Abstract
Chemical and spectral studies of the major diterpene acid component of the bark of Croton oblongifolius, C20H30O2 and its conversion products (derivatives) have shown that it belongs to the pimarane group with the carboxyl in the 4-position (axial) and with the double bonds at Δ 7 and 15-positions and its stereochemistry is opposite that of isopimaric acid. It is therefore formulated as (+) isopimara-7 (8), 15-diene-19-oic acid.
