Abstract:

Antibacterial activities of 200 kinds of plant extracts against Phytophthora sojae were tested by means of Paper Disk method. As a result,the extracts of Albizia lucidiorUncaria sessilifructus,and Albizia procera exhibited moderate inhibitory actions at the concentration of 10 μg/μL,while only the latter showed antibacterial activity at 2.5 μg/μL. Moreover,3-O-[α-L-arabinopyranosyl-(1→2)-β-D-fucopyranosyl-(1→6)-2-acetamido-2-deoxy-β-D-glucopyranosyl] echinocystic acid,the main active ingredient was isolated from Albizia procera.
