Evaluation of the Antimicrobial, Antioxidant, and Cytotoxicity Against MCF-7 Breast Cancer Cell Lines of <i>Phyllanthus emblica</i> L. Bark Extract

Abstract

Background: The euphorbiaceous plant family includes Phyllanthus emblica, which demonstrates a variety of pharmacological qualities. Aim: This study aims to investigate any potential medical benefits that the Phyllanthus emblica tree’s bark may have. Methods: An aqueous extract was made with sterile water, and alcohol-based extracts were obtained by macerating with 100% ethanol. Different extraction parameters were changed to evaluate their impact on polyphenol extraction, such as the concentrations of ethanol and aqueous extracts. The phosphomolybdate method was used to assess antioxidant activity and Total Phenol Content (TPC). Both ethanolic and aqueous extracts were found to have antibacterial activity against clinical isolates of Pseudomonas aeruginosa, Staphylococcus aureus, and Escherichia coli. Thin Layer Chromatography (TLC) was used to compare the extracts’ metabolite profiles. The MTT assay was employed to detect cell growth and survival, and the ethanolic bark extract showed potential cytotoxic action against the MCF 7 cancer cell line. Result: The results of the aforementioned tests showed that the ethanolic bark extract had greater antibacterial activity than the aqueous extract. Furthermore, the MTT assay showed that the ethanolic bark extract may have cytotoxic effects on the cancer cell line MCF 7. Conclusion: In summary, more research is necessary to completely understand the antibacterial and chemotherapeutic effects of the active ingredients, opening the door for their possible development as effective anticancer treatments.
