摘要
从上新世华山松(PliocenePinusarmandii)化石木中分离鉴定了5个甾体成分:24ξ-n-丙基-胆甾烷-3-酮(1),豆甾烷-3-酮(2),24α-乙基-3α-胆甾醇(3),4-豆甾烯-3-酮(4)和3β-谷甾醇(5).化合物1为一个新的C30甾体.它们的结构由波谱方法鉴定.
A new C3o-steroid, named 24ζ-n-propyl-cholestan-3-one, together with four known steroids,stigmastan-3-one, 24α-ethyl-cholestan-3α-ol, stigmastan-4-en-3-one and 3βl-sitosterol was isolated from the pliocene lignified wood of Pinus armandii. Their structures were elucidated on the base of spectroscopic evidence.
