Thinking and Practice of the Classification of Fupian (Heishunpian)on the Basis of the Concept of Three-Step

Abstract:

Objective: According to the regulations about quality requirements and the experience of traditional classification of Chinese medicine Yinpian, combined with the modern testing technology, an innovative concept of Yinpian classification was put forward with Fupian (Heishunpian) selected for model practice. Method: Twenty batches of Heishunpian of different origins were graded according to the principle of 'three-step' hierarchical concept. The first step:the indicators of pharmacopoeia, such as traits, inspection, content determination and so on were adopted to determine the general level; the second step:size (length, width) and color (outer color E*_ab, inner color E*_ab) were employed to determine the first level; the third step:the geoherbalism and the more advanced inspection items were adopted as indicators to determine the best level. Result: Use of the research ideas and methods of classification, 3 batches of samples were removed from 20 batches because of its disqualification. Three levels were divided:2 batches were the best level; 7 batches were the first level; 8 batches were the general level. Conclusion: In this paper, the thought of Yinpian's classification and methods could divide the level of Heishunpian, and provide a basis for the classification of other varieties of Heishunpian and a reference for the thought of classification and technique of traditional Chinese Yinpian.
