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.
目的
选择大黄的最佳初加工方法。
方法
将新鲜大黄原药材切片后，采用晒干、阴干、微波加热及不同温度烘干等不同干燥方法处理。以蒽醌衍生物含量、切片色泽及干燥率为评价指标。将切片后的大黄与传统加工方法进行比较。
结果
新鲜大黄原药材切片后蒽醌衍生物含量及干燥率较低，切片色泽有明显变化。对于各种干燥方法，熏干优于晒干、阴干、微波加热及不同温度烘干方法。
结论
新鲜大黄原药材不适于切片加工。最佳干燥方法为熏干。
