Evaluation of phenolic content and biological activities of Bunium mauritanicum tuberss

Abstract

The present work is carried out to evaluate biological activities of tubers extracts of Bunium mauritanicum. The methanol extract yield had higher (7.81%) tha n that of the aqueous extract (6.79%). The quantitative analysis of total phenols and flavonoid revealed that the highest concentration was recorded for the methanoic fraction with 89,442 ± 5,951μg EAG mg and 4.031 ± 0.141 μg EQ mg of extract respectively. In addition, the aqueous extract of tubers represents the most important antioxidant activity with an IC 50 of 0.14 mg ml against 2,2 diphenyl 1 picryl hydrazyl (DPPH Wherea s, the two extracts of the tubers have low reducing capacities compared to standard with EC 50 equal to 0.048 mg/ ml for the methanolic extract, 0.018 mg ml for t he aqueous extract and 0.009 mg/ ml for ascorbic acid. The methano l ic and aqueous extracts of Bunium mauritanicum reacted positively at least on one of the bacterial strains studied.
