A new and more efficient procedure was developed to obtain 5 beta-hydroxyresiniferonol-6 alpha,7 alpha-epoxide- 9,13,14-ortho(2,4,6-decatrienoate) [Excoecaria factor O1] by alkaline transesterification of corresponding 20-ester(s) genuinely present in latex of Excoecaria oppositifolia. It was
Thirteen compounds were isolated from roots of Stellera chamaejasme L. (Thymelaeaceae). They are 3-sitosterol (2), simplexin (3), pimelea factor P2 (4), daucosterol (5), (+)-3-hydroxy-1,5-diphenyl-1-pentanone (6), 4-ethoxy-benzoic acid (7), 2,4,6-Trimethoxy-benzoic acid (8), (+)-afzelechin (9),
