| Abstract: | High performance liquid chromatography coupled with electrospray ionization mass spectrometry was used to study the phenolics profile of Persian walnut(Juglans regia L.) seeds.Four isomers of HHDP(Hexahydroxydiphenoyl)-glucopyranose,2 isomers of valoneoyl-glucopyranose,2 isomers of di-HHDP-glucopyranose,3 isomers of galloy-valoneoyl-glucopyranose and 2 isomers of digalloy-glucopyranose were found to be present in Persian walnut seeds with a number of,as yet,unknown compounds.The results illustrate that the ... |
