Abstract

This is box title

The total polyphenols and flavonoids contents of C. cardunculus, A. millefolium, C. officinalis, and M. chamomilla flowers, C. officinalis flowers have the highest of total polyphenols and flavonoids contents, which were 86.11 mg GAE/g and 11.59 mg GAE/g, respectively. Methanolic and aqueous extracts of plant flowers was antioxidant activity by used (FRAP, ABTS and DPPH) The methanolic and aqueous extracts of C. officinalis flowers have the highest reducing power which was ranged from 0.5054 to 1.8019 and 0.4215 to 1.3153 at the concentrations of 10 and 80 mg/ml, respectively. Also, by used (ABTS) it could be percentage were 90.17and 79.31%, While, by used (DPPH) it could be percentage of inhibition (IC50) which were 0.004 and 0.006 for methanolic and aqueous extracts respectively.
Keywords: polyphenols, flavonoids, plant extracts, antioxidant activity (FRAP-ABTS-DPPH).
