Catechin 7-xyloside
Leucopelargonidin
Leucopelargonidin (CAS: 520-17-2) is a colourless chemical compound belonging to the family of leucoanthocyanidins. Leucoanthocyanidins are flavonoids consisting of a flavan (3,4-dihydro-2-phenyl-2H-1-benzopyran) moiety that carries two hydroxy groups at the C3- and C4-positions. Leucopelargonidin is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Leucopelargonidin can be found in a number of food items such as narrowleaf cattail, pepper (C. pubescens), macadamia nut (M. tetraphylla), and abiyuch, which makes leucopelargonidin a potential biomarker for the consumption of these food products (FooDB). Leucopelargonidin can also be found in Albizia lebbeck (East Indian walnut), in the fruit of Anacardium occidentale (cashew), in the fruit of Areca catechu (Areca nut), in the fruit of Hydnocarpus wightiana (Hindi Chaulmoogra), in the rhizome of Rumex hymenosepalus (Arizona dock), in Zea Mays (corn), and in Ziziphus jujuba (Chinese date) (Wikipedia).
