Abstract:
Grade of Chinese medicine slices is the most clear and most direct way to characterize the quality of Chinese medicine slices,also the basis of realizing " good quality and good prices",and it can guarantee the industry health development. Therefore,grade evaluation of Chinese medicine slices( GECMS) is highly valued and has grown rapidly in the industry. In recent years,due to the comprehensive and measureable features,the Chinese medicine quality constant evaluation method has been gradually recognized and applied.The paper is to establish a method of grades evaluation of Glycyrrizae Radix et Rhizoma Praeparata Cum Melle( GRRPCM) based on the Chinese medicine quality constant. 20 batches of samples were collected from Chinese herbal slices enterprises and 14 batches of qualified samples were selected to determine their external morphological indexes and inner quality indexes,then their Chinese medicine quality constants were calculated and the grades were determined. The results revealed that the relative quality constant of these samples ranged from 0. 70 to 14. 08,with a percentage quality constant from 4. 95 to 100. 00. If these samples were divided into three grades: the relative quality constant shall be ≥11. 27 or percentage quality constant ≥80. 03 for the first grade; the relative quality constant shall be <11. 27 but ≥7. 04,or percentage quality constant <80. 03 and ≥49. 99 for the second grade; while for the third grade,the relative quality constant shall be <7. 04 or the percentage quality constant <49. 99. This research indicates that Chinese quality constant can be used to objectively grade the herbal slices,providing reference for grades standard development of complex processing slices. In addition,the connotation of GECMS that has evaluate the mass discrepancy is discussed for expanding application.
