Effects of Different Primary Processing Methods on the Quality of Corydalis Rhizoma
摘要
Abstract
Objective:To investigate the effect of external characters and internal components contents of Corydalis Rhizoma with different primary processing,and select the appropriate primary processing.Methods:The fresh Corydalis Rhizoma was treated by sun-drying,shade-drying,freeze-drying,hot air drying,far infrared drying and microwave drying methods,and the contents of seven alka-loids,including protopine,glaucine,tetrahydropalmatine,corydaline,palmatine hydrochloride,berberine hydrochloride,dehydrocorydaline were determined by HPLC.The color of powder was determined by color difference meter,the rehydration ratio,drying rate,extract con-tent and external appearance were analyzed.The influence of each method on the quality of medicinal materials was comprehensively evaluated by chemometry.Results:Corydalis Rhizoma treated by sun-drying had the best appearance and higher total alkaloid content,but it took a long time.The dry times of hot air drying and far infrared drying were significantly decreased,and when the temperature was 60 ℃,the appearance was similar to that of sun-drying,and the total alkaloid content was higher.Microwave drying method had the advantages of shortest time,highest total alkaloid content.The shade-drying process took the longest time,with lower total alkaloid con-tent and the poorest appearance.The freeze-dried herbs were light in weight,the internal texture was porous and loose,the content of to-tal alkaloids was lowest.Conclusion;The drying method of hot air at 60 ℃ can greatly improve the drying efficiency,ensure the charac-teristics of medicinal materials and the content of components,and can be used for large-scale processing of Corydalis Rhizoma.The mi-crowave drying has wide development prospects after the equipment improved.关键词
