Abstract

A new kaurane diterpene dimer, 15-oxozoapatlin-13alfa-yl-10'alfa,16'alfa-dihydroxy-9'alfa-methyl-20'-nor-kauran-19'-oic acid gamma-lactone-17'-oate (1), together with the known 13-hydroxy-15-oxozoapatlin (2), 10alfa,13alfa,16alfa,17-tetrahydroxy-9alfa-methyl-15-oxo-20-nor-kauran-19-oic acid gamma-lactone (3), 2alfa,10alfa,13alfa,16alfa,17-pentahydroxy-9alfa-methyl-15-oxo-20-nor-kauran-19-oic acid (19,10)-lactone (4), 3alfa,10alfa,13alfa,16alfa,17-pentahydroxy-9alfa-methyl-15-oxo-20-nor-kauran-19-oic acid gamma-lactone (5), and 1beta,16alfa,17-trihydroxy-ent-kaurane (6) were isolated from the leaves of Parinari campestris and identified on the basis of detailed spectral anal., including 2D NMR spectrometry and ESI-MS.
