摘要

摘要。用石油醚提取南瓜籽油，并对其脂肪酸组成和理化参数进行了分析。发现种子含有43.6%（%w/w）的油。南瓜籽油中主要脂肪酸为亚油酸（50.7%）、油酸（18.8%）、棕榈酸（17.9%）和硬脂酸（12.4%）。南瓜籽油的理化参数为酸值（1.32 mg KOH/g油）、皂化值（191 mg KOH/g油）、碘值（114 g I2/100 g）、过氧化值（3.6 meq/kg）、比重（0.91 g/mL）、折射率（1.47）和粘度（24.7）。根据研究结果，50%的南瓜籽油含有必需脂肪酸ω-6（亚油酸）。南瓜籽油中含有高浓度的必需亚油酸，这意味着它是一种营养丰富的食物。南瓜籽油样品的物理化学研究还表明，它们适合作为工业原料，用于制造肥皂、化妆品、药物和食品添加剂等。关键词：南瓜籽油，脂肪酸，含油量，理化参数，气相色谱-质谱法，埃塞俄比亚公牛。化学。Soc.Ethiop。2023，37（3），565-577.DOI:https://dx.doi.org/10.4314/bcse.v37i3.3

Determination of fatty acids composition by GC-MS and physicochemical parameters of pumpkin (Cucurbita maxima) seed oil cultivated in Ethiopia

ABSTRACT. Pumpkin (Cucurbita maxima) seed oil was extracted using petroleum ether and analyzed for fatty acid compositions and physicochemical parameters of the oil. The seeds were found to contain 43.6% (%w/w) oil. Linoleic (50.7%), oleic (18.8%), palmitic (17.9%) and stearic (12.4%) were found as the primary fatty acids in pumpkin seed oil. Physicochemical parameters of pumpkin seed oil were found to be acid value (1.32 mg KOH/g oil), saponification value (191 mg KOH/g oil), iodine value (114 g I2/100 g), peroxide value (3.6 meq/kg), specific gravity (0.91 g/mL), refractive index (1.47) and viscosity (24.7). According to the study's findings, 50% of the oil contains the essential fatty acid omega-6 (linoleic acid). The high concentration of essential linoleic acid in pumpkin seed oil implies that it is a nutrient-dense food. The physicochemical study of the pumpkin seed oil samples also showed that they were suitable as industrial ingredients for making soap, cosmetics, medications, and food additives, among other things.
