Two new diarylheptanoid glycosides, named aceroside XII (7), C30H42O12, [α]D 70.3°, and aceroside XIII (8), C25H34O8, [α]D -40.2°, were isolated along with triterpenoids and caffeoyl esters from the branches of Acer triflorum KOM. (Aceraceae). On acid hydrolysis, 7 yielded (-)-centrolobol (9), glucose and apiose. On partial hydrolysis, 7 gave 8 and apiose. Acerosides XII (7) and XIII (8) were determined to be the 4''-O-β-D-apiofuranosyl-(1→6)-β-D-glucopyranoside and the 4''-O-β-D-glucopyranoside of (-)-centrolobol, respectively, on the basis of chemical and spectral evidence.
从三叶金合欢(Acer triflorum KOM.,槭树科)的枝条中分离出两种新的二芳基庚酮苷,分别命名为 Aceroside XII (7),C30H42O12,[α]D 70.3°和 Aceroside XIII (8),C25H34O8,[α]D -40.2°,以及三萜类化合物和咖啡酰酯。酸水解时,7 生成 (-)-centrolobol (9)、葡萄糖和芹糖。部分水解时,7 得到 8 和芹糖。根据化学和光谱证据,确定 Acerosides XII (7) 和 XIII (8) 分别是 (-)-centrolobol 的 4''-O-β-D-apiofuranosyl-(1→6)-β-D-glucopyranoside 和 4''-O-β-D-glucopyranoside。
