Abstract

Opuntia ficus-indica is well-known in Algeria for its nutritional and therapeutic properties. Our study aims to determine the physicochemical properties, the functional groups and the antioxidant activity of cactus seed oil and thus contribute to the valorization of seeds.  The extraction of prickly pear seed oil with cold-press provided a yield of 4.26± 0.93%. The evaluation of the its physicochemical parameters by the norms of AFNOR yielded the following results: density: 0.908± 0.00030 kg/dm; RI: 1.4714±0,00010; AV: 1.4± 0.09 mg KOH/g; IV: 114.08± 0.67 g I 2 /100 g; SV: 188.94± 0.58 mg KOH / g; ES: 187.54±0.49 mg KOH/g; PV: 1.56 g O2 /g; chlorophyll number: 1.076 and Carotenoids number: 0.315. FTIR spectrum was used to determine the functional groups and type of associated vibrations in the extract oil, which was scanned in the range (4000-400) cm -1. The FTIR results showed that the oil extract contains fatty acid methyl esters, revealing functional groups with ranges of properties, H- C = O, -(CH2) n -, C-O, C = C and C = O in the spectrum. The analysis of antioxidant activity using DPPH and FRAP methods showed that the OFI seed oil had a significant activity in capturing free radicals (IC50= 0.050 mg/mL), (EC50 = 0.123 mg/mL) respectively. We conclude from this current study that this oil can be used in folk medicine.

阿尔及利亚特贝萨地区仙人掌籽油的FTIR分析及理化参数和抗氧化活性研究
仙人掌在阿尔及利亚因其营养和治疗特性而闻名。我们的研究旨在确定仙人掌籽油的理化性质、官能团和抗氧化活性,从而有助于种子的增值。采用AFNOR标准对其理化参数进行评价,结果表明:密度:0.908±0.00030kg/dm;RI:1.4714±000010;AV:1.4±0.09 mg KOH/g;IV: 114.08±0.67 g I2/100 g;SV:188.94±0.58mg KOH/g;ES:187.54±0.49 mg KOH/g;PV:1.56 g O2/g;叶绿素数:1.076,类胡萝卜素数:0.315。FTIR光谱用于测定萃取油中的官能团和相关振动类型,扫描范围为(4000-400)cm-1。FTIR结果表明,该油提取物含有脂肪酸甲酯,在光谱中显示出具有一定性质的官能团,如H-C=O、-(CH2)n-、C-O、C=C和C=O。DPPH法和FRAP法的抗氧化活性分析表明,OFI籽油具有显著的自由基捕获活性(IC50=0.050 mg/mL),(EC50=0.123 mg/mL)。我们从目前的研究中得出结论,这种油可以用于民间医药。
