quinic การใช้

• Stenophyllanin A, a tannin, and other quinic acid gallates can be found in " Q . stenophylla ".
• In rats, theogallin, or its metabolite quinic acid, can move through the blood brain barrier and can have cognition enhancing activities.
• At the center of a hydrolyzable tannin molecule, there is a carbohydrate ( usually D-glucose but also cyclitols like quinic or shikimic acids ).
• Phenolics found in " Leontodon " include luteolin type flavonoids and caffeoyl quinic acid derivatives such as chlorogenic acid and 3, 5-dicaffeoylquinic acid.
• Hydrolysable tannins are mixtures of polygalloyl glucoses and / or poly-galloyl quinic acid derivatives containing in between 3 up to 12 gallic acid residues per molecule.
• Phenolics found in " Crepis " include luteolin-type flavonoids and caffeoyl quinic acid derivatives such as chlorogenic acid and 3, 5-dicaffeoylquinic acid.
• Phenolics found in flowering heads of " Scorzoneroides " taxa include luteolin type flavonoids and caffeoyl quinic acid derivatives such as chlorogenic acid and 3, 5-dicaffeoylquinic acid.
• In a recent study, 3-" trans "-caffeoyl-muco-quinic acid was found to be the substance that compelled spicebush swallowtails to lay their eggs on members of Lauraceae.
• However, 3-" trans "-caffeoyl-muco-quinic acid is a component of the extract from sassafras plants but not from spicebush, redbay or camphor tree, the other top three host plants of spicebush swallowtails.
• In addition, 3-" trans "-caffeoyl-muco-quinic acid is a member of a family of acids, hydroxycinnamic acids, which are present in oviposition stimulants for some members of all five families of swallowtail butterflies.
• Typical sourness of the fruits is due to high content of malic acid ( 0.8-3.2 g / 100 ml of juice ) while astringency is related to quinic acid ( 1.2-2.1 g / 100 ml of juice ).
• The chemical formula for commercial tannic acid is often given as C 76 H 52 O 46, which corresponds with decagalloyl glucose, but in fact it is a mixture of polygalloyl glucoses or polygalloyl quinic acid esters with the number of galloyl moieties per molecule ranging from 2 up to 12 depending on the plant source used to extract the tannic acid.
