Malvin

Malvin is a naturally occurring chemical of the anthocyanin family.

Malvin reacts in the presence of H2O2 to form malvone. 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.

Natural occurrences
It is a diglucoside of malvidin mainly found as a pigment in herbs like Malva (Malva sylvestris), Primula and Rhododendron. M. sylvestris also contains malonylmalvin (malvidin 3-(6-malonylglucoside)-5-glucoside).

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.

Presence in food
Malvin can be found in a variety of common foods, including peaches (Clingstone variety ).
