【 摘 要 】
A phenolic fractionwas obtained from of the acetone-water-acetic acid extract of Inga edulisleaves, by liquid-liquid partition and SPE-C18 cartridges. This methodprovided an increase of 108, 66, 51, 50 and 36% of flavonols, proanthocyanidins,total polyphenols, gallotannins and flavanols, respectively. The major phenolicsin purified fraction were procyanidin B2, catechin and myricetin-3-O-α-L-rhamnopyranoside,which achieved increases of 111, 47 and 45%, respectively, after SPE. Acid hydrolysisconfirmed the presence of procyanidins, prodelphinidins and glycosylated flavonoids.
