Bicornin is an ellagitannin found in plants of the order Myrtales, including Trapa bicornis (water caltrop) [1] and Syzygium aromaticum (clove). [2]
The molecule contains a luteic acid group. [3]
Tannins are a class of astringent, polyphenolic biomolecules that bind to and precipitate proteins and various other organic compounds including amino acids and alkaloids.
The water caltrop is any of three extant species of the genus Trapa: Trapa natans, Trapa bicornis and the endangered Trapa rossica. It is also known as buffalo nut, bat nut, devil pod, ling nut, mustache nut, singhara nut or water chestnut.
The Biginelli reaction is a multiple-component chemical reaction that creates 3,4-dihydropyrimidin-2(1H)-ones 4 from ethyl acetoacetate 1, an aryl aldehyde, and urea 3. It is named for the Italian chemist Pietro Biginelli.
Camphorsulfonic acid, sometimes abbreviated CSA or 10-CSA is an organosulfur compound. Like typical sulfonic acids, it is a relatively strong acid that is a colorless solid at room temperature and is soluble in water and a wide variety of organic substances.
Coumestan is a heterocyclic organic compound. Coumestan forms the central core of a variety of natural compounds known collectively as coumestans. Coumestans are oxidation products of pterocarpan that are similar to coumarin. Coumestans, including coumestrol, a phytoestrogen, are found in a variety of plants. Food sources high in coumestans include split peas, pinto beans, lima beans, and especially alfalfa and clover sprouts.
Chymotrypsin-like elastase family member 3A is an enzyme that in humans is encoded by the CELA3A gene.
Cornus officinalis, the Japanese cornel or Japanese cornelian cherry, is a species of flowering plant in the dogwood family Cornaceae. Despite its name, it is native to China and Korea as well as Japan. It is not to be confused with C. mas, which is also known as the Cornelian cherry. It is not closely related to the true cherries of the genus Prunus.
Tectorigenin is an O-methylated isoflavone, a type of flavonoid. It ha been isolated from leopard lily, Algerian iris and East Asian arrowroot.
Casuarictin is an ellagitannin, a type of hydrolysable tannin. It can be found in Casuarina and Stachyurus species.
Stachyurus is the only genus in the flowering plant family Stachyuraceae, native to the Himalayas and eastern Asia. They are deciduous shrubs or small trees with pendent racemes of 4-petalled flowers which appear on the bare branches before the leaves. The plants have leaves with serrate margins.
Tellimagrandin II is the first of the ellagitannins formed from 1,2,3,4,6-pentagalloyl-glucose. It can be found in Geum japonicum and Syzygium aromaticum (clove).
Quercus infectoria or the Aleppo oak is a species of oak well known for producing galls that have been traditionally used for centuries in Asia medicinally while also used in softening leather and in making black dye and ink.
Casuarinin is an ellagitannin. It is found in the pericarp of pomegranates. It is also found in Casuarina and Stachyurus species and in Alnus sieboldiana.
Pedunculagin is an ellagitannin. It is formed from casuarictin via the loss of a gallate group.
Luteic acid is a natural phenol found in numerous fruits. It is a monolactonized tergalloyl group. Maximilian Nierenstein showed in 1945 that luteic acid was a molecule present in the myrobalanitannin, a tannin found in the fruit of Terminalia chebula and is an intermediary compound in the synthesis of ellagic acid. It can form from hexahydroxydiphenic acid. It is also present in the structure of the tannins alnusiin and bicornin.
Alnusiin is an ellagitannin found in Alnus sieboldiana.
Alnus sieboldiana is an alder species found on the islands of Honshū, Shikoku, and Suwanose-jima in Japan.
Geraniin is a dehydroellagitannin found in geraniums. It is found for instance in Geranium thunbergii, which is one of the most popular folk medicines and also an official antidiarrheic drug in Japan. It can also be found in the rind of Nephelium lappaceum (rambutan).
Mallotus japonicus, also known as East Asian mallotus, the food wrapper plant or "Akamegashiwa" in Japanese, is a plant species in the genus Mallotus native to China. It is also found in Japan and Korea. This species was first described in 1865, its name was verified by AAS Systematic Botanists on October 2, 2015.
Monochaetum multiflorum is a flowering plant species in the genus Monochaetum indigenous to Colombia.
