Wild jujube "." belongs to the Rhamnaceae family and is a traditionally herbaceous medicinal plant. It is very common in arid and semi-arid regions and is currently used for its antidiabetic, sedative, analgesic, anti-inflammatory and hypoglycemic activities. The aim of the present work was to characterize the physico-chemical properties and the phytochemical profile of wild jujube sample collected from the Guercif region, in order to determine the polyphenolic compounds and the antioxidant ability Analyses were carried out directly after the harvest for the determination of pH, refractive index, total soluble solid (°Brix), dry matter, sugar/acidity, total sugars, reducing sugars, as well as lipid and protein content. Results showed that the investigated fruit is acidic (pH 4.9 ± 0.23) and rich in sugars (80.2 g/100 g ± 3.81). The GC-MS analysis of the fruit revealed a number of volatile compounds, as many as 97, belonging to different chemical classes. The HPLC-DAD-ESI/MS analysis showed the presence of a total of 20 polyphenolic compounds in both EtOAc and MeOH-water extracts. Among them, -Hydroxybenzoic acid was the most abundant in the EtOAc extract (185.68 µg/100 mg ± 0.5) whereas Quercetin 3--rhamnoside-7--glucoside was found in higher amounts in the MeOH-water extract (25.40 µg/100 mg ± 0.5). These components have medical interest, notably for human nutrition, as well as health benefits and therapeutic effects. Therefore, Moroccan jujube "" fruit may have potential industrial applications for food formulations.
野生酸枣“。”属于鼠李科，是一种传统的草本药用植物。它在干旱和半干旱地区非常常见，目前用于其抗糖尿病、镇静、镇痛、抗炎和降血糖活性。本工作的目的是表征从盖尔吉夫地区采集的野生酸枣样品的物理化学性质和植物化学特征，以确定多酚化合物和抗氧化能力。在收获后直接进行分析，以确定 pH 值、折射率、总可溶性固体（°Brix）、干物质、糖/酸度、总糖、还原糖以及脂质和蛋白质含量。结果表明，所研究的果实呈酸性（pH4.9±0.23），富含糖分（80.2g/100g±3.81）。果实的 GC-MS 分析显示出许多挥发性化合物，多达 97 种，属于不同的化学类别。HPLC-DAD-ESI/MS 分析表明，EtOAc 和 MeOH-水提取物中总共存在 20 种多酚化合物。其中，-羟基苯甲酸在 EtOAc 提取物中含量最丰富（185.68µg/100mg±0.5），而槲皮素 3--鼠李糖苷-7--葡萄糖苷在 MeOH-水提取物中含量更高（25.40µg/100mg±0.5）。这些成分具有医学意义，特别是对人类营养以及健康益处和治疗效果。因此，摩洛哥酸枣“”果实可能具有食品配方的潜在工业应用。
