“…The 13 C NMR data of 10 are similar to those of 9, except for the signals attributed to the alkenylic carbon atoms, which were only recorded two signals at δ C 140.8 and 121.7. These 13 C NMR data are in agreement with the corresponding data described for sitosterol (Costa et al, 2008). , 3058, 2946, 2918, 2852, 1638, 1464, 1387, 1378, 1189, 1096, 1036, 992, 822 , 3078, 3058, 2946, 2918, 2852, 1646, 1464, 1387, 1378, 1189, 1096, 1036, 992, 880, 822; 1 H NMR (400 MHz, CDCl 3 ) δ H 4.67 (s, H-29a), 4.56 (s, H-29b); 13 , 2848, 1736, 1473, 1461, 1376, 1217, 736, 718; 1 H NMR (400 MHz, CDCl 3 ) δ H 5.46 (m, H-7), 4.57 (dd, J = 10.9 and 4.5 Hz, H-3), 2.10 (s, CO 2 Me); 13 …”
