PHYTOCHEMICAL, ANTIOXIDANT, AND ANTIMICROBIAL ACTIVITY OF Psidiumguajava LEAVES AGAINST ORAL DENTAL PATHOGENS

Deepa Garg, Nikhil Mohanan

Abstract :

Chemical substances used for prevention of dental caries are known to have many side–effects. Thus, natural products should be explored for their anticaries action. This study screened the antimicrobial effect of alcoholic and aqueous extractsof Psidiumguajava leaves against oral dental pathogens Streptococcus mutans, Staphylococcus aureus and Lactobacillus acidophilus.The aqueous extract showed greatest bacterial inhibition against Streptococcus mutans and Staphylococcus aureus strains, but methanolic extract was found more effective in inhibiting Lactobacillus acidophilus. phytochemical and antioxidative capacity analysis was also performed on the aqueous and ethanolic extracts for the presence of phenols, alkaloids, saponins, terpenoids, flavonoids, tannins and reducing sugar. The alcoholic leaf extracts showed higher anti oxidative capacity and phytochemicals content like alkaloids and steroids which are active antimicrobial components in plants.This investigation provides preliminary information for using guava leaf extracts to control dental problems.
