Title: Gaultherin
CAS Registry Number: 490-67-5
CAS Name: 2-[(6-O-b-D-Xylopyranosyl-b-D-glucopyranosyl)oxy]benzoic acid methyl ester
Synonyms: methyl salicylate-2-glucoxyloside; methyl salicylate-2-primeveroside; monotropitin; monotropitoside
Molecular Formula: C19H26O12
Molecular Weight: 446.40
Percent Composition: C 51.12%, H 5.87%, O 43.01%
Literature References: In the wintergreen plant, Gaultheria procumbens L., in Monotropa hypopitys L., Ericaceae in Betula lenta L., Betulaceae, in Spiraea ulmaria L. and S. filipendula L., Rosaceae: Bridel, Compt. Rend. 177, 642 (1923); 179, 991 (1924); 180, 1421, 1864 (1925); Bridel, Grillon, ibid. 187, 609 (1928). Synthesis: Robertson, Waters, J. Chem. Soc. 1931, 1881. On hydrolysis with 3% H2SO4 gaultherin forms 1 mol methyl salicylate, 1 mol D-glucose and 1 mol D-xylose. Enzymatic hydrolysis gives methyl salicylate and primeverose (glucoxylose).
