Acylated Triterpene Saponins from the Stem Bark of Acer nikoense (Aceraceae)

抄録

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.
