine into per 100 g raw material;moistening time continued for 2.16 hours;steaming time continued for 10.96 h. According to actual production, the optimized processing conditions of prepared Rhubarb are as following:adding 35 mL rice wine per into 100 g raw material;moistening time continued for 2 h;steaming time continued for 11 h.Conclusion The optimized processing technology can reasonably control the quality of prepared Rhubarb, and provide the basis for the quality standards of its decoction pieces and clinical application.
