Constituents of tropical medicinal plants. Part 31. Flavonoid and other constituents of Bauhinia manca was written by Achenbach, Hans;Stoecker, Markus;Constenla, Manuel A.. And the article was included in Phytochemistry in 1988.Name: Methyl 4-Hydroxy-2-methoxybenzoate This article mentions the following:
Phytochem. anal. of the stem of B. manca yielded 63 compounds, among them 6 new natural products. The new products were identified as 4 flavonoids (isoliquiritigenin 4-Me ether, liquiritigenin 4′-Me ether, 7,3′-dimethoxy-4′-hydroxyflavan, 3′,4′-dihydroxy-7-methoxyflavan) and 2,4′-dihydroxy-4-methoxydihydrochalcone and the lignan (7S,8R,8′R)-5,5′-dimethoxylariciresinol. Major constituents were 3-O-galloylepicatechin, gallic acid, cinnamic acid, β-sitosterol, and its β-
Methyl 4-Hydroxy-2-methoxybenzoate (cas: 28478-46-8) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Name: Methyl 4-Hydroxy-2-methoxybenzoate
