[摘要]:Three new grayanane diterpenoids, 14b-O-(2S,3R-nilyl)rhodomollein XVIII (I), 14b-O-(2S,3R-nilyl)rhodomollein I (II) and 14b-O-(2S,3R-nilyl)rhodojaponin III (III) have been isolated from the barks of Craibiodendron henryi. Their structures were detd. on the basis of chem. and spectral methods. Vasodilator effects of these compds. were assessed.
