Graphical Abstract

Abstract

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.
