A new abietane diterpene, named abietopinoic acid, and a new podocarpane diterpene, named podopinoic acid, were isolated from the acetone extract of the heartwood of Pinus massoniana. Their structures were established as 12‐hydroxy‐7‐oxoabieta‐8,11,13‐trien‐18‐oic acid ( 1 ) and 13‐hydroxy‐7‐oxopodocarpane ( 2 ) by means of spectroscopic analyses including 2D‐NMR. To the best of our knowledge, this is the second report of a podocarpa‐8,11,13‐trien‐18‐oic acid diterpene, isolated from the genus Pinus.
