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.
