10,172,772 B2 (Najla Guthrie, Robert Allen Guthrie); KGK Science, Inc., London, CA, has patented a method for lightening skin that entails topically applying to the skin a composition that consists of a canola extract comprising protocatechuic acid, vanillic acid, caffeic acid, syringic acid, P-coumaric acid, and sinapic acid (wherein the canola extract comprises at least 30% sinapic acid) and a cosmetically acceptable carrier.
The inhibition of Lu-cyclodextrin-CL reaction has been used for the characterization of five important therapeutic phenolic acids (ferulic acid, vanillic acid, gallic acid, protocatechuic acid and caffeic acid) with sulfobutyl ether-[beta]-cyclodextrin[128].
In addition to identifying downregulated metabolites, we found ten prominently upregulated metabolites, including trimethylamine-N-oxide (TMAO), pyridoxine, kinetin-9-riboside, p-coumaroyl-cinnamoyl-caffeoyl spermidine, vanillic acid, 3-sialyllactose, n-acetylvaline, l-valine, 3-chloro-l-tyrosine, and 3-methoxy-hydroxyphenyleneglycol sulfate (MHPG-SO4) in the ADR-induced FSGS group.
Plant-based phenolic compounds such as tocopherols, carotenoids, xanthines, gallic acid, caffeic acid, vanillin, sinapic acid, p-coumaric acid, eugenol, sesamol, vanillic acid, cinnamic acid and resveratrol have antioxidant properties and are produced commercially on a large scale.
Analysis of phenolic compounds: In the research, the gallic acid, catechin, chlorogenic acid, caffeic acid, syringic acid, p-coumaric acid, ferulic acid, o-coumaric acid, phloridzin, protocatechuic, vanillic acid, rutin and quercetin phenolic compounds were determined.
High-performance liquid chromatography showed that the phenolic compounds contained gallic acid, sinapic acid, vanillic acid, syringic acid, protocatechuic acid, p-coumaric acid, chlorogenic acid, caffeic acid and ferulic acid.
The standards used were gallic acid, salicylic acid, catechin, ellagic acid, quercetin, vanillin, eugenol, and vanillic acid.
Stock standard solutions were prepared by accurately weighing 10 mg of caffeic acid, chlorogenic acid, p-coumaric acid, trans-ferulic acid, cinnamic acid, quercetin, luteolin, apigenin, rutin, vanillic acid, syringic acid, o-coumaric acid, catechin, vanillin, trans-chalcone, 4-hydroxybenzoic acid, 2-(4-hydroxyphenyl)ethanol, and 3,4-dihydropyran reference standards into separate 2 ml volumetric flasks and dissolving in methanol.
