Isocupressic acid is a diterpene acid present in a variety of conifer needles. It induces abortion in cattle.[1] It is found in all parts of the ponderosa pine (Pinus ponderosa), especially the needles. This gives its toxic and abortifacient effects.[2] It is also present in the lodgepole pine (P. contorta), the jeffrey pine (P. jeffreyi) and possibly in the monterey pine (P. radiata).[3]
