Abstract

Lotus rhizobia catabolized quercetin in an arabinose-based medium via a novel form of C-ring cleavage, yielding phloroglucinol and protocatechuic acid. Conservation of the A and B rings of the flavone suggests that a chalcone could be formed as a transient intermediate.

摘要

在阿拉伯糖为基础的培养基中,莲根瘤菌通过一种新型的 C 环裂解方式代谢槲皮素,生成根皮酚和原儿茶酸。黄酮类化合物的 A 环和 B 环的保守性表明,查尔酮可能是一种短暂的中间体。
