A new C30-steroid, named 24ξ-n-propyl-cholestan-3-one, together with four known steroids, stigmastan-3-one, 24α-ethyl-cholestan-3α-ol, stigmastan-4-en-3-one and 3β-sitosterol was isolated from the pliocene lignified wood of Pinus armandii. Their structures were elucidated on the base of spectroscopic evidence.

Key words: Pinus armandii, pliocene, C30-steroid, fossil wood
