A new isopimarane diterpenoid from Vellozia pusilla pohl (velloziaceae)
Abstract
A new isopimarane diterpenoid, 8(9),15-isopimaradien-7-one-20,12-carbolactone (1), was isolated from Vellozia pusilla Pohl. Its structure was established on the basis of UV, IR, MS, uni and bidimensional ¹H and 13C NMR and comparison of the data with model compounds.
