Two new Aromatic Glycosides from a Soil Bacterium Burkholderia gladioli OR1.

ABSTRACT

Two new aromatic glycosides, named as gladioside I (1) and II (2) were isolated from the culture broth of a soil bacterium, Burkholderia gladioli OR1. Both 1 and 2 contained one unit each of rhamnose and 3-O-methyl xylose and differed from each other in the aglycone part. Compound 1 contained an aromatic aldehyde and compound 2 contained a styrylcarbamate unit as the aglycone part. The structures of 1 and 2 were elucidated by detailed spectral analysis and chemical degradation.
