“…The HREIMS of 1 gave an intense parent ion at m / z 522.3324, corresponding to a molecular formula of C 33 H 46 O 5 , which required 11 degrees of unsaturation. Similar to morinins D and F, the 1 H NMR spectral data of 1 showed a cinnamyl alcohol, a methoxyl group at δ H 3.82 (3H, s), and an oxygenated angeloyl group at δ H 6.44 (1H, br q, J = 7.2 Hz, H-3‘), 2.12 (3H, d, J = 7.2 Hz, H-4‘), and 4.77 (2H, br s, H-5‘). Similarly to morinins D and F, in compound 1 the C-5‘ position of the angeloyl group was esterified, but in this case the moiety seemed to be an unsaturated fatty ester group, after careful analysis of the other signals of 1 H NMR spectrum.…”
