Two new skeletal triterpene lactones, spiromarienonols A ( 1a ) and B ( 2a ), were isolated from the stem bark of Abies mariesii Masters (Pinaceae). Based on spectral data and biogenetic considerations, their unique three‐dimensional structures were determined to be (3 R ,7 S ,9 R ,23 R )‐ ( 1a ) and (3 R ,7 S ,9 S ,23 R )‐3,7‐dihydroxy‐8‐oxo‐7(8→9) abeo ‐lanost‐24‐eno‐26,23‐lactone ( 2a ). Moreover, the potent activity of abiesenonic acid methyl ester ( 3 ) and abieslactone ( 4 ) against a disease‐oriented panel of 39 human cancer cell lines were investigated.
