leaves of Gonocaryum calleryanum afforded four new secoiridoid glycosides acylated with 2,3-dihydroxy-2-methylbutanoic acid, three of which have a novel 10-membered dilactone-ring. From this plant, we also isolated a new flavonoid glycoside, apigenin 7-O-β-apiofuranosyl (1 → 6)-β- d -glucopyranoside, along with six known flavonoids and flavonoid glycosides, apigenin, apigenin-5,7-dimethyl ether, apigenin
摘要 Gonocaryum calleryanum 的叶子提供了 4 种新的 2,3-二羟基-2-甲基丁酸酰化的二环环烯醚苷,其中 3 种具有新的 10 元双内酯环。从这种植物中,我们还分离出了一种新的黄酮苷,芹菜素 7-O-β-apiofuranosyl (1 → 6)-β-d-吡喃葡萄糖苷,以及六种已知的黄酮和黄酮苷,芹菜素,芹菜素-5,7-二甲基醚、芹菜素三甲醚、芹菜素 7-O-葡萄糖苷、芹菜素 7-O-新橙皮苷和牡荆素。通过化学和光谱手段阐明了新糖苷的结构。
