Optimization of processing technology for prepared Chuanxiong Rhizoma by D-optimal response surface methodology with comprehensive weighted of multi-index / 中草药

ABSTRACT

Objective: To optimize the processing technology for prepared Chuanxiong Rhizoma by D-optimal response surface methodology with comprehensive weighted of multi-index. Methods: The single factor experiment was used to optimize the dilution ratio and the moistened time of rice wine. Then, based on the contents of five main components (ferulic acid, ligustilide, senkyunolide A, senkyunolide I, and 3-butylidenephthalide), the D-optimal response surface methodology was used to optimize the rice wine dosage, stir-fried temperature, and stir-fried time in the processing technology for prepared Chuanxiong Rhizoma. Results: The optimal processing technology for prepared Chuanxiong Rhizoma was mixed with 20% rice wine, moistened for 75 min, and stir-fried for 12 min at 156 ℃. Also, it was found that the contents of senkyunolide A, senkyunolide I, and 3-butylidenephthalide in prepared Chuanxiong Rhizoma had increased, and it should be associated with processing. Conclusion: The processing technology for prepared Chuanxiong Rhizoma optimized by D-optimal response surface methodology with comprehensive weighted of multi-index can be used to optimize the process parameters, promote the stability and repeatability of the processing technology, which can significantly control the inner quality of prepared Chuanxiong Rhizoma to ensure effectiveness in clinical application.
