Abstract

The invention discloses an HPLC fingerprint spectrum detection method of the Sanle pulp oral liquid. The fingerprint of the invention has many peaks, good separation, good repeatability and high precision, which provides an effective guarantee for comprehensively monitoring the quality of the Sanle pulp oral liquid. Utilizing the extraction method and chromatographic conditions of the fingerprint detection method of the present invention, the contents of five active ingredients gallic acid, gallocatechin, epicatechin, corilagin and ellagic acid in the Sanle pulp oral liquid can also be measured , Realized the dual research on the qualitative and quantitative aspects of Sanle Porridge Oral Liquid.

Description

technical field [0001] The invention relates to an HPLC fingerprint detection method for Sanle pulp oral liquid, and belongs to the technical field of drug quality control methods. Background technique [0002] The prescription of Sanle Porridge is derived from Sanguo Decoction (also known as Zhebu Song Decoction), a famous Tibetan medicine prescription. In Tibetan medicine, they are respectively called Mole, Helile and Pilile, also known as Sanlejiang. In traditional Tibetan medicine, Sanguo Decoction has a significant effect on plague and plateau polycythemia [1] , is regarded as a tonic and strong drug; in modern medicine, it is found that it has a good immune regulation function, and it is effective for hyperlipidemia [2] , tumor [3] etc. have a certain therapeutic effect. In the 1990s, using emblica and myrobalan as raw materials, adding L-arginine, L-aspartic acid, honey and other auxiliary materials, developed Sanle pulp oral administration with functions of anti-...
