Abstract:

The study aimed to conduct a comprehensive study on the quality requirements for Knoxiae Radix processed with vinegar and to offer technical support for the formulation of the standard of Shandong Province Chinese herbal medicine processing specification. On the basis of the quality standard of vinegar-processed Knoxiae Radix in Shandong Province Chinese herbal medicine processing specification (2012), 29 batches of Knoxiae Radix samples were collected. Following vinegar processing, the parameters including characteristics, moisture, total ash, acid insoluble ash, alcohol soluble extract content, microscopic, and thin layer and content determination were systematically studied and analyzed and the relevant limits were formulated. The project was established on the basis of the current quality standard, in which the microscopic identification, and the lucidin content determination were added, and the extractum item were revised when compared with current quality standard. This study established the Knoxiae Radix quality control index after vinegar processing. The established method of quality control is simple, reproducible, and accurate which can be used for quality control of vinegar-processed Knoxiae Radix.

Key words: vinegar-processed Knoxiae Radix, identification, quality standard, lucidin, content determination
