TL;DR: C-glycosylation, for the biogenesis of C -glycosylflavones, has been demonstrated to occur at the flavanone level for axenically-cultured Spirodela polyrhiza clone 7003 and the data suggests that the enzyme which oxidizes Flavanone (chalcone) to flavone is irreversible under the described experimental conditions.

TL;DR: The formation of flavanone metabolites was not suppressed by the administration of high doses of the antibacterial compounds aureomycin and phthaloylsulphathiazole and the application of combined gas-liquid chromatography/mass spectrometry and proton nuclear-magnetic-resonance spectroscopy to the and identification of the flavan one metabolites is described.
Abstract: 1. The metabolism of flavanone in the rat was studied after oral or intraperitoneal administration of the compound. Flavone and flav-3-ene together with five other unidentified minor metabolites were excreted in the urine. 2. The formation of flavanone metabolites was not suppressed by the administration of high doses of the antibacterial compounds aureomycin and phthaloylsulphathiazole. 3. No aromatic acids that could be attributed to ring cleavage of flavanone were detected. 4. Administration of 100 or 200mg of flavanone daily per rat caused some deaths during the 7–14-day period. 5. The application of combined gas–liquid chromatography/mass spectrometry and proton nuclear-magnetic-resonance spectroscopy to the separation and identification of the flavanone metabolites is described. 6. Measurement of the two major flavanone metabolites was carried out by gas–liquid chromatography.

TL;DR: Two new flavanones were isolated from Guang-Dou-Gen (the root of Sophora subprostrata CHUN et T.CHEN) and their structures were established from their spectral data and comparison with the corresponding synthesized derivatives as 4', 7-dihydroxy-6, 8-bis(3-methyl-2-butenyl)flavanone (I), and 2-[(7'-hydroxy-2', 2'-dimethyl-2H-benzopyran)-6'-yl]-7-hydrox-8-(

TL;DR: A number of sulfanilamides and tosylamides of 2′-hydroxychalcones, flavanone, flavonols and flavone was synthesized.
Abstract: Es wurden mehrere Sulfanilamid- und Tosylamidderivate von 2′-Hydroxy-chalkonen, Flavanon, Flavonolen und Flavon dargestellt und in zwei Fallen polymorphe Modifikationen isoliert. Die physikalisch-chemischen Eigenschaften der Verbindungen, die antimikrobiell unwirksam sind, werden mit denen der Bis(chromonyl-2)-benzole verglichen.
Sulfanilamide Derivatives of Flavonoids
A number of sulfanilamides and tosylamides of 2′-hydroxychalcones, flavanone, flavonols and flavone was synthesized. In two cases polymorphic modifications could be isolated. The physical and chemical properties of the compounds which are not active against microorganisms are compared with bis(chromonyl-2)-benzenes.
