Composition Analysis of Phenolic Compounds with Different Polarities in Walnut Green Husk
摘要
Abstract
As a by﹣product of walnut processing, walnut green husk contains different polar phenolic substances with different compositions. In order to grading utilization of walnut green husk resources, orthogonal test was used to optimize the extraction process of phenols and prepare phenols crude extracts from walnut green husk. On this basis, water, petroleum ether, dichloromethane and ethyl acetate were used to extract phenolic compounds with different polarities, and the ethyl acetate layer and water layer were collected separately. HPLC was used to analyze the composition of the crude extract and high resolution mass spectrometry was used to analyze the composition of the ethyl acetate layer and water layer. The results showed that the ethyl acetate layer sample contained protocatechuic aldehyde, protocatechuic acid, syringic acid, ellagic acid, catechin or epicatechin, skin resin alcohol, quercetin derivative and triacyl glucose. While the water layer samples contained picorealol, gallic acid gluconate, and short﹣leaved hematoxylin carboxylic acid. In general, phenolic compounds with different polarities in walnut green husk have different compositions, and could be used in grades according to its composition characteristics and widely used in various fields of food or additives.关键词
