The 13C-DEPT spectra
(Table 3) revealed 30 carbon resonances, corresponding to seven
methyls, seven methylenes, nine methines (including two
oxygenated at dC 75.4 and 67.0, and three olefinic methines at
dC 133.5, 131.3 and 129.1) and seven quaternary carbons (including
an olefinic carbon at dC 134.0).
