The environmental impact of invasive species necessitates creating a strategy for managing their spread by utilising them as a source of potentially high-value raw materials. (Lam.) K. Koch (dwarf serviceberry) is a shrub species in the Juss. family. The evaluation of different populations of plants that accumulate great amounts of biologically active compounds is requisite for the quality determination of plant materials and medicinal and nutritional products. The assessment of natural resources from a phytogeographic point of view is relevant. Phytochemical analysis of leaf samples was carried out using spectrophotometric methods, HPLC-PDA, and HPLC-MS techniques, while antioxidant activity was determined using ABTS, FRAP, and CUPRAC assays. A significant diversification of phenolic compounds and antioxidant activity was determined in the leaf samples collected in different habitats. Due to their characteristic chemical heterogeneity, natural habitats lead to the diversity of indicators characterising the quality of plant raw materials. Chlorogenic acid and neochlorogenic acid, as well as quercitrin, rutin, and hyperoside, were found to be predominant among the phenolic compounds. Thus, these compounds can be considered phytochemical markers, characteristic of the leaf material from northern Europe.
入侵物种对环境的影响使得有必要制定一项管理其扩散的策略，即把它们作为潜在高价值原材料的来源加以利用。（Lam.）K. Koch（矮沙棘）是蔷薇科的一种灌木物种。评估积累大量生物活性化合物的不同植物种群对于确定植物材料以及药用和营养产品的质量是必要的。从植物地理学角度评估自然资源具有重要意义。使用分光光度法、高效液相色谱 - 光电二极管阵列检测法（HPLC - PDA）和高效液相色谱 - 质谱联用技术（HPLC - MS）对叶片样本进行了植物化学分析，同时使用ABTS、FRAP和CUPRAC法测定了抗氧化活性。在不同生境采集的叶片样本中，确定了酚类化合物和抗氧化活性存在显著差异。由于其特有的化学异质性，自然生境导致了表征植物原材料质量的指标的多样性。在酚类化合物中，绿原酸和新绿原酸以及槲皮苷、芦丁和金丝桃苷被发现占主导地位。因此，这些化合物可被视为北欧叶片材料特有的植物化学标志物。
