View through CrossRef
Four new labdane diterpenoid compounds, labda-7,12(E), 14-triene (1), labda-7,12(E),14-triene-17-al (2), labda-7,12(E),14-triene-17-ol (3) and labda-7,12(E),14-triene-17-oic acid (4) were isolated from the stem bark of Croton oblongifolius Roxb., the structure of the new compounds were established by spectroscopic data (IR, MS spectra, 1D and 2D NMR techniques including DEPT,COSY, NOESY, HMBC and HMQC) and by chemical transformation.
