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.
通过对大戟科植物的植物化学研究,分离出了三种新的半萜苷,即 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),以及来自树皮的 betulin、acetyl ursolic acid、ilexosides XVII 和 XVIII 以及 3, 4, 5-trimethoxyphenol β-D-5-O-caffeoyl-apiofuranosyl-(1→6)-β-D-glucopyranoside 。此外,还从鲜叶中分离出 Rotundioic acid、熊果酸、ilexosides II 和 XXX、ziyu-glycoside I 和芦丁,从木材中分离出 3,5-二咖啡酰奎宁酸和 3,4-二咖啡酰奎宁酸。
