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.

[Objectives]This study was conducted to investigate the effects of different heavy metal stresses on seed germination,in order to provide a theoretical basis for phytoremediation of soil heavy metal pollution.[Methods]With the seeds of *** as an experimental material,the germination test of *** seeds under different concentrations of Cu^(2+),Zn^(2+) and Pb^(2+) was carried *** germination potential,germination rate,germination index,radicle length,embryo length and other indexes were measured.[Results]①Different heavy metals had different effects on the germination of *** *** concentrations of Cu^(2+),Zn^(2+) and Pb^(2+) stresses had certain promotion effects on the germination of *** seeds,but high concentrations of Cu^(2+),Zn^(2+),Pb^(2+) stresses had obvious inhibitory effects on the germination of *** seeds.②There were obvious differences in the tolerance of *** seeds to different metal ion *** to the comparison of the average values of membership functions,the order of their tolerance to different heavy metal ions was:Zn^(2+)>Cu^(2+)>Pb^(2+).[Conclusions]In the case of light pollution,the germination of *** seeds was not inhibited,and the use of this plant for the remediation of lightly contaminated soil with heavy metals can also be considered.
