N2  - Another two diterpenes based on the (-)-kaurane skeleton have been isolated from Ricinocarpus stylosus. One is the known 16,17-dihydroxy-16&#946;-(-)-kauran-19-oic acid (IIb) and the other has been shown to be l&#945;,l9-dihydroxy-16&#945;-(-)-kauran-17-oic acid (IVa). The N.M.R. spectra of various kaurane derivatives in chloroform and benzene solutions are compared.
