摘要

枸杞是茄科植物枸杞(Lycium barbarum L.)的果实,枸杞的种植在全球范围内不断扩大,欧洲也不例外。本研究对塞尔维亚不同地区枸杞的营养价值、化学成分和体外生物活性进行了比较分析。根据标准方法对近似成分进行了评估。矿物质通过电感耦合等离子体技术进行评估,脂肪酸、甾醇和酚类物质则通过气相和液相色谱法结合火焰离子化法、质谱法或二极管阵列检测法进行分析。酚类、类黄酮、类胡萝卜素和多糖的总含量采用分光光度法进行评估。对 GB 的甲醇提取物进行了抗氧化、酶抑制(α-淀粉酶、α-葡萄糖苷酶、乙酰胆碱酯酶和酪氨酸酶)和抗菌活性检测。尽管不同地区的样本之间存在很大差异,但研究结果证实,GB 是膳食纤维和蛋白质的重要来源,并具有良好的脂肪酸特征。植物化学分析显示,β-谷甾醇、Δ5-芒柄甾醇和 24-甲基去甾醇是主要的甾醇,咖啡酸、没食子酸、槲皮素和芦丁是主要的酚类。所有国标样品都具有抗氧化和温和的抗菌活性。抗酶活性呈剂量依赖性(IC50 为 1.68-6.88 mg/mL)。这些结果支持在塞尔维亚进一步推广 GB 栽培,并进一步研究其在各行业中的潜在应用。

Nutritional Value, Phytochemical Composition and Biological Activities of Lycium barbarum L. fruits from Serbia.

Cultivation of goji berries (GB), fruits of Lycium barbarum L. (Solanaceae), is expanding worldwide, including in Europe. In this study, a comparative analysis of the nutritional value, chemical composition and in vitro biological activities of GB from different locations in Serbia was performed. Proximate compositions were evaluated according to standard methods. Minerals were assessed by inductively coupled plasma techniques, while fatty acids, sterols, and phenolic profiles were analyzed by gas- and liquid chromatography-based techniques coupled with flame-ionization, mass spectrometry, or diode array detection. The total content of phenolics, flavonoids, carotenoids, and polysaccharides was assessed using spectrophotometric methods. Methanol extracts from GB were examined for their antioxidant, enzyme inhibitory (α-amylase, α-glucosidase, acetylcholinesterase and tyrosinase) and antibacterial activities. Despite significant variations among samples from different locations, the results confirmed that GB are a valuable source of dietary fiber and protein and are characterized by favorable fatty acid profiles. Phytochemical analysis revealed that β-sitosterol, Δ5-avenasterol, and 24-methyldesmosterol are the predominant sterols and caffeic acid, gallic acid, quercetin and rutin are the main phenols. All GB samples showed both antioxidant and mild antimicrobial activity. A dose-dependent anti-enzymatic activity (IC50 ranging 1.68-6.88 mg/mL) was demonstrated. The results support further promotion of GB cultivation in Serbia and further investigations on their potential applications in various industries.
