Malvin is a naturally occurring chemical of the Anthocyanin family. It is a diglucoside of malvidin mainly found as a pigment in herbs like Malva (Malva sylvestris) Primula and Rhododendron. The characteristic floral jade coloration of Strongylodon macrobotrys has been shown to be an example of copigmentation a result of the presence of malvin and saponarin (a flavone glucoside) in the ratio 1:9.
