A chemoattractant of Ralstonia solanacearum isolated from the activated charcoal-adsorbed fraction of tomato root exudates was identified as ethyl β-d-glucopyranoside by instrumental analyses and comparison with synthetic preparations. Ethyl β-D-glucopyranoside showed unambiguous activity at above 1 µmol/disc. Its stereoisomers and D-glucose were inactive.
通过仪器分析并与合成制剂进行比较，从番茄根分泌物的活性炭吸附部分分离出的一种青枯雷尔氏菌趋化剂被鉴定为β-D-吡喃葡萄糖苷乙酯。β-D-吡喃葡萄糖苷乙酯在浓度高于1微摩尔/圆片时表现出明确的活性。其立体异构体和D-葡萄糖没有活性。
