Optimum Simmering Radix Puerariae with Wheat Bran Technology by Multi-index Orthogonal Experiment / 中国中医药信息杂志

ABSTRACT

Objective To optimize the processing technology for Radix Puerariae simmered with wheat bran.Methods Orthogonal experiment L9(34) was chosen to optimize the technology. The external properties of Radix Puerariae simmered by wheat bran, the content of puerarin and the antidiarrheal effect on mice with diarrhea caused by folium sennae were used as indexes. Comprehensive weighted score was employed to optimize simmering Radix Puerariae with wheat bran technology.Results Processing time was the main affecting factor, while processing temperature had no significant effect. The optimum processing parameters were 100 g Radix Puerariae simmered with 30 g wheat bran at 160℃ for 2 minutes.Conclusion The optimum processing technology was simple and convenient, and with good reproducibility and operability. It is also helpful for the quality control of Radix Puerariae simmered with wheat bran.
