Phytochemical and Nutritional Profile Composition in Fruits of Different Sweet Chestnut (Castanea sativa Mill.) Cultivars Grown in Romania

Chestnut (Castanea sativa Mill.), a valuable fruit crop, is cultivated in small areas Romania, mostly the west, where moderate continental climate has slight Mediterranean influence. This work aims to investigate bioactive characteristics (total polyphenols, total flavonoids and antioxidant activity), individual polyphenolic composition, phytochemical nutritional HRMS screening profiles, sugar mineral composition of six sweet chestnut cultivars, namely ‘Marsol’, ‘Maraval’, ‘Bournette’, ‘Précoce Migoule’ ‘Marissard’ grown at Fruit Growing Research—Extension Station (SCDP) Vâlcea, Northern Oltenia, Romania. samples were collected two consecutive years, order study impact genetic variability between cultivars influence different climatic conditions corresponding cultivation years. Principal Component Analysis (PCA) Hierarchical Cluster (HCA) allow discrimination fruits harvested years cultivars. Analytical investigations revealed that Romania show similar bioactive, large European chestnut-producing countries, indicating high adaptation potential temperate zone with influences characteristic southwestern area
