  Synthesis and antioxygenic activities of seabuckthorn flavone-3-ols and analogs

  摘要：

  A practical synthesis of polyhydroxy- and regiospecifically methylated flavone-3-ols which are components of commercial 'seabuckthorn flavone' has been achieved by modified Algar-Flynn-Oyamada method. Antioxidant activities of seabuckthorn extracts, isolated products and a number of flavone-3-ols have been determined. Structure-activity relationships have been discussed. Amongst the compounds tested, gallic acid, which is also present in seabuckthorn, was found to be the most effective antioxidant and radioprotectant. (C) 2011 Elsevier Ltd. All rights reserved.

  Potential sweetening agents of plant origin. 13. An intensely sweet dihydroflavonol derivative based on a natural product lead compound

  摘要：

  The dihydroflavonol dihydroquercetin 3-acetate (1) was isolated as a sweet constituent of the young shoots of Tessaria dodoneifolia (Hook. & Arn.) Cabrera (Compositae). Compound 1 and dihydroquercetin 3-acetate 4'-(methyl ether) (2), a novel synthetic analogue of this natural product lead compound, were rated by a taste panel as being 80 and 400 times sweeter than a 2% w/v sucrose solution, respectively. Synthetic dihydroquercetin 4'-(methyl ether) (3) showed a reduced sweetness intensity when compared to 2, while (+)-dihydroquercetin (4) was devoid of sweetness. Dihydroflavonol derivatives 1-3 represent a new class of potentially noncaloric and noncariogenic intense sweeteners.
