Investigation of the leaves and stems of <i>Premna szemaoensis</i> resulted in the isolation of twelve new abietane diterpenoids, szemaoenoids A-L (1-12), together with four known abietane diterpenoids (13-16). The structures involved two rearranged-abietane skeletons: 17(15 → 16)-<i>abeo</i>-abietane (7, 10-12, 14 and 15) and 17(15 → 16),18(4 → 3)-<i>diabeo</i>-abietane (1-6, 13 and 16). The structures of the new compounds were established mainly by analyzing NMR and HRESIMS data. The absolute ...[more]
