Abstract
A novel acylated sterol glucoside (1) along with four known compounds, β-amyrin acetate (2), 3β,24-dihydroxytaraxer-14-ene (3), cleomiscosin A (4), and deomiscosin C (5), were isolated from the leaf and twig ofAcer okamotoanum Nakai (Aceraceae). The structure of the new compound was determined to be β-sitosterol glucoside-3’-0-hexacosanoicate based on chemical and spectroscopic analyses. In addition, the novel compound was found to exhibit a significant inhibitory effect (IC50 value of 0.2 (μM) on the complement system activated by the classical pathway.
