- Abstract
The chemical constituent analysis on the whole plant Eremostachys loasifolia (Family: Lamiaceae) resulted 13 compounds of flavonoids class for the first time from this species namely Loasifolin (1), Eremoside A (2), Eremoside B (3), Kaempferol (3,4',5,7-tetrahydroxyflavone) (4), 5-Hydroxy-6,7,8,4'- tetramethoxyflavone (5), 5-Hydroxy-3',4',6,7,8-pentamethoxyflavone (6), Apigenin (4',5,7-trihydroxyflavone) (7), Luteolin (3',4',5,7-tetrahydroxyflavone) (8), Apigenin 7-O-β-D-glucopyranose (9) 4-Methyl Kaempferol (3,5,6-trihydroxy-4methoxy flavone) (10) 5-Hydroxy-7,4-dimethoxy flavones (11), 6,7-Dimethoxy-4,5- hydroxyflavone (12), 3,5,7-Trihydroxy-3',4'-dimethoxyflavone (13). Further, all isolated compounds showed antioxidant activity. The structures of isolated compounds were determined using different spectroscopic techniques including NMR, UV/Vis., IR and MS.
