Abstract: The traditional Chinese medicine(TCM) quality constant herbal slices evaluation method was applied to evaluate the grade of Sophorae Tonkinensis Radix et Rhizoma based on the combination of traditional character identification and modern scientific and technological methods. The TCM quality constant evaluation method was used to determine the appearance and index content of medicinal slices, calculate the quality constant and percentile quality constant of Sophorae Tonkinensis Radix et Rhizoma from different sources, and discuss their classification. The quality constants of 15 batches of Sophorae Tonkinensis Radix et Rhizoma slices were between 0.004 and 0.063. The slices with the percentage quality constant ≥80% were classified as the first grade; those with the percentage quality constant ≥50% and <80% were classified as the second grade; and those with the percentage quality constant <50% were classified as the third grade. Then the slices with the quality constant ≥0.050 were classified as the first grade; those with the quality constant ≥0.032 and <0.050 were classified as the second grade; and those with the quality constant <0.032 were classified as the third grade. According to the results, the 15 batches of Sophorae Tonkinensis Radix et Rhizoma slices were divided into 1 batch of the first grade, 4 batches of the second grade, and 10 batches of the third grade. The quality constant evaluation method established is scientific, objective, simple and feasible. The application of the method in Sophorae Tonkinensis Radix et Rhizoma slices has reasonable results, which is helpful to promote the classification of Sophorae Tonkinensis Radix et Rhizoma and promotes the high-quality application of Sophorae Tonkinensis Radix et Rhizoma.
