Determination of anthocyanins in four Croatian cultivars of sour cherries (Prunus cerasus)
- 449 Downloads
The anthocyanins were characterised and quantified in four cultivars of sour cherries by means of high-performance liquid chromatography and mass spectrometry. Column chromatography on XAD-2 Amberlite was the method used for isolation of anthocyanins. A diode-array detector was employed. For anthocyanins determination was chosen wavelength of 518 nm. Cyanidin-3-glucosylrutinoside and cyanidin-3-rutinoside were major anthocyanins. The total anthocyanin content in sour cherries, (expressed as cyanidin-3-glucosylrutinoside) varied from 2.7 to 28.0 mg/100 g of fresh weight, with the highest content being observed in Oblačinska cultivar.
