Evaluation on processing technology for bran-fried Paeoniae Alba Radix by multi-index comprehensive weighted mark method / 中草药

ABSTRACT

Objective: To optimize the best processing technology for bran-fried Paeoniae Alba Radix (PAR). Methods: Taking the contents and extract yields of paeoniflorin, oxypaeoniflorin, albiflorin, and gallic acid in PAR as the indexes, the affecting factors on the processing technology of bran-fried PAR was investigated by orthogonal design test and multi-index comprehensive weighted mark method. Results: The best processing technology was to add 10% bran and fry for 8 min at 200°C. Conclusion: The optimal processing technology is stable, and could provide the references for the further study of PAR.
