Determination of Bioactive Ingredients in Five Pumpkin Seeds Cuitivars

摘要

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 Y-aminobutyric acid (GABA) from the five types of pumpkin seeds cuitivars 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 a-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 tol5.53 mg/g. Results indicated that bioactive ingredients from Baokul exhibited the relatively higher values in all the cuitivars.
