The purpose of the present work aimed at exploring the potential biochemical components and biological activities of an organic extract of the white truffle Tirmania nivea collected from the Iraqi desert, then test the organic extract against the Cytotoxicity on Human Larynx carcinoma cells and selected strains of pathogenic bacteria. Fourier transform infrared spectroscopy (FTIR) and gas chromatography-mass spectrometry GC/MSS were used to analyze mycochemical compositions. The antibacterial activity and Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) was investigated using a disk diffusion agar method. The truffle extract's cytotoxicity effect against the larynx cell line (Hep-2) was assessed by the MTT assay (in vitro). FTIR results provided the presence of phenol, carboxylic acid, and alkane's functional group, The GC-MS analysis of T. nivea disclose the existence of nineteen compounds that can contribute to the pharmaceutical properties of the truffle. As for antibacterial activity result, A growth inhibition activity of truffle extract at (18-40 mm inhibition zones) against the tested pathogenic bacterial strains was detected, which minimum inhibitory concentration values ranged from 3.12 to 6.25 mg/mL for Escherichia coli (ATCC 25922) and Staphylococcus aureus (ATCC 25923) Respectively. The results of cytotoxicity shown that the organic truffle extract exhibited a high inhibitory rate (52.685%) against cell line (Hep-2) at a concentration of 1.56 ?g/mL. In this work, the results showed that the organic extracts of T. nivea are very promising as cancer cytotoxicity and antibacterial agent for future medical applications.
