[Chemical constituents from Ilex hainanensis].Zhong Yao Cai. 2012 Aug; 35(8):1251-4.ZY
To investigate the chemical constituents from Ilex hainanensis.
The compounds were isolated and purified by various chromatographic techniques. The structures were identified by mass and NMR spectral data.
Ten compounds were isolated and identified as Ilexgenin A (1), 3beta, 19alpha-dihydroxyolean-12-ene-24,28-Dioicacid-28-O-beta-D-glucopyranoside (2), Ilexsaponin A1 (3), 2-(Caffeoyloxy) methyl-3-hydroxy-1-butane-4-O-beta-D-glucopyranoside (4), Dibutyl phthalate (5), Rutin (6), Eriodictyol-7-O-beta-D-glucopyranoside (7), Syringaresinol-4-O-beta-D-glucopyranoside (8), (2E) -2-methyl-2-butene-1, 4-diol-4-O-beta-D-(6"-O- caffeoyl) -glucopyranoside (9), 1-O-caffeoyl-(2E) -2-methyl-2-butene-1, 4-diol-4-O-beta-D- glucopyranoside (10), respectively.
Compound 4, 7 - 10 are obtained from this plant for the first time.
