摘　　要：通过测量30批条芩饮片断面色泽指标和黄芩苷含量,计算二者的相关性,筛选出能表征条芩内在质量的色泽指标,并以此为基础,建立一种新的条芩饮片等级划分方法。结果表明,同时满足ΔL≥-37,Δb≥45的条芩饮片,是为选装,其黄芩苷量一定≥200 mg·g-1;与上述2指标其中之一不符者,均为统货。研究表明指标ΔL和Δb能够同时表征饮片色泽和内在质量,能够准确简便并客观的划分条芩饮片等级。研究结果可为中药饮片的分级提供新的思路和参考。By determination the section color and lustre indexes as well as the content of baicalin in 30 batches of Scutellariae Radix slices, calculate the correlation of these two, screen the color and lustre indexes which could represent their intrinsic quality, and es- tablish a new grade classification method based on the results. The results showed that samples met the conditions of △L ≥ - 37, △b ≥45 simultaneously were picked grade and the content of baicalin was of ≥200 mg g- 1 definitely; Samples inconsistent with any one of above conditions were general grade. This research indicated that indexes of AL and AD could characterize both the color and luster of slice and intrinsic quality, so that could be used as the indexes to classify the grades of Scutellariae Radix slices accurately, easily and objectively. The research results would provide new ideas and references for grade classification of traditional Chinese medi- cine slices.
