The proximate composition and physico-chemical properties (moisture, crude lipid, crude protein, ash, and crude fiber, peroxide value, saponification value, acidity, relative density and refractive index) of prickly pear seed and corresponding oil were determined. The mineral contents (Ca, Cu, Fe, K, Mg, Na, P, Mn and Zn) of samples were analyzed by inductively coupled plasma atomic emission spectrometry. Minerals determined were: calcium 471.2 mg/kg, potassium 532.7 mg/kg, magnesium 117.3 mg/kg, phosphorus 1,627.5 mg/kg and natrium 71.3 mg/kg. The fatty acid profiles of seed oil from the Opuntia ficus indica were analyzed by gas chromatography. Linoleic acid was established as the major fatty acid (61.01%), followed by oleic (25.52%) and palmitic (12.23%) acids. Both myristic, stearic and arachidonic acids were detected in O. ficus indica seed oil in low amounts. As a result, O. ficus indica seeds are an important source of natural fiber and, given its high linoleic acid content, its oil can be used as a nutraceutic agent.
测定了仙人掌种子及其相应油的近似成分和理化性质（水分、粗脂肪、粗蛋白、灰分、粗纤维、过氧化物值、皂化值、酸值、相对密度和折射率）。采用电感耦合等离子体原子发射光谱法对样品中的矿物质含量（Ca、Cu、Fe、K、Mg、Na、P、Mn 和 Zn）进行了分析。测定的矿物质有：钙 471.2mg/kg、钾 532.7mg/kg、镁 117.3mg/kg、磷 1627.5mg/kg 和钠 71.3mg/kg。采用气相色谱法分析了仙人掌籽油的脂肪酸组成。亚油酸被确定为主要脂肪酸（61.01%），其次是油酸（25.52%）和棕榈酸（12.23%）。在仙人掌籽油中还检测到少量的肉豆蔻酸、硬脂酸和花生四烯酸。因此，仙人掌种子是天然纤维的重要来源，鉴于其亚油酸含量高，其油可用作营养药物。
