  Chemical constituents from the roots of Ampelopsis delavayana and their antibacterial activities

  摘要：

  Two new aromatic glycosides, 2-methylphenyl O-beta-D-xylopyranosyl-(1 -> 6)-O-beta-D-glucopyranoside (1) and 2-methylphenyl O-alpha-arabinofuranosyl( 1 -> 6)-O-beta-glucopyranoside (2), together with eight known compounds were isolated from the roots of Ampelopsis delavayana. Their structures were elucidated on the basis of extensive spectroscopic analysis. Furthermore, the in vitro antibacterial activities of 1 and 2 were investigated using serial twofold dilution in three bacteria including Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus.[GRAPHICS].
