ABSTRACT
The present study was carried out to investigate the preliminary phytochemical screening, total phenolic, tannin and flavonoid contents, in vitro antibacterial and antioxidant activities of different solvent extracts of Monstera deliciosa stem. Phytochemical screening was carried out using standard protocols. The antibacterial activity was carried out by agar well diffusion method and the antioxidant activity was performed by DPPH (2, 2-diphenyl-1-picryl-hydrazyl) method. The phytochemical screening study of Monstera deliciosa stem extracts revealed the presence of important phytochemicals namely Tannins, Steroids, Flavonoids, Alkaloids and Saponins. Hexane extract exhibited antibacterial activity against both Gram positive and Gram negative microorganisms tested. Ethyl acetate extract exhibited larger zone of inhibition on Serratia marcescens than the standard
Streptomycin. Hexane, Chloroform, Ethyl acetate and Methanol extracts at 100μg/ml and 200μg/ml concentrations exhibited more free radical scavenging activity than the standard Ascorbic acid, whereas hexane and chloroform extracts at 300μg/ml concentrations showed more free radical scavenging than the standard Ascorbic acid. The results of this study are suggesting the medicinal importance of this plant due to the presence of various phytochemicals.
Keywords: Monstera deliciosa, Phytochemical screening, Antibacterial activity, Antioxidant activity.
