摘要：
Pumpkin (Cucurbita pepo) seeds are used locally in Eritrea to treat tapeworm. Seeds were found to be rich in oil (similar to 35%), protein (38%), alpha-tocoferols (3 mg/100 g) and carbohydrate content (similar to 37%). The physico-chemical properties and fatty acid composition of the seed oil were examined. The four dominant fatty acids found are: palmitic C16:0 (13.3%), stearic C18:0 (8.0%), oleic C18:1 (29.0%) and linoleic C18:2 (47.0%). The oil contains an appreciable amount of unsaturated fatty acids (78.0%) and found to be a rich source of linoleic acid (47.0%). Within the three localities of the study, variations exist in seed properties and the fatty acid composition of the oil. (C) 2000 Elsevier Science Ltd. All rights reserved.
