Two Prenylated Flavones from the Tree Bark of Artocarpus lanceifolius

, 2006
Two new prenylated flavones, artoindonesianins Z-1 (1) and Z-2 (2), together with two other known prenylated flavones, artobiloxantone (3) and cycloartobiloxanthone (4), had been isolated and identified from the chloroform extract of the tree bark of ...

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.
