Chemical Information
FooDB Name5-Isopropyl-2-methylphenol
DescriptionCarvacrol or 5-isopropyl-2-methylphenol is a naturally occurring organic compound classified as an alkylphenol (containing at least one aromatic ring) although biochemically, it is a monoterpenoid synthesized from isoprene units. Carvacrol is an isoprenoid lipid molecule that is very hydrophobic, practically insoluble in water, and relatively neutral. Carvacrol has a camphor, spice, and thymol taste with a characteristic pungent, warm odor of oregano. Carvacrol is found in highest concentrations in pot marjorams, common thymes, and black walnuts and in lower concentrations in rosemaries, common oregano, and sweet marjorams. Carvacrol was detected in pepper (spice), tamarinds, peppermints, lovages, and sweet basils making carvacrol a potential biomarker for the consumption of these foods. It has been added as a flavoring agent, preservative and fragrance in products. Its bioactivity and toxicological properties have been reviewed (PMID: 24915411). As a constituent of many essential oils, carvocrol was demonstrated to have anti-biofilm and anti-microbial properties (PMID: 30067078) and acts as an anti-viral against the norovirus (PMID: 24779581).
