Quality assessment of 178 cultivars of plum regarding phenolic, anthocyanin and sugar content

In this study assessment of total phenolic, individual anthocyanin and total sugar content (TSC) of wide range of plum cultivars was done in order to select cultivars with high health benefiting compounds for potential breeding purposes. Total phenolics varied between 38.45 and 841.50mg GAE 100g(-1) FW. Cyaniding-3-rutinoside, cyaniding-3- glucoside and its equivalents were identified in anthocyanin measurement by HPLC with different ranges. TSC differed between 9.63 and 29.47%. Besides, evaluation of the effect of cultivar and year on phenolic content of 23 randomly selected cultivars over two following years (2013 & 2014) showed significant effect of both factors on phenolic content of plum cultivars. Overall, cultivars "Cacaks Spaete" which had high amount of total phenolics with stability over time, as well as "Hohenheim breed 4894" as a cultivar which contained high amounts of total phenolics, anthocyanins and TSC were selected for further breeding purposes to provide high nutritional quality plum to consumers.
