Phytonutrients and Antimicrobial Activities of Methanolic Extract from Hafr Al-Batin Truffles

Abstract

The desert truffle is a wild mushroom, also referred to as Kamah or Fagaa. Kamah is a rich source of polysaccharides that have medicinal, antitumoral, antibacterial, and immune-stimulant effects. Studies of hypogeous fungi, especially desert truffles, have recently entered traditional studies of epigeous higher Basidiomycetes. Based on the tasty desert truffle Kamah obtained from Hafr Al-Batin Governorate, Saudi Arabia, as a source of potential antimicrobial agents with both the aim of obtaining novel agents toward bacteria and Fungi of clinical significance. We specifically tested the antibacterial and antifungal efficacy of methanol extracts of Kamah against the Gram-negative bacterial pathogens reference strains E. coli ATCC® 8739, P. Aeruginosa ATCC®9027, S. aureus ATCC®6538, Enterococci NCTC®775 and opportunistic fungus C. albicans ATCC®1231.The extract had MIC (minimum inhibitory concentrations) varying from 100 g/ml to 500 g/ml against the pathogens examined. The LC-QTOF-MS (liquid chromatography coupled to quadrupole time of flight mass spectrometry) phytoconstituents assay chromatogram indicated that the methanol extracts of Kamah comprises 264 with retention periods varying from 1.04 to 18.86, which were categorized as unsaturated and saturated natural ingredients sch as aromatic compounds, carboxylic acids, oxygenated hydrocarbons, fatty acids, amino acids, and vitamins).The main compounds were discovered to be 21 with peak areas larger than 2X10-5 and retention periods varying from 2.3 to 9.13.The main known substances with the maximum peaks were adenosine (11.724), phenylalanine (7.711), phenprobamate (7.711), and 5-hydroxytryptophan (5.711). Such preliminary findings, we assume, are encouraging in terms of obtaining a beneficial antibiotic substitute to battle antibiotic-resistant pathogens especially eye infections.
