摘　　要：目的:优选掌叶大黄药材的最佳产地加工方法。方法:将大黄趁鲜切片加工,以晒干法、阴干法、微波法、不同温度烘干等不同方式干燥,其加工品的折干率、蒽醌衍生物含量及横切面质地和色泽变化与传统加工方法比较。结果:趁鲜切制对掌叶大黄药材折干率影响不大,但能明显降低蒽醌类成分含量,药材横切面色泽褐变明显;不同干燥方式以熏干法的蒽醌类成分含量、横切面色泽质量最好,阴干和微波法其次,80℃烘干最差。结论:掌叶大黄产地加工不宜趁鲜切片加工,干燥方式以传统的熏干法最好。Objective： To choose the optimum initial processing methods of Rheum palmatum.Methods： Fresh crude Rheum palmatum was sliced and dealt with the different drying methods such as sun drying,shady drying,microwave heating and various temperatures drying.The content of the Anthraquinones derivatives,slicing colors and dried rates were used as evaluation indexes.The sliced Rheum palmatum was compared with the traditional processing.Results： Sliced fresh crude Rheum palmatum had the low content of the Anthraquinones derivatives and dry rates,slicing colours had obviously changes.For various drying methods,smoking drying was superior to sun drying,shady drying,microwave heating and various temperatures drying methods.Conclusion： Fresh crude Rheum palmatum is not suitable for slicing processing.The best drying method is smoking drying.
