From the stem bark of Acer nikoense Maxim. (Aceraceae), three glycosides were isolated, namely aceroside III (1), C30H40O12, mp 138-141 deg C, D -98.4 deg, aceroside VI (2), C25H32O8*1/2H2O, mp 124-125 deg C, D -69.3 deg, and apiosylepirhododendrin (3), amorphous film (C21H32O11), D -59.5 deg.On acid hydrolysis, 1 yielded acerogenin A (4), apiose, glucose, and a partially hydrolyzed product 2, while 3 afforded (+)-rhododendrol (11), apiose, and glucose.Inspection of the carbon-13 nuclear magnetic resonance (13C NMR) and the PRFT-NMR spectra of 1 and 3 disclosed that they are apiosyl-(1->6)-glucosides.The proton nuclear magnetic resonance (1H NMR) spectral data of their permethylates (6 and 12) and the analytical data of methanolysis products of 6 and 12 established the structures of 1, 2 and 3 as acerogenin A 11-O-β-D-apiofuranosyl-(1->6)-β-D-glucopyranoside, acerogenin A 11-O-β-D-glucopyranoside and (+)-rhododendrol 2-O-β-D-apiofuranosyl-(1->6)-β-D-glucanopyranoside, respectively.Keywords - Acer nikoense; Aceraceae; diarylheptanoid; arylbutanol; apiosylglucoside; aceroside (III, VI); apiosylepirhododendrin; (+)-rhododendrol; PRFT-NMR
