Two new acylated flavone C-glycosides, 6-O-(2-methylbutyryl)isoswertisin (1) and 6-O-(2-methylbutyryl)isoswertiajaponin (2), together with four known acylated flavone C-glycosides, were isolated for the first time from the whole plants of Hemistepta lyrata (Compositae). Their structures ...
Tricetin Di-C-GlycosidesFrom Metzgeria furcata (L.) Dum. and M. furcata var. ulvula Nees. 12 different flavone Cglycosides were isolated and identified; 4 of them are common to both varieties. The detected compounds are three tricetin 6,8-di-C-glycosides, one of them 6-C-尾-D-...
Flavone C-glycosides are a type of flavonoid compounds that have been studied for their pharmacological significance, particularly in relation to their potential antidiabetic effects. These compounds are found in cereals and have been of interest in the field of crop improvement and biotechnological syn...
2.2 Flavonoid C-glycosides Flavonoid C-glycoside is linked by the anomeric carbon of sugar and flavonoid skeleton through a C-C bond. Natural C-glycosides have been detected on flavones, flavonols, isoflavones and chalcones. The most important sub-class is flavone C-glycoside. The C-glycosides ...
