Abstract:

 


Antioxidant
and antimicrobial activities of ethanol extracts of leaves, seeds and roots of
48 fruits and vegetables belonging to different families were investigated.
Also, the phytochemical constituents were established in samples. Antimicrobial
activity tests were carried out using agar disc diffusion methods with ten
microbial species and only two fungi strains. The extracts showed high
antibacterial activity against all the strains tested. It was observed that the
plant extracts were more active against Gram-negative bacteria than against
Gram-positive bacteria. The antioxidant properties of extracts were appraised
by means of different antioxidant tests, including total phenolic content,
2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging and metal
chelating activities. Phytochemical analysis revealed the presence of
carbohydrates, saponins, flavonoids, glycosides, tannins, phenols and alkaloids
in the extracts. When the protein content in samples was analyzed, the largest
values were obtained at 36.80% and 34.89% for Brassica oleracea acephala (Black Cabbage) and Corylus avellana (Hazelnut), respectively.
