Some date palm cultivars grown in Pakistan were biochemically characterized and the effect of fruit maturity on radical
scavenging capacity (DPPH), total phenolic contents (TPC), specific activity of antioxidant enzymes, sugars profile and
soluble protein contents was assessed. Higher range of differences in composition of studied phytochemicals was recorded
among different cultivars. Antiradical efficiency (AE), TPC, antioxidant enzymes and soluble protein contents were recorded
higher at khalal stage thereafter, declined at rutab then finally at tamar stage. The amount of glucose (11.32-32.50%) and
fructose (10.95-32.41%) started accumulation from khalal stage and were in higher composition at tamar stage due to
hydrolysis and inversion of sucrose (10.82-3.1%) contents. The results concluded that variation in biochemical attributes
primarily influenced by type of cultivars and different fruit developmental stages.
