Abstract

n-Alkanes C₁₃-C₃₄, isoalkanes C₁₅-C₁₉, waxes, docosanol, tetracosanol, (24R)-24-ethylcholest-4-en-3-one, (24R)-24-methylcholest-5-en-3β-ol, (24R)-24-ethylcholest-5-en-3β-ol (β-sitosterol), (13S)-labda-8(17),14- dien-13β-ol(13-epimanool), C(14a)-homo-27-norgammacer-14-ene-3β,21α- diol (serratenediol), C(14a)-homo-27-norgammacer-14-ene-3β,21β-diol (21-episerratenediol), 3β-hydroxy-C(14a)-homo-27-norgammacer-14-en-21- one, and 3β-methoxy-C(14a)-homo-27-norgammacer-14-en-21 one have been identified in the neutral fraction of the benzene extractives from the bark of Pinus radiata D. Don.
