In these studies, the berries of different Polish cultivars of blue honeysuckle and food products based on these fruits were analyzed for nutritional, flavor and bioactive components. Characterization of the aroma profile of berries was achieved by solid-phase microextraction coupled with comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry (GC�GC-TOFMS). Important flavor compounds previously described in blueberries, including aliphatic esters, �green leaf volatiles� and terpenes, were also found in this study. The berries were found to contain 46 terpenes identified by GC�GC-TOFMS. 12 of the detected terpenes, especially a-pinene, �-myrcene, geraniol, eucalyptol, linalool, limonene and a-terpineol are partially responsible for healing properties of L. caerulea berries. The major bioactive terpene in the blue honeysuckle berries was eucalyptol, which ranged from 12.4 to 418.2 �g/l. The results obtained by capillary isotachophoresis showed that blue honeysuckle and berry products are good source of potassium (200 � 400 mg/100g fw), especially Zielona and Zojka cultivars.
