    Evaluation of leaves of Goniothalamus wynaadensis Bedd. for inhibition of metabolic viability of cancer cells & antimicrobial efficacy
    (Elsevier GmbH, 2019) Sharma A.; Sharma P.; Singh S.; Karegoudar T.B.; Holla H.
    Introduction: Goniothalamus wynaadensis Bedd. is a less explored medicinal plant belonging to the family Annonaceae. This species has been traditionally used by tribes of Wayanad, Kerala, in India, and also Indonesian tribes for joint-related ailments and also as a deodorizer. The aim of the study was to analyze leaf extracts of the plant for their antimicrobial and anticancer properties along with phytochemical screening. Methods: MTT assay was used to assess the cytotoxic potential of plant extracts against MDA-MB-231 and A-549. Antimicrobial potential of plant extracts was analyzed via liquid broth turbidometry assay and well in agar plate methods. Identification tests were carried out for phytochemical screening. Results: Antimicrobial assay showed EC50 values for ethyl acetate extract 0.82 mg/mL against Escherichia coli, 0.82 mg/mL against Salmonella typhi, & 0.88 mg/mL against Staphylococcus aureus which are quite significant. Other solvent extracts also displayed antimicrobial activities at varying dosage. MTT assay was performed at the dose concentrations of 1 ?g/mL, 5 ?g/mL & 25 ?g/mL, 50 ?g/mL and 100 ?g/mL to confirm the cytotoxicity of the extracts. The ethyl acetate extract displayed EC50 values of 4.96 ?g/mL against A-549 lung cancer cell line and 2.50 ?g/mL against MDA-MB-231 breast cancer cell line. Other extracts were also found to be cytotoxic. Conclusion: Ethyl acetate & water extracts have demonstrated potent activity against Salmonella typhi, Escherichia coli, & Staphylococcus aureus bacteria as well as, showing cytotoxicity against tested cancer cell lines. These results can be explored to identify individual phyto-molecules from the extracts with anticancer & antimicrobial potential.
