Abstract

Pelargonidin is one of the 19 anthocyanin types which have been found. Raspberry (Rubus rosifolius Sm) is a species of the Rubus genus from family of Rosaceae. In this research, characterization pelargonidin contained in extract of raspberries has been carried out by using HPLC-DAD-ESI-MS and also to apply the extract for drinks with different pH. The main pelargonidin contained in extract of raspberries is pelargonidin-3-rutinoside-5- malonylglucoside with a molecular ion of m/z 843 and base peak of 578 (pelargonidin-3-rutinoside). Anthocyanins from raspberry fruit extract can be applied as an alternative dyes in foods that have an acidic pH, as it gives a clear color.
