Eight terpenoids(1-8) were isolated from the ethyl acetate soluble fraction of 80% ethanol extract of leaf of Toona sinensis through various column chromatographies on silica gel, Sephadex LH-20, MCI and ODS. Their structures were elucidated as 8β-hydroxypimar-15-en-19-oic acid methyl ester(1), cedrodorol B(2), 11β-acetoxyobacunol(3), toonayunnanin D(4), toonaciliatone D(5), toonaciliatone A(6), cedrelone(7), and 11β-hydroxygedunin(8) based on their chemical and physicochemical methods and spectroscopic data. Compound 1 was a new pimaradienediterpenoid and terpenoid 2-7 were isolated and identified from this plant for the first time.
