A range of ST cDNAs has been identified from functional genomics studies of A. thaliana, including one (AtST3) that has been shown to encode a flavonoid 7-ST. Unlike BFST3, AtST3 recombinant protein accepts a number of flavonol and flavone aglycones, as well as their 3-O-monosulfated derivatives.However, strict specificity to the 7-hydroxyl was found. [Pg.171]

Table 5.38 b. Structures and 13C Chemical Shifts (<5C in ppm) of Selected Chalcones, Flavones, Flavonols, Isoflavones, Dihydro-flavones, Dihydroflavonols and Flavons (Aglycones). Spectra were Recorded in DMSO-d6, Except those of Flavone (CDC13) and 2 -Hydroxy-, and 2,2 -Dihydroxychalcone (D20/DMS0-d6 (2 7)) [989, 990]. [Pg.452]

The most frequently used solvent for flavones is hexadeuterodi-methylsulfoxide (DMSO- 56) and tetradeuteromethanol (CD3OD). For lypophilic flavone aglycones, solvents such as carbontetrachloride (CCI4) are recommended. [Pg.228]

Two-phase solvent systems composed of chloroform-methanol-water at various volume ratios are frequently used for the separation of moderately hydrophobic compounds, including flavone aglycones, phenylpropanoids, iridoid glycosides, and so forth [6]. [Pg.1382]
