- 9.6 Description
- Methyl salicylate (oil of wintergreen or wintergreen oil) is an organic ester that is naturally produced by many species of plants. Some of the plants which produce it are called wintergreens, hence the common name. This compound is used as a fragrance. It is also found in liniments (rubbing ointments).
- 9.7 Chemical Properties
- Methyl Salicylate is the main component of wintergreen oil and occurs in small quantities in other essential oils and fruits. It is a colorless liquid with a sweet, phenolic odor.
- 9.8 Chemical Properties
- Methyl salicylate has a characteristic wintergreen-like odor. May be prepared by extraction from natural sources; or by esterification of salicylic acid with methanol.
- 9.9 Chemical Properties
- Wintergreen is an evergreen shrub with slender, creeping stems, assurgent, flowering branches with toothed leaves clustered at the top, white, bell-shaped flowers blossoming July to August, followed by red berries (checkerberries). The plant grows extensively in the woods of Canada and the United States (Pennsylvania). The leaves are harvested between June and September. Wintergreen has an aromatic odor and flavor similar to methyl salicylate.
- 9.10 Occurrence
- Numerous plants produce methyl salicylate in very small amounts. Some plants, such as the following, produce more:
Some species of the genus Gaultheria in the family Ericaceae, including Gaultheria procumbens, the wintergreen or eastern teaberry;
Some species of the genus Betula in the family Betulaceae, particularly those in the subgenus Betulenta such as B. lenta, the black birch;
All species of the genus Spiraea in the family Rosaceae, also called the meadowsweets.
This compound is produced most likely as an anti-herbivore defense. If the plant is infected with herbivorous insects, the release of methyl salicylate may function as an aid in the recruitment of beneficial insects to kill the herbivorous insects.Aside from its toxicity, methyl salicylate may also be used by plants as a pheromone to warn other plants of pathogens such as tobacco mosaic virus.
- 9.11 Uses
- Methyl salicylate occurs in the leaves ofGaultheria procumbens L. and in the barkof Betulaceae. It is produced by esterificationof salicylic acid with methanol. It is used inperfumery and as a flavoring agent.
- 9.12 Uses
- In high concentrations as a rubefacient in deep heating liniments (such as Bengay) to treat joint and muscular pain. Randomised double blind trial reviews report evidence of its effectiveness that is weak, but stronger for acute pain than chronic pain, and that effectiveness may be due entirely to counter-irritation. However, in the body it metabolizes into salicylates, including salicylic acid, a known NSAID.
In low concentrations as a flavoring agent (no more than 0.04%; it is toxic).
providing fragrance to various products and as an odor-masking agent for some organophosphate pesticides. If used excessively, it can cause stomach and kidney problems.
Attracting male orchid bees, who apparently gather the chemical to synthesize pheromones; it is commonly used as bait to attract and collect these bees for study.
Clear plant or animal tissue samples of color, and as such is useful for microscopy and immunohistochemistry when excess pigments obscure structures or block light in the tissue being examined. This clearing generally only takes a few minutes, but the tissue must first be dehydrated in alcohol.
A mint flavoring in some kinds of chewing gum and candy, as an alternative to the more common peppermint and spearmint oils. It can also be found as a flavoring of root beer. It is also a potentially entertaining source of tri boluminescence ; when mixed with sugar and dried, it gains the tendency to build up electrical charge when crushed or rubbed. This effect can be observed by crushing wintergreen Life Savers candy in a dark room. - View all

- Colorless yellowish or reddish liquid with odor of wintergreen.
- 9.24 Air & Water Reactions
- Insoluble in water.
- 9.25 Reactivity Profile
- Methyl Salicylate is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. Birch-Me is incompatible with oxidizers. Birch-Me is also incompatible with strong bases. Birch-Me may react with iron salts.
- 9.26 Hazard
- Toxic by ingestion; use in foods restrictedby FDA, lethal dose 30 cc in adults, 10 cc in chil-dren.
- 9.27 Health Hazard
- Methyl salicylate is a highly toxic compound.The toxic symptoms in humans include nausea, vomiting, gastritis, diarrhea, respiratorystimulation, labored breathing, pulmonaryedema, convulsions, and coma. Ingestion of15 to 25 mL of this compound may befatal to humans. Application of the liquidon the skin and eyes produced severe irrita tion in rabbits. Oral, subcutaneous, or der mal administration of methyl salicylate intest animals produced specific developmen tal abnormalities affecting the eyes, ears, andcentral nervous system
Toxicity of this compound is relativelymore severe in humans than in many com mon laboratory animals. The oral LD50 values in test animals were within the range800–1300 mg/kg.
- 9.28 Fire Hazard
- Methyl salicylate is combustible.
- 9.29 Biochem/physiol Actions
- Methyl salicylate plays an important role in fruit ripening. It is known to attract natural enemies of herbivores. MeSA inhibits the activity of aminocyclopropane-1-carboxylic acid synthase (ACC synthase) and aminocyclopropane-1-carboxylic acid oxidase (ACC oxidase) in plums and tomatoes, it can inhibit fungal infections and reduce chilling injury symptoms in fruits like pomegranates. This oil of wintergreen is of great interest in the tobacco industry as a flavorant. It has counter irritant and anti-inflammatory effects.
- 9.30 Contact allergens
- This anti-inflammatory agent is found in a wide number of ointments and can induce allergic contact dermatitis.
- 9.31 Safety Profile
- Human poison by ingestion. Moderately toxic to humans by an unspecified route. Moderately toxic experimentally by intraperitoneal, intravenous, and subcutaneous routes. An experimental teratogen. Human systemic effects by ingestion: flaccid paralysis without anesthesia, general anesthesia, dyspnea, nausea, vomiting, and respiratory stimulation. Experimental reproductive effects. A severe skin and eye irritant. Ingestion of relatively small amounts has caused severe poisoning and death. Combustible liquid when exposed to heat or flame; can react with oxibzing materials. To fight fire, use CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes.
- 9.32 Safety
- In pure form, methyl salicylate is toxic, especially when taken internally. A single teaspoon (5ml) of methyl salicylate contains 7g of salicylate, which is equivalent to more than twenty- three 300 mg aspirin tablets. The lowest published lethal dose is 101 mg / kg body weight in adult humans , (or 7.07 grams for a 70 - kg adult). It has proven fatal to small children in doses as small as 4 ml.[6] A seventeen-year- old cross - country runner at Notre Dame Academy on Staten Island, died in April 2007, after her body absorbed methyl salicylate through excessive use of topical muscle-pain relief products.
Most instances of human toxicity due to methyl salicylate are a result of over-application of topical analgesics, especially involving children. Some people have intentionally ingested large amounts of oil of wintergreen. Salicylate, the major metabolite of methyl salicylate, may be quantitated in blood, plasma or serum to confirm a diagnosis of poisoning in hospitalized patients or to assist in an autopsy. - View all
- 9.33 Usage
- Methyl salicylate is used as a flavoring agent and providing fragrance to products like chewing gum and mints. It acts as an anticoagulant by interruption of the vitamin K1-epoxide cycle. It is also used in high concentrations as a rubefacient to treat joint, muscular pain and acute pain. It is utilized as an anti-herbivore defense system in various plants. It is used as a transfer agent to get a manual copy of an image on a surface and to clear plant or animal tissue samples to be used for microscopy.
