Abstract
Decoction of single medicinal herb is a reference for the standardization of different dosage form of Chinese medicine and it provides a new direction for solving the problems existing in the quality of Chinese medicinal granules such no uniform dosage forms and no clear quality standard. There are few reports on the idea, method and preparation of single herb standard decoction. Our country is in urgent need of that information in order to improve the consistency and stability of traditional Chinese medicine products. Here, Lonicerae Japinicae Flos was selected as an example to elucidate the preparation and quality evaluation of Chinese single herbal medicine decoction. Twelve batches of representative Lonicerae Japinicae Flos were collected, UPLC fingerprints were established, and the chemical structures of main peaks were identified with UPLC-QTOF-MS and standard compounds. The main components in the decoction are organic acids and iridoids. The extract rate of the standard decoction was (34.2±2.9)% and the transfer rate is (78.6±8.4)% in the form of chlorogenic acid, within the range of 75%-125% of mean. This paper established a method for the quality evaluation of standard decoction of Lonicerae Japinicae Flos and provided reference for the quality control method of terminal products from decoction of Lonicerae Japinicae Flos.
