Quality analysis of Corydalis Rhizoma from different producing areas
Objective To analyze the quality of Corydalis Rhizoma based on the growth index and yield quality of Corydalis Rhi-zoma from different places.Methods The growth indexes and yield parameters of Corydalis Rhizoma plants were determined dur-ing the growth period,and the contents of total ash,alcohol soluble extract and Corydalis Rhizoma ethyl were determined after harvest according to the requirements of Chinese Pharmacopoeia(2020 edition).Results Chenggu County had the best tuber and plant growth,the highest yield was 7492.55kg/hm2,the best quality,the highest alcohol soluble extract content(27.5％),the highest ethyl rhizome content(0.185％),the alcohol soluble extract content and ethyl rhizome content were significantly higher than other producing areas.The total ash content in Chenggu County was the lowest(2.7％),which was significantly lower than other producing areas,followed by Kang County,and the worst in Xihe County.Conclusion The yield and quality of corydalis produced in Chenggu County are the best.
