主　　题：Albizia julibrissin Leguminosae triterpenoid saponin Julibroside J(27) cytotoxic activity 

摘      要：A new cytotoxic saponin(1). Julibrosides J(27), was isolated from the stem barks of Alibizia. julibrissin by chromatography, and the structure was elucidated as 3-O-beta-D-xylopyranosyl-(1--2)-beta -D- fucopyranosyl - (1--6) -beta -D-glucopyranosyl - 21-O-[(6S)-2 -trans-2-hydroxymethyl-6-methyl-6-O- [4-O-((6S)-2-trans-2-hydroxylmethy 6- methyl - 6- hydroxy)-2,7-octadienoyl-beta-D-quinovopy- -ranosyl]-2.7-octadienoyl}- acacic acid- 28 -O-beta-D-glucopranosyl-(1--3)-[(alpha-L-arabinofuranosyl-(1--4)]-alpha-L-rhamnopyranosyl-(1--2)-beta-D-glucopyrnosyl ester based on spectral and chemical evidences.
