Determination of Bioactive Ingredients in Five Pumpkin Seeds Cultivars

Abstract:

Pumpkin is a widely cultivated vegetable used for human consumption and traditional medicine this investigation will provide much more information for the further exploration of pumpkin seeds. In the present study, the contents of total phenolics, phytosterols, squalene, α-tocopherol, polysaccharides and γ-aminobutyric acid (GABA) from the five types of pumpkin seeds cultivars were determined by established methods. The total phenolics contents of the pumpkin seeds ranged from 0.96 to 2.52 mg/g, total phytosterols contents ranged from 2.02 to 2.65 mg/g, while the levels of squalene and α-tocopherol detected ranged from 0.92 to 1.29 mg/g and 83.09 to 98.57µg/g, respectively. Polysaccharides were the most abundant constituents, ranging in concentration from 119.42 to 143.77 mg/g, GABA was also present in significant concentrations ranged from 3.71 to15.53 mg/g. Results indicated that bioactive ingredients from Baoku1 exhibited the relatively higher values in all the cultivars.
