ABSTRACT
Dihydroflavonol, a flavanone and two highly oxygenated flavones were isolated from the aerial parts of Thymus algeriensis Boiss. Spectroscopic methods [IR, UV, MS and 1H-NMR] confirmed their structures as 5,7,3',4-tetrahydroxydihydroflavonol [taxifolin], 5,7,3',4-tetrahydroxyflavanone [eriodictyol], 5,6-dihydroxy-7,3',4- trimethoxyflavone and 5,6,7-dimethoxyflavone. The dihydroflavonol taxifolin was reported for the first time in the genus Thymus. The significance of the co-occurrence of two different 5, 6-dihyroxyflavones was described. The chemotaxonomic implication of the obtained results was discussed
