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.
从土壤细菌唐菖蒲伯克霍尔德氏菌OR1的培养液中分离出两种新的芳香糖苷，命名为唐菖蒲苷I（1）和II（2）。化合物1和2均各含有一个鼠李糖单元和一个3 - O - 甲基木糖单元，苷元部分彼此不同。化合物1含有一个芳香醛，化合物2含有一个苯乙烯基氨基甲酸酯单元作为苷元部分。通过详细的光谱分析和化学降解确定了1和2的结构。
