Three new acylated triterpene saponins, acernikoenosides A–C (1–3), were isolated from the stem bark of Acer nikoense, together with a known sterol glucoside. Their structures were elucidated on the basis of extensive spectroscopic analyses. This study provided the first example of triterpene saponins isolated from this plant. The anti-genotoxic activity of 1, 3 and 4 against ultraviolet irradiation was evaluated by comet assay.
