FooDB NameBeechwood, creosote (fagus spp.)
DescriptionGuajol or Guaiacol, also known as 2-hydroxyanisole or 2-methoxyphenol, belongs to the class of organic compounds known as methoxyphenols. Methoxyphenols are compounds containing a methoxy group attached to the benzene ring of a phenol moiety. Guaiacol is a phenolic compound with a methoxy group and is the monomethyl ether of catechol. Guaiacol is a sweet, medicinal, and phenolic tasting compound. Guaiacol is found in the highest concentration within a few different foods, such as sesames, coffee, and white wines and in a lower concentration in peppermints. Guaiacol has also been detected, but not quantified in white mustards, peppers, red bell peppers, cherry tomato, turmerics. Guaiacol is readily oxidized by the heme iron of peroxidases including the peroxidase of cyclooxygenase (COX) enzymes. It therefore serves as a reducing co-substrate for COX reactions. Guaiacol is a phenolic natural product first isolated from Guaiac resin and the oxidation of lignin. It is a yellowish aromatic oil that is now commonly derived from guaiacum or wood creosote. It is used medicinally as an expectorant, antiseptic, and local anesthetic. Guaiacol is used in traditional dental pulp sedation and has the property of inducing cell proliferation; guaiacol is a potent scavenger of reactive oxygen radicals and its radical scavenging activity may be associated with its effect on cell proliferation (PMID: 16152729). Guaiacol is used in the preparation of synthetic vanillin. Guaiacol is also present in wood smoke, as a product of pyrolysis of lignin. Guaiacol has been found in the urine of patients with neuroblastoma and pheochromocytoma. (PMID 4344880, 16152729)
