以质量常数为核心的黄芩饮片等级评价研究

Grades evaluation of Scutellariae Radix slices based on quality constant

通过测量22批黄芩饮片形态指标和成分指标,计算质量常数,建立一种新的黄芩饮片规格等级评价方法。黄芩饮片的质量常数范围是0.04~0.49,可以根据实际需要划分若干等级,如果划分为3个等级,则一级黄芩饮片质量常数≥0.39;二级黄芩饮片质量常数<0.39且≥0.24;三级黄芩饮片质量常数<0.24。研究表明质量常数能够同时表征外观形态和内在质量,是综合性等级评价指标,能够量化的、明确的、客观的划分商品规格等级。该文研究结果为中药商品规格等级的划分提供新的思路和参考。

By measuring the morphological indexes and the marker components content of 22 batches of Scutellariae Radix slices as well as calculating the quality constant, this research was aimed to establish a new method of evaluating the specifications and grades of Scutellariae Radix slices. The quality constants of these samples were in the range of 0.04-0. 49, which can be divided into several grades based on the real requirement. If they were divided into three grades, the quality constant was t〉 0. 39 for the first grade, 〈0. 39 but ≥0. 24 for the second grade, and 〈0. 24 for the third grade. This work indicated that the quality constants characterizing both apparent parameters and intrinsic quality can be used as a comprehensive evaluation index to classify the grades of traditional Chinese medicine quantitatively, clearly and objectively. The research results in this paper would provide new ideas and refer- ences for evaluatin; the specifications and grades of traditional Chinese medicines.
