Epicatechin-(4beta->8)-epicatechin-(4beta->8)-catechin
Epicatechin-(4beta->8)-epicatechin-(4beta->8)-catechin is a member of the class of compounds known as biflavonoids and polyflavonoids. Biflavonoids and polyflavonoids are organic compounds containing at least two flavan/flavone units. These units are usually linked through CC or C-O-C bonds. Some examples include C2-O-C3, C2-O-C4, C3-C3, and C6-C8. Epicatechin-(4beta->8)-epicatechin-(4beta->8)-catechin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Epicatechin-(4beta->8)-epicatechin-(4beta->8)-catechin can be found in common grape, which makes epicatechin-(4beta->8)-epicatechin-(4beta->8)-catechin a potential biomarker for the consumption of this food product.
8-Glucopyranosylprocyanidin B2
Isolated from Chinese cinnamon bark (Cinnamomum cassia) and Rheum species (rhubarb). Procyanidin B2 8-C-glucoside is found in chinese cinnamon, herbs and spices, and green vegetables. 8-Glucopyranosylprocyanidin B2 is found in chinese cinnamon. 8-Glucopyranosylprocyanidin B2 is isolated from Chinese cinnamon bark (Cinnamomum cassia) and Rheum sp. (rhubarb).
Epifisetinidol-(4beta->8)-catechin
Epifisetinidol-(4beta->8)-catechin is found in fruits. Epifisetinidol-(4beta->8)-catechin is a constituent of Pithecellobium dulce (manila tamarino)
Epicatechin-(4beta->8)-catechin 3-gallate
Epicatechin-(4beta->8)-catechin 3-gallate is a member of the class of compounds known as biflavonoids and polyflavonoids. Biflavonoids and polyflavonoids are organic compounds containing at least two flavan/flavone units. These units are usually linked through CC or C-O-C bonds. Some examples include C2-O-C3, C2-O-C4, C3-C3, and C6-C8. Epicatechin-(4beta->8)-catechin 3-gallate is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Epicatechin-(4beta->8)-catechin 3-gallate can be synthesized from gallic acid. Epicatechin-(4beta->8)-catechin 3-gallate can also be synthesized into procyanidin B1. Epicatechin-(4beta->8)-catechin 3-gallate can be found in common grape, which makes epicatechin-(4beta->8)-catechin 3-gallate a potential biomarker for the consumption of this food product.
Epicatechin-(4beta->8)-epicatechin-(4beta->6)-epicatechin
Epicatechin-(4beta->8)-epicatechin-(4beta->6)-epicatechin is a member of the class of compounds known as biflavonoids and polyflavonoids. Biflavonoids and polyflavonoids are organic compounds containing at least two flavan/flavone units. These units are usually linked through CC or C-O-C bonds. Some examples include C2-O-C3, C2-O-C4, C3-C3, and C6-C8. Epicatechin-(4beta->8)-epicatechin-(4beta->6)-epicatechin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Epicatechin-(4beta->8)-epicatechin-(4beta->6)-epicatechin can be found in apple and common grape, which makes epicatechin-(4beta->8)-epicatechin-(4beta->6)-epicatechin a potential biomarker for the consumption of these food products.
