Study effects the biological activity of Citrus sinensis against some pathogens

Abstract

The current study aimed to investigate the biological activity of the orang plant extract against some pathogens. The results of the inhibitory activity of the aqueous extract showed orange plant that the concentration of 100% gave the highest inhibitory activity against Klebsiella pneumoniae and Streptococcus pyogenes. The value of the inhibition diameter was 9 mm (P<0.05) and at the same concentration the diameter of inhibition was 18 mm for Enterococcus faecalis and 19 mm for Staphylococcus saprophyticus (P<0.01). The results of the aqueous extract of orange plant showed that the concentration of 100% gave the highest inhibitory activity against Candida albicans and Candida glabrata yeasts. The value of inhibition diameter was 22 and 18 mm, respectively (P<0.01).The results of the alcoholic extract of the orange plant showed that the 100% concentration gave the highest inhibitory activity against Enterococcus faecalis, the value of inhibition was 20 mm and the least significant difference was 6.35 , and the inhibition diameters were 17 mm for the alcoholic extract against Staphylococcus saprophyticus and Streptococcus pyogenes (P<0.01).Also, the results of the alcoholic extract of the orange plant showed that the concentration of 100% gave the highest inhibitory activity against Candida albicans and Candida glabrata yeasts. The value of inhibition diameter was 23 and 20 mm, respectively(P<0.01).
