Abstract:
Ten compounds were isolated from the 95% ethanol extract of the stem bark of Toona sinensis by silica gel, ODS Sephadex LH-20 column chromatographies and preparation TLC methods. Their structures were elucidated by spectroscopic methods and chemical properties as betulinic acid(1), stigmastane-3, 6-dione(2), stigmast-4-en-3-one(3), 7β-hydroxysitosterol(4), 6-hydroxystigmast-4-en-3-one(5), stigmast-4-ene-3β, 6β-diol(6), ergosterol peroxide(7), 7-methoxy-2-(3, 4-methylenedioxyphenyl)benzofuran-5-carboxylate(8), canthin-6-one(9), and α-acetylamino-phenylpropyl α-benzoylamino phenylpropionate(10). All compounds were isolated from T. sinensis for the first time.
