Two diarylheptanoid glycosides, acerosides V (1) and XI (2), were isolated from the stem bark of Acer nikoense MAXIM. (Aceraceae). On hydrolysis, 1 and 2 yielded new diarylheptanoids, acerogenin D (6) and acerogenin E (7), respectively. Acerogenin D (6) was chemically correlated with acerogenin C (5), and acerogenin E, with alnusone (8). On the basis of the chemical and spectroscopic evidence, the chemical structures of 1 and 2 were established as the 2-O-β-D-glucopyranoside of acerogenin D and 3-O-β-D-glucopyranoside of acerogenin E, respectively. Aceroside XI is the first example of the biphenyl type of diarylheptanoid isolated from this plant. A. nikoense thus contains three types of diarylheptanoid, linear, cyclic biphenyl and cyclic diphenyl ether types.
