基于质量常数法的合欢皮饮片等级评价

Grade Evaluation of Albiziae Cortex Decoction Pieces Based on Quality Constant Method

将质量常数评价方法应用于合欢皮饮片的等级评价中,对所收集的12批合欢皮饮片进行形态指标及成分指标测量,计算各样品的质量常数,并基于百分质量常数对样品进行等级划分。计算12批合欢皮饮片质量常数处于0. 041~0. 167;若以百分质量常数≥80%为一等饮片;<80%且≥50%为二等饮片;<50%为三等饮片,则一等合欢皮饮片质量常数≥0. 133 6,二等合欢皮饮片质量常数应为≥0. 083 5且<0. 133 6,三等合欢皮饮片质量常数<0. 083 5。笔者将皮类饮片质量常数评价方法进一步应用于合欢皮饮片的等级评价,证实该方法具有一定的合理性和科学性,可为该饮片的质量等级划分提供参考。

The quality constant evaluation method was applied to the grading evaluation of Albiziae Cortex decoction pieces.The morphological and component indexes of 12 batches of the decoction pieces were measured,their quality constants were calculated and graded.The results showed that the quality constant ranged from 0.041 to 0.167.If the percentage quality constant≥80%was the first-grade decoction pieces,<80%and≥50%was the second-grade decoction pieces,<50%was the third-grade decoction pieces;the quality constant of the first-grade decoction pieces was≥0.133 6,the second-grade decoction pieces was≥0.083 5 and<0.133 6,and the thirdgrade decoction pieces was<0.083 5.In this paper,the authors further applied the quality constant evaluation method of skin piece in the grading evaluation of Albiziae Cortex decoction pieces,which proved that the method was reasonable and scientific,and it can provide a reference for the quality grading of this decoction pieces.
