Chemical composition, antioxidant and antibacterial activity of Adiantum capillus-veneris L. extract from Algeria

The present study evaluates the antioxidant and antibacterial activities as well chemical composition of aerial part Adiantum capillus-veneris L., which are endemic to flora Algeria. total phenolic amount hydromethanolic extract, measured by Folin-Ciocalteu reagent procedure, was found be about 23.44 ± 0.14 mg GAE/g DW, while flavonoid content value 4.66 0.01 CE/g aluminum chloride colorimetric method. power extract analyzed using DPPH radicals were scavenged with an IC50 65.85 µg/mL. activity against five bacterial strains Escherichia coli (ATCC 25922), Pseudomonas aeruginosa 25853), Staphylococcus aureus 25923), Streptococcus pneumoniae Bacillus cereus 10876) carried out disc diffusion test microdilution is most sensitive bacterium inhibition zone 9.0 1.1 cm MIC=10 mg/mL. Based on HPLC analysis, we find that quercetin 3-O-glucoside abundant compound in plant extract. This demonstrates could a potential natural source compounds.
