Abstract: The main aim of this study was to investigate the major changes in the content of bioactive components during storage of the great pumpkin’s fruit flesh. Three great pumpkins varieties 'Justynka', 'Karowita' and 'Amazonka' were grown in ecological farm in Kaunas district. All seedlings were planted on May 18, 2012 and harvested in late September. Fully matured pumpkin fruit, were stored in a room where the temperature was 13–14 °C, relative air humidity - 70%. The great pumpkins were storaged for 4 months. Our results confirmed the results of other researchers, that the content of ascorbic acid, dry matter and soluble solids in pumpkins decreases with increasing storage time. At the beginning of the storage period the highest amount of ascorbic acid (7.73 mg g-1) was identified in 'Amazonka' pumpkins. After four months of storage, the lowest content of ascorbic acid (1.76 mg g-1) was found in the flesh of 'Justynka' variety. Significantly maximum dry matter value (15.8%) was fixed in 'Justynka' variety in October. In the end of storage period, the minimum amount of dry matter was found in 'Amazonka' pumpkins – 6.37%. The soluble solids degradation was influenced by storage period. The significantly highest quantity of the soluble solids (11.1%) was found in 'Justynka' pumpkins in October - the beginning of the storage period, while the minimum (2.13%) of these materials existed in 'Justynka' variety, in the end of holding period
