An ent-kaurane diterpenoid from croton tonkinensis gagnep

A new ent-kaurane diterpenoid, ent-7β-hydroxy-15-oxokaur-16-en-18-yl acetate (1), has been isolated from the leaves of Croton tonkinensis Gagnep. (Euphorbiaceae). Its structure was established mainly by 1H and 13C nuclear magnetic resonance (n.m.r.) spectroscopy.
