Abstract
In this experiment, the main compounds of stilbene glucoside and anthraquinones from polygonum multiflorum extract were separated by HPLC gradient elution. SinoChrom ODS-BP C18 is selected as chromatographic column. The optimal experimental conditions under 254nm wavelength UV detector include the column temperature: 26°C, mobile phase: methanol/water, and flow rate: 1.0ml/mol. The gradient method can be optimized by changing the steepness and shape of gradient elution. Through optimizing gradient method, the separation efficiency is improved within a certain range of gradient elution strength. This article provides important reference for quality control and content determination of fleece-flower root.
