摘要: 石竹科植物多荚草(Polycarpon prostratum (Forssk.)Aschers. et Schwein. ex Aschers)的全草中分离得到了2个新的柴胡皂甙类化合物:prostratoside D和E.它们的结构通过波谱方法分别鉴定为3-O-{β-D-xylopyranosyl-(1→2)-β-D-glucopyranosyl-(1→4)-[β-D-glucopyranosyl-(1→2)]-a-L-arabinopyranoside}-saikogeninD和3-O-{β-D-xylopyranosyl-(1→2)-β-D-glucopyranosyl-(1→4)-[β-D-glucopyranosyl-(1→2)]-α-L-arabinopyranoside}-saikogeninG.

Abstract: Two new triterpenoid saponins, namely prostratoside D and E, were isolated from the whole plants of Polycarpon prostratum (Forssk.)Aschers. et Schwein. ex Aschers.By spectroscopic methods, their structures were determined as 3-O-{β-D-xylopyranosyl-(1→2)-β-D-glucopyranosyl-(1→4)-[β-D-glucopyranosyl-(1→2)]-a-L-arabinopyranoside}-saikogeninD和3-O-{β-D-xylopyranosyl-(1→2)-β-D-glucopyranosyl-(1→4)-[β-D-glucopyranosyl-(1→2)]-α-L-arabinopyranoside}-saikogenin G,respectively.
