Abstract:

The use of synthesis antioxidant molecules is being dangerous anyway, because of the potential toxicological risks. In fact, new source of natural antioxidant molecules are required. The phenolics, natural compounds largely present in the vegetable kingdom, are recognized for their antioxidant activity and still little exploited by different industry. Our work aim is to evaluate the antioxidant capacity of the phenolic compounds extracted from the Algerian medicinal plant: Limoniastrum feei. This plant presented high levels of polyphenols ranged from 232.69 to 254.90 mg gallic acid equivalents/g dried extract, and flavonoids ranged from 106.33 to 129.66 mg catechin equivalents/g dried extract. The antioxidant activity of the methanolic crude extracts were evaluated using different antioxidant assays, including: reducing power and DPPH free radical scavenging activity. The results showed that the methanolic extract of Limoniastrum feei presented an average reducing power and more potent inhibition of DPPH radical activity. The study of organic fractions of this plant may reveal interesting results.
