Anthocyanins from the Berries of Haskaap, Lonicera caerulea L.

Abstract

The structural determination of five anthocyanins extracted from the berries of Haskaap, Lonicera caerulea L., was carried out by HPLC analysis, degradation and spectroscopic experiments. The two major pigments were established as cyanidin 3-glucoside and 3, 5-diglucoside. The minor two were identified as cyanidin 3-rutinoside and 3-gentiobioside, while the remaining one has not been identified yet.
