Abstract/OtherAbstract:
Strawberry cultivars grown at different locations in Europe showed genotype- and environment-dependent variation in total phenol and anthocyanin content. This study focused on the compositional diversity of tannins from these cultivars using a high-through-put liquid-chromatography-mass-spectrometric (LCMS) technique. Cultivars grown in Germany showed differences in the relative amounts of proanthocyanidins (PACs) and ellagitannins (ETs). Cultivars grown at 3 different European locations showed differences in their PAC/ET balance. 'Elsanta' grown in Switzerland had higher levels of ET-derived than PAC-derived signals compared to 'Elsanta' grown in Germany and Denmark. The trend to increased ET-derived signals was also noted for 'Clery' grown in Switzerland over Germany, and was apparent for 'Korona' grown in Denmark over Germany. The altered ET/PAC balance was confirmed by conventional LCMS analysis which highlighted specific changes in composition rather than a general increase in ET components. These findings are discussed with respect to the environmental conditions at the different European locations.
