Abstract
The disclosure discloses a method for separating phenolic acid glucoside compounds from, belonging to the technical field of food. The method includes the following steps: (1) extraction: crushing, and then extracting by using ethanol to obtain walnut ethanol extract; and (2) separation: performing column chromatography on the walnut ethanol extract obtained in step (1), sequentially eluting by using ethanol of different concentrations, purifying and eluting repeatedly, and performing separation to obtain phenolic acid glucoside compounds. The phenolic acid glucoside compounds are 2-hydroxyl-5-methoxylphenyl-O-β-D-glucopyranoside, 6-hydroxylnaphthyl-1,2-di-O-β-D-glucopyranoside and 2,6-dihydroxynaphthyl-O-β-D-glucopyranoside. Pharmacological experiments confirm that the three compounds have good antioxidant activity.
