Ganoderma lucidum Methanolic Extraction as a Potent Phytoconstituent: Characterization, in-vitro Antimicrobial and Cytotoxic Activity

From the paper

Abstract

Background: Ganoderma lucidum has attracted tremendous attention due to its exceptional antimicrobial and anticancer properties that can be delicately tuned by controlling the initial extraction content and concentration. In the present experiment, we detailed the characterization, antimicrobial, and cytotoxic performance of Ganoderma lucidum as a potential multi-functional therapeutic agent. Methods: In this study, we used FTIR, XRD, FESEM, EDX, and HPLC techniques to evaluate the samples, which were then followed by disc diffusion and microdilution broth methods to test its antibacterial effects against four Gram-positive and Gram-negative bacterial strains, Enterococcus faecalis, Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa. MTT assay was applied to determine the cytotoxic activity of this natural product against MCF-7 and K562 cancer cell lines. Results: The results revealed that the inhibitory effects of this product had higher antibacterial activity against E. coli and Pseudomonas aeruginosa. The IC50 values of 0.5 and 0.75 mg/mL were obtained for MCF-7 and K-562 cancer cell lines, which confirmed the higher anticancer activity of the GLME against breast cancer cells compared to blood cancer cells. Conclusions: Hence, these data provide pioneer insights into the therapeutic usage of Ganoderma lucidum for treating breast and blood cancers. This work is motivated by research studies looking for pharmacological products to address chronic and acute diseases, where further resources and studies are required to explore such products' adverse effects and toxicity.
