Identification and analysis for anthocyanins compositions in strawberry

This paper is concerned on anthocyanin component characteristics in the strawberry variety.Liquid chromatography-mass spectrometry(HPLC-MS)and high performance liquid chromatography(HPLC-DAD)were applied to qualitative and quantitative analysis of anthocyanins in 17 strawberry cultivars.There were five main pigments of pelargonidin 3-glucoside,pelargonidin 3-rutinoside,pelargonidin-malonylglucoside,cyanidin 3-glucoside and pelargonidin 3-methylmalonylglucoside and 4 trace pigments of pelargonidin 3,5-diglucoside,5-carboxypyranopelargonidin-3-glucoside,cyanidin-malonylglucoside,pelargonidin-acetylglucoside in strawberry fruits.But the anthocyanin types,contents and proportions were different in different cultivars.The content of pelargonidin 3-glucoside was highest.Through principal component analysis of anthocyanins types and cluster analysis of cultivars,the strawberry cultivars were divided into 3rich anthocyanins type(RA),6high cyanins type(HC),6moderate anthocyanins type(MA)and 2low anthocyanin type(LC)according to total anthocyanin content,variety of anthocyanin and cyanins content.In summary,‘CAU 19-32'had the richest anthocyanins.,indicating that the improved with The new strawberry strains withabundant and rich anthocyanins could be obtained through breeding and selection techniques.
