Identification of Polyphenols Extracted from Pomelo Peel by Green Eutectic Solvent
In industrial production,traditional organic solvents are generally used to extract polyphenols from pomelo peel.In this paper,Meizhou pomelo peel and green solvent ionic liquid-eutectic solution were used as test materials and extraction solvents,and the polyphenols were identified and analyzed by high performance liquid chromatography(HPLC)and mass spectrometry(MS).A total of 819 substances of polyphenol extract from grapefruit peel were detected,including 43 kinds of flavonoids,108 kinds of flavonoids,78 kinds of phenolic substances,and then 11 kinds of polyphenol compounds were quantified.From small to large,the contents were gallic acid,hesperidin,quercetin,isoquercetin,catechin,epicatechin,sinensetin,isosinensetin,isorhamnetin,kaempferol and methylhesperidin.The contents of methylhesperidin and isorhamnose were the highest,isosweet orange flavone and sweet orange flavone were the second,and the contents of tangerine,catechin,epicatechin,kaempferol and isoquercetin were lower.
