当归的等级化研究

中草药标准化是非常有必要的,需要用物理和化学的方法来建立标准.标准化的分级是每位草药生产的指标之-.中国当归的等级分为5级:大体、形状、颜色、香味及杂质是否存在.而韩国的生当归分为三级,分别是60 g以上,20～60 g之间,20 g以下.当归身的重量约占整个当归的30%,其表面颜色是浅黄棕色到褐色.-般没有次品.若有次品,多为腐烂、中空、表面色黑或中节呈褐色.提出了当归标准化的等级,并期待着进-步研究.此研究可以做为中药标准化研究的参考指标.

The study on the standardization of angelicae gigantis radix

It is necessary to standardize the medicinal herbs so that they can be used for medical treatments.Both physical and physicochemical methods are required to establish the standard.The classes of standardization about each herb medicine was one of the index instandardization of manufactures, the classes of standardization about angelicae gigantis radix were divided five grades in China accordingto whole sizes, shape, colors, fragrance, taste and existence and nonexistence of foreign substances.The raw Angelicae Gigantis Radix wasused for this study, on the basis of Chinese standardization about angelicae gigantis radix, I divided them into three grades.The first gradewas 60 g or more, the second one is 20 g or more, and the third one is less than 20 g.The ratio of weights of body/whole weights in allgrade angelicae gigantis radix was more than 30%.Their surfaces was from yellowish brown to dark brown.None inferior goods was found.The inferior goods was rotten or empty or black-surface or brown section.The result from this study can be suggested as the model of thestandardization and the standard for grading Angelicae Gigantis Radix.Also, I expected to do further study on the cut herb.Then this canbe the reference index of the standardization of Chinese of herbs.
