Malonylated anthocyanin was isolated from the receptacle of 3 Japanese strawberries. The chemical structure was identified to be pelargonidin 3-O-(6-O-malonyl-β-D-glucoside) (1) mainly by 1H-NMR and FABMS. The anthocyanin content was about 30, 25, and 12% of total anthocyanins in Fragaria × ananassa Duch. cv. Nyoho, F. ananassa Duch. cv. Himesodachi and F. ananassa Duch. cv. Reiko, respectively. On the other hand, the cultivars Toyonoka and Ai-berry did not contain 1 at all.
