通过优化当归趁鲜切制工艺，明确清洗时间对当归有效成分含量的影响，为产地鲜当归干燥和全归片趁鲜切制提供参考。根据《中华人民共和国药典》(2020版)检测要求，检测不同清洗时间、不同干燥时间、不同干燥温度对鲜当归有效成分含量的影响，探究当归产地趁鲜切制对全归片质量的影响。结果表明，鲜当归清洗时间为3 min时能最大程度减少当归中有效成分流失。40 ℃热风干燥8 h后当归外观形态最好，阿魏酸、浸出物、挥发油含量较《中华人民共和国药典》(2020)规定分别高68.00%、21.49%、40.00%；与传统熏制棚熏干处理相比，阿魏酸含量高20.00%、浸出物含量高2.76%，挥发油含量高19.15%。综上所述鲜当归最佳干燥工艺为清洗时间3 min，40 ℃热风干燥8 h；全归片趁鲜切制最适工艺为清洗时间3 min，切片厚度3~5 mm，40 ℃热风干燥6 h。

This paper optimizes the fresh-cutting process of Angelica sinensis and clarifies the effect of washing time on the content of active ingredients in A. sinensis so as to provide a reference for drying fresh A. sinensis and the production of whole slices at the place of origin. According to the testing requirements of the People's Republic of China Pharmacopoeia(2020 edition), the effects of different washing times, drying durations, and drying temperatures on the active ingredients of fresh A. sinensis were evaluated, and the influence of the fresh-cutting process on the quality of whole slices at the place of origin was analyzed. Results showed that the loss of active ingredients in A. sinensis could be minimized when the cleaning time was 3 min. After 8 hours of drying at 40 ℃ with hot air, the appearance of A. sinensis was the best, ferulic acid, extractable matter, and volatile oil contents were 68.00%, 21.49%, and 40.00% higher, respectively, than those specified in the Pharmacopoeia(2020). Compared with the traditional drying treatment in the smoking shed, ferulic acid content increased by 20.00%, extractable matter by 2.76%, and volatile oil by 19.15%. In conclusion, the optimal drying process for fresh A. sinensis is washing for 3 minutes followed by hot-air drying at 40 ℃ for 8 hours, the optimal fresh-cutting process for whole slices involves washing for 3 minutes, slicing to 3 to 5 mm thickness, and hot-air drying at 40 ℃ for 6 hours.
