Description | Proanthocyanidin A-6 belongs to the class of organic compounds known as biflavonoids and polyflavonoids. These 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''. Proanthocyanidin A-6 is found in Aesculus hippocastanum , Parameria laevigata MOLDENKE and Parameria laevigata MOLDENKE . It was first documented in 2014 (PMID: 25356846). Proanthocyanidin A-6 is a moderately basic compound (based on its pKa) (PMID: 30043588) (PMID: 29716563) (PMID: 26051626) (PMID: 25911741). |
