title: New abietane-type diterpenes from the heartwood of Picea morrisonicola.
abstract: New abietane-type diterpenes, 15-acetoxy-7-oxodehydroabietic acid (1), picealactones A (2), B (3), and C (4), together with the known 7-oxodehydroabietic acid (5) were isolated and identified from the heartwood of Picea morrisonicola. The structures of 1-4 were determined on the basis of spectral data explanation. Compounds 2-4 possessed a rare 5-dehydro-18, 6-olide functionality. Compounds 1 and 2 were first isolated from natural source.
