To assess the antioxidant power (DPPH) of the pumpkin seed,
two types of extraction, hydrophilic and lipophilic, were conducted.
Hydrophilic extraction was performed with different
amounts (0.4–0.5 g) of homogenised pumpkin seeds, which were
dissolved with 6 ml methanol and water (80% v/v). The samples
were made subject to sonication for 15 min, followed by centrifugation
at 12,500 rpm for 5 min. The supernatant and precipitate of
each sample were recovered
