a In the 1H NMR spectrum, the signal due to the olefinic proton resonating at 5.48 (t, J = 3.3 Hz, 1H) is characteristic of oleanolic acid; the signals due to the allylic protons resonating at 2.84 (dd, J = 14.6, 2.0 Hz, 1H) and 2.60 (d, J = 14.0 Hz, 1H) is characteristic of δ-oleanolic acid. In the 13C NMR spectrum, the signals due to the olefinic carbons resonating at 123.8 and 146.1 is characteristic of oleanolic acid (1); the signals due to the olefinic carbons resonating at 130.6 and 139.2 is characteristic of δ-oleanolic acid (2).
