ABSTRACT
Objective To study the processing method,extraction technology and quality evaluation analysis of Paeonialactiflora Pall, so as to provide reference for selecting the best method and improving its quality .Methods One year and 3 years Chinese herbal medicine Paeonialactiflora Pall was used.The use of raw materials and cooked products for processing methods to paeoniflorinas the representative , and the content was determined by high performance liquid chromatography.With the optimization of orthogonal test, the methods for the determination of effective components of radix paeoniaealba were summarized and the quality control methods were analyzed .Results The content of paeoniflorin in raw paeonialactiflora pall was (6.33 ±0.52)%,and the content of paeoniflorinin cooked Paeonialactiflora Pall was (5.74 ±0.45)%, which was with statistical significance(P <0.05).The content of paeoniflorin in raw paeonialactiflora pall was (5.90 ±0.38)%,and 4.85 ±0.45% in three years cooked paeonialactiflora pall, and the differenceswere with statistical significance(P<0.05).Extracted three times with 70% ethanol, time 65 min, 6 times the amount of solvent,the paeoniflorin high cream rate was highest.By means of induction, several active ingredients should be screened out to control the content of paeonialactiflora pall to publish multiple indicatorsquality control methods .Conclusion The preparation method of Chinese herb paeonialactiflora pall has showed that the active ingredient content is morein raw herb.To establish quality control method of multiple indicators of paeonialactiflora pall based on raw herb,gradually improve the quality of more comprehensive paeonialactiflora pall quality control model.To optimize the extraction of Chinese herbal medicine,provide scientific reference for the sustainable utilization and industrial production of paeonialactiflorapall.
