Anthocyanins are compounds related to the color of plants. They also have beneficial effects on human health and are used as a supplement. Various species of anthocyanins, divided by their molecular shape, are present in plants. Therefore, simple, and rapid, analytical techniques that can distinguish among these species in crops are necessary for breeding and quality assessment. A team of Nagoya University researchers in Japan has used a technique called probe electrospray ionization tandem mass spectrometry (PESI/MS/MS) to analyze anthocyanins in crops. Their results were published in the journal Horticulture Research.
