Phytochemical Screening, Antioxidant and Insecticidal Activities of Ajuga iva

Abstract

Ajuga iva. is a species of genus Ajuga family Lamiaceae. It is considered among the most used in traditional medicine in the Maghreb species. In this study, phytochemical screening of Ajuga iva showed the presence of chemical groups of secondary metabolites: tannins, alkaloids, saponosids and flavonoids. Extraction of flavonoids from the aerial parts of Ajuga iva. was carried out by maceration in an alcohol mixture (methanol / water) and confronted by various organic solvents (CE, EAE, BuOH-E, AE).The quantitative estimation of total phenolic and total flavonoids showed that the aqueous extract present the highest phenolic fraction(19.41 ± 0.718 mg EAG/ g extract) and highest flavonoids content of (4.14 ± 0.067 μgEQ / g extract). This study was also investigated for the antioxidant activity (FRAP and DPPH methods) of flavonoid extract from Ajuga iva.The insecticidal activity of flavonoid extract of Ajuga iva was evaluated against individuals Rhyzopertha dominica. Results showed a low activity of the crude extract with a maximum mortality of 31.66 ± 1.59%.
