Fig (Ficus carica L.) seeds are the less studied part of the species so far. They are usually discarded after their processing and scarcely studied for nutraceutical purposes. For this reason, the present work reports the lipochemical properties of fig seeds extracted from four fig cultivars conducted in an ex-situ collection. Oil was chemically extracted and screened using gas chromatography and FTIR-ATR coupled with chemometrics. Results, showed an important oil yield reaching up to 30 %, with a high UV absorbency values at 232 and 270 nm, suggesting the occurrence of hydrolytic reactions during the oil extraction. Iodine and saponification values were also high and displayed narrow ranges of variations (76.43 ± 0.067 g/100 g of oil and 201.6 ± 0.012, respectively). Chromatographic profile showed a high unsaturation rate up to 88 %, with a predominance of linolenic fatty acid, which ranged between 38.43 and 43.57 %. In order to avoid pollination effect, desaturation pathway ratios were calculated along with the balance between omega-6 and omega-3. These ratios showed statistically significant differences among samples and were in the range recommended for healthier diet. FTIR-ATR fingerprinting showed several spectral bands assigned to functional groups present in fig seed oil. Among them, two major peaks were identified around the fingerprint regions of 1650–1474 cm⁻¹ and 3010–2924 cm⁻¹ assigned to aliphatic groups and carbonyl groups belonging to the triacylglycerols, respectively. Data of both chromatographic profile and FTIR-ATR spectroscopy were involved in principal component analysis models, that showed high throughput resolution of discrimination and classification of samples studied. The findings herein reported, suggest the potential of fig seeds oil application in food and nutraceuticals. Besides, the use FTIR-ATR spectroscopy in fruit seeds screening and discrimination could be a better alternative to traditional analysis techniques.

无花果（无花果L.）种子是迄今为止该物种研究较少的部分。它们通常在加工后被丢弃，很少出于营养保健目的进行研究。因此，本工作报道了从异地采集的四个无花果品种中提取的无花果种子的脂化特性。化学提取油，并使用气相色谱和FTIR-ATR结合化学计量学进行筛选。结果表明，重要的油收率高达30％，在232和270 nm处具有很高的UV吸收值，表明在油提取过程中发生了水解反应。碘值和皂化值也很高，并且显示出狭窄的变化范围（分别为76.43±0.067 g / 100 g油和201.6±0.012）。色谱图显示不饱和率高达88％，以亚麻酸为主，占38.43％至43.57％。为了避免授粉效应，计算了去饱和途径比率以及omega-6和omega-3之间的平衡。这些比率在样本之间显示出统计学上的显着差异，并且处于为健康饮食所建议的范围内。FTIR-ATR指纹图谱显示了分配给无花果种子油中存在的官能团的几个光谱带。其中，在1650–1474 cm的指纹区域周围发现了两个主要峰 FTIR-ATR指纹图谱显示了分配给无花果种子油中存在的官能团的几个光谱带。其中，在1650–1474 cm的指纹区域周围发现了两个主要峰 FTIR-ATR指纹图谱显示了分配给无花果种子油中存在的官能团的几个光谱带。其中，在1650–1474 cm的指纹区域周围发现了两个主要峰^-1和3010-2924 cm ^-1分别分配给属于三酰基甘油的脂族基和羰基。色谱图和FTIR-ATR光谱数据都参与了主成分分析模型，该模型显示了对所研究样品的区分和分类的高通量分辨率。本文报道的发现表明，无花果籽油在食品和保健食品中的应用潜力。此外，将FTIR-ATR光谱技术用于水果种子的筛选和鉴别可能是传统分析技术的更好选择。
