溶纤维真杆菌将黄酮C-糖苷homorientin和isovitexin分别裂解为它们的糖苷配基毛地黄黄酮和芹菜素。相应的异构体，Orientin和Vitexin，或其他多酚C-葡萄糖苷没有去糖基化。E.纤维素溶剂还将黄酮和异黄酮的几种O-偶联葡糖苷裂解成它们相应的糖苷配基。
Eubacterium cellulosolvens cleaved the flavone C-glucosides homoorientin and isovitexin to their aglycones luteolin and apigenin, respectively. The corresponding isomers, orientin and vitexin, or other polyphenolic C-glucosides were not deglycosylated. E. cellulosolvens also cleaved several O-coupled glucosides of flavones and isoflavones to their corresponding aglycones.
