Malvin

Malvin is a naturally occurring chemical of the anthocyanin family.

Malvin reacts in the presence of H2O2 to form malvone.

[2] The ortho-benzoyloxyphenylacetic acid esters reaction product is dependant of the pH: it is obtained under acidic conditions whereas under neutral conditions, the reaction product is the 3-O-acyl-glucosyl-5-O-glucosyl-7-hydroxy coumarin.

[3] It is a diglucoside of malvidin mainly found as a pigment in herbs like Malva (Malva sylvestris), Primula and Rhododendron.

[5] 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.
