Abstract

Three new grayanane diterpenoids, 14β-O-(2S,3R-nilyl)rhodomollein XVIII (1), 14β-O-(2S,3R-nilyl)rhodomollein I (2) and 14β-O-(2S,3R-nilyl) rhodojaponin III (3) have been isolated from the barks of Craibiodendron henryi. Their structures were determined on the basis of chemical and spectral methods. Vasodilator effects of these compounds were assessed.
