Abstract

The main purpose of this study was to determine the proximate composition and physicochemical properties of Algerian wild green carob collected from three separate locations in Jijel province (northeast of Algeria), as well as to investigate its antioxidant potency. The results showed that the three samples were substantially comparable in terms of proximate compositions and physicochemical attributes. They have an acidic pH range and a very low fat content. In terms of phytochemical properties, Texenna green pods had the highest levels of polyphenols, flavonoids, and flavonols, with concentrations of 87.10 ± 0.07 μg GAE/mg DM, 4.90 ± 0.06 μg QE/mg DM, and 37.0 ± 0.19 μg QE/mg DM, respectively. Furthermore, the total antioxidant capacity of the methanolic extracts was determined using the phosphomolybdate method and found to be 154.62 µg AAE/mg DM. These promising findings revealed that unripe Ceratonia siliqua L. from the Texenna region is a rich source of natural antioxidants that could be employed more broadly in functional food formulations.

阿尔及利亚野生绿角豆（Ceratonia siliqua L.）：理化特性和抗氧化能力

本研究的主要目的是确定从吉杰勒省（阿尔及利亚东北部）三个不同地点采集的阿尔及利亚野生绿角豆树的近似成分和理化特性，并研究其抗氧化能力。结果表明，这三种样本的近似成分和理化属性基本相当。它们的 pH 值呈酸性，脂肪含量很低。在植物化学特性方面，德克森纳青豆荚的多酚、类黄酮和黄酮醇含量最高，分别为 87.10 ± 0.07 μg GAE/mg DM、4.90 ± 0.06 μg QE/mg DM 和 37.0 ± 0.19 μg QE/mg DM。此外，采用磷钼酸盐法测定了甲醇提取物的总抗氧化能力，发现其为 154.62 µg AAE/mg DM。这些有前景的研究结果表明，德森纳地区未熟的 Ceratonia siliqua L. 是天然抗氧化剂的丰富来源，可更广泛地应用于功能性食品配方中。关键字：Ceratonia siliqua L.，未成熟豆荚，近似成分，理化性质，生物活性化合物，抗氧化效力 Bull.Chem.Soc.2024, 38(1), 187-198.DOI: https://dx.doi.org/10.4314/bcse.v38i1.14
