Ethanol and n-hexane were employed to extract hemp seed oil, a potential edible vegetable oil with a rare ideal ratio of ω-6/ω-3 fatty acid (3:1). A Central Composite Design (CCD) 2² was used to investigate the influence of Temperature (T) and Solvent/Seed Mass Ratio (SSMR) on the hemp seeds oil yield, evaluating the influence of the time extraction. In the best conditions, the fatty acids and triacylglycerol (TAG) profiles, density and dynamic viscosity temperature profiles (293.15 to 343.15 K), and the total Carotene and Chlorophyll content were studied. The best T, SSMR and extraction time for n-hexane and ethanol were 343.15 K, 7/1 and 6 h, and 348.15 K, 7/1 and 6 h, respectively, presenting a maximum oil yield of 32.1% (n-hexane) and 17.3% (ethanol). A high degree of unsaturation (> 90%) was observed, with a predominance of polyunsaturated fatty acids. The TAG LLL (L–Linoleic acid) was the most abundant with approximately 15% of the total oil composition for both solvents used in the extraction. The ideal ω-6/ω-3 ratio was observed for the extraction with both solvents (3.21 for n-hexane and 3.18 for ethanol). The density and viscosity temperature profile presented similarities with other common vegetable oils. The total chlorophyll content was 61.22 μg/g and 16.12 μg/g for hemp seed oil extracted with ethanol and n-hexane, respectively. Total Carotene content was higher for the oil extracted with ethanol (17.23 µg/g of oil) compared to n-hexane (4.40 µg/g of oil). Hemp seed oil can therefore be an important source of lipids in human foods with properties close to common vegetable oils and good nutritional potential, allowing its use for different purposes.

采用乙醇和正己烷提取大麻籽油，这是一种潜在的食用植物油，具有罕见的理想脂肪酸比例（3:1）的ω-6/ω-3。中央复合设计 (CCD) 2 ²采用温度（T）和溶剂/种子质量比（SSMR）对大麻籽出油率的影响，评估提取时间的影响。在最佳条件下，研究了脂肪酸和三酰甘油 (TAG) 曲线、密度和动态粘度温度曲线（293.15 至 343.15 K）以及总胡萝卜素和叶绿素含量。正己烷和乙醇的最佳 T、SSMR 和提取时间分别为 343.15 K、7/1 和 6 h，以及 348.15 K、7/1 和 6 h，最大油收率为 32.1%（正己烷） ）和 17.3%（乙醇）。观察到高度不饱和度（> 90%），其中多不饱和脂肪酸占主导地位。对于提取中使用的两种溶剂，TAG LLL（L-亚油酸）含量最丰富，约占总油成分的 15%。使用两种溶剂提取时观察到理想的 ω-6/ω-3 比率（正己烷为 3.21，乙醇为 3.18）。密度和粘度温度曲线与其他常见植物油相似。乙醇和正己烷提取的大麻籽油的总叶绿素含量分别为61.22 μg/g和16.12 μg/g。与正己烷（4.40 µg/g 油）相比，用乙醇提取的油的总胡萝卜素含量（17.23 µg/g 油）更高。因此，大麻籽油可以成为人类食品中脂质的重要来源，其特性接近普通植物油，并且具有良好的营养潜力，可用于不同的用途。密度和粘度温度曲线与其他常见植物油相似。乙醇和正己烷提取的大麻籽油的总叶绿素含量分别为61.22 μg/g和16.12 μg/g。与正己烷（4.40 µg/g 油）相比，用乙醇提取的油的总胡萝卜素含量（17.23 µg/g 油）更高。因此，大麻籽油可以成为人类食品中脂质的重要来源，其特性接近普通植物油，并且具有良好的营养潜力，可用于不同的用途。密度和粘度温度曲线与其他常见植物油相似。乙醇和正己烷提取的大麻籽油的总叶绿素含量分别为61.22 μg/g和16.12 μg/g。与正己烷（4.40 µg/g 油）相比，用乙醇提取的油的总胡萝卜素含量（17.23 µg/g 油）更高。因此，大麻籽油可以成为人类食品中脂质的重要来源，其特性接近普通植物油，并且具有良好的营养潜力，可用于不同的用途。
