摘　　要：质量常数评价方法是一种基于传统又优于传统的综合性中药饮片等级评价方法,该文基于质量常数评价方法建立了黄柏饮片等级划分的模式。研究结果显示15批不同质量的黄柏饮片其相对质量常数范围为0.41~0.96。如果把黄柏饮片划分成3等级,则:一级黄柏饮片相对质量常数≥0.77;二级黄柏饮片相对质量常数<0.77且≥0.48;三级黄柏饮片相对质量常数<0.48。该研究表明,质量常数评价方法能够科学、合理、客观、准确的划分黄柏饮片等级,同时为皮类药材或饮片的等级划分提供了有益的参考。Quality constant is a comprehensive grades evaluation method for traditional Chinese medicine decoction pieces, which is better but based on traditional way. In this paper, a new grading mode for Phellodendri chinensis pieces was established based on quali- ty constant evaluation method. The results showed that the range of relative quality constant for 15 batches of different samples was from 0.41 to 0. 96. As customary, if these samples were divided into three grades： the relative quality constant shall be ≥0.77 for first grade ; 〈0. 77 but ≥0.48 for the second grade; and 〈0.48 for the third grade. This research indicated that the quality constant mode can be used to effectively grade the P. chinensis pieces in a scientific, reasonable, objective and specific way. Simultaneously, it pro- vided a beneficial reference for grading cortex herbal pieces or medicines.
