Methyl salicylate (oil of wintergreen) is used as a flavoring agent and it is also used in rubbing compounds, like Ben Gay. ISO 21390:2005 specifies certain characteristics of the oil of wintergreen, China [Gaultheria yunnanensis (Franch.)Rehd. After ingestion, methyl salicylate is readily metabolized by the body to salicylic acid, which is the same bioactive intermediate as in aspirin. C OH O OCH3. Therefore, just as aspirin can be toxic, so too can wintergreen ess… The potent molecule, methyl salicylate, is structurally similar to aspirin (acetylsalicylic acid). When mixed with sugar and dried, it is a potentially entertaining source of triboluminescence, gaining the tendency to build up electrical charge when crushed or rubbed, which can be observed by crushing wintergreen Life Savers in a dark room. Methyl salicylate. Wintergreen oil is usually obtained from the genus Gaultheria, most commonly from the two wintergreen species Gaultheria procumbens and Gaultheria fragrantissima (Nikolić, et al., 2013). Trends in floral scent chemistry in pollination syndromes: floral scent composition in moth-pollinated taxa. 16 - How does the structure of aspirin differ from that... Ch. Aspirin is the ester of salicylic acid and acetic acid (acetyl salicylic acid), whereas oil of wintergreen is the ester of salicylic acid and methanol (methyl salicylate). Wintergreen essential oil is derived from the leaves of the Gaultheria Procumbens evergreen plant using a steam distillation method. Coming to the oil of wintergreen structure, this syrupy tasting member of the family of aspirins is probably one of the most extensively utilised counter-irritants in the market.

Methyl salicylate is potentially deadly, especially for young children. First the leaves are steeped in a bit of warm water, releasing all of the beneficial enzymes locked within the leaf, and then the enzymes are isolated and concentrated to create the essential oil using a steam distillation process. Although well known for its therapeutic effects, wintergreen is not without its hazards. structure of an ester. The difference comes down to chemistry and ion channels.
