Abstract/OtherAbstract:
|
The antioxidant and antimicrobial activities as well as the quantity of phenolic substances of Impatiens balsamina L. stem extracts obtained with various solvent were determined in this study. All of the extracts possessed moderate antioxidant potential in the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging and reducing power assays. Antimicrobial activity was estimated using the cylinder-plate and agar dilution methods against four bacterial and six fungal strains. The extracts showed good antimicrobial activity especially antifungal activity against all of the tested microorganisms. The total phenolic and flavonoid contents ranged from 2.88 to 13.63 mg gallic acid equivalents/g dried extract and 0.98 to 7.87 mg quercetin equivalents/g dried extract, respectively. The results presented here indicate that the I. balsamina stem extracts have antioxidant and antimicrobial properties and are therefore a potential source of antioxidant and antimicrobial agents for the food and pharmaceutical industries. Practical Application: Our work indicates that the I. balsamina stem may be a good candidate as natural antioxidant and antimicrobial agents. It can be applied in food industry for preservation. |
