Abstract:
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 ≥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 references for evaluating the specifications and grades of traditional Chinese medicines.
