This study was conducted to investigate the constituents of pumpkin and sweet-pumpkin. Moisture content of pumpkin was higher than that of sweet-pumpkin, but the other proximate constituents were lower. The major free amino acids were aspartic acid, threonine and cystine in pumpkin and cystine, arginine and tyrosine in sweet-pumpkin. Non-volatile organic acid of sweet-pumpkin was higher than that of pumpkin. Crude fat content of pumpkin and sweet-pumpkin were 0.33% and 0.48%. The major fatty acids were palmitic acid, linolenic acid and linoleic acid in pumpkin and oleic acid, linoleic acid and palmitic acid in sweet-pumpkin. The content of unsaturated fatty acid was 52.3%, 71.5% in pumpkin and sweet-pumpkin, respectively. The contents of minerals, vitamin C and carotenoid in sweet-pumpkin were higher than those of pumpkin.
