Abstract
Phytochemical studies of Ilex macropoda led to the isolation of three new hemiterpene glycosides, 4-β-D-glucopyranosyloxy-5-hydroxyprenyl caffeate (aohada-glycoside A), 5-caffeoyloxy-4-β-D-glucopyranosyloxyprenyl alcohol (aohada-glycoside B), 4-(6-O-caffeoyl-β-D-glucopyranosyloxy)-5-hydroxyprenyl caffeate (aohada-glycoside C), together with betulin, acetyl ursolic acid, ilexosides XVII and XVIII, and 3, 4, 5-trimethoxyphenol β-D-5-O-caffeoyl-apiofuranosyl-(1→6)-β-D-glucopyranoside from the bark. Rotundioic acid, ursolic acid, ilexosides II and XXX, ziyu-glycoside I and rutin were also isolated from fresh leaves, and 3, 5-dicaffeoylquinic acid and 3, 4-dicaffeoylquinic acid from the wood.
