A multifunctional true CCoAOMT enzyme participates in the biosynthesis of polymethoxylated flavones in citrus.

Plant Physiology, 2023
Polymethoxylated flavones (PMFs) have received extensive attention due to their abundant bioactivities. Citrus peels specifically accumulate abundant PMFs, and methylation modification is a key step in PMF biosynthesis; however, the function of reported ...

Flavones and flavone synthases

Phytochemistry, 2005
Within the secondary metabolite class of flavonoids which consist of more than 9000 known structures, flavones define one of the largest subgroups. Their natural distribution is demonstrated for almost all plant tissues. Various flavone aglyca and their O- or C-glycosides have been described in the literature.

Flavones and flavone glycosides from Halophila johnsonii

Phytochemistry, 2008
Halophila johnsonii Eiseman is a shallow-water marine angiosperm which contains UV-absorbing metabolites. Studies on methanol extracts of H. johnsonii by means of HPLC-UV, NMR, HPLC-MS resulted in isolation and identification of seven previously unknown flavone glycosides: 5,6,7,3',4',5'-hexahydroxyflavone-7-O-beta-glucopyranoside (1), 5,6,7,3',4',5 ...

Flavone-3′-sulfonamide

Acta Crystallographica Section C Crystal Structure Communications, 2000
In the title mol­ecule, C15H11NO4S, the phenyl and benzene rings are quite planar, with maximum deviations from planarity of 0.009 (2) and 0.004 (1) A, respectively. The γ-pyrone ring deviates from planarity and makes a dihedral angle of 8.3 (3)° with the 2-phenyl substituent. The sulfon­amide group is involved in N—H⋯O hydrogen bonding.
