摘要/Abstract

摘要： 本研究基于“土壤-植物系统”视角，探究广东新会、恩平、博罗及广西浦北4 个产区陈皮矿质元素的分布、富集与传递规律，筛选具有成因依据的陈皮产地判别关键元素指标。通过同步采集上述产区土壤及陈皮根、叶和不同成熟期果皮（青皮、二红皮、大红皮）样品，测定36 种矿质元素含量，结合富集系数与主成分分析（principal component analysis，PCA）进行系统解析。结果表明，土壤中B、La、Ce、Pr、Nd、Sm等元素在新会产区含量显著高于其他产区（P＜0.05）；在陈皮叶片和不同时期果皮中，新会产区对Co、Cu、V的富集能力均为最强。PCA结果进一步揭示，博罗产区土壤-植物系统中稀土元素（Y、Er、Ho、Dy等）持续富集，构成其产地判别的重要依据。研究还发现，青皮与土壤元素相关性最强，是产地溯源的敏感材料；而随着果实成熟，元素分布趋于稳定，根据K、P、Ca等大量元素的分布模式可有效溯源新会、恩平及浦北产区。本研究不仅验证了矿质元素在陈皮产地鉴别中的可行性，更通过元素迁移累积路径揭示了判别指标的成因机制，可为构建稳健的陈皮产地溯源体系提供理论基础与科学依据。

Abstract: This study investigated the distribution, enrichment, and transfer patterns of mineral elements in the soil-plant system of dried tangerine peel (Citrus reticulata ‘Chachi’, or Chenpi) from four production regions: Xinhui, Enping and Boluo in Guangdong Province, and Pubei in Guangxi Province, aiming to identify key element indicators with causal basis for geographical origin discrimination. Citrus reticulata ‘Chachi’ root, surrounding soil, leaf, and peel samples at different maturity stages (green, semi-ripe, and fully ripe) were collected simultaneously from these regions. The contents of 36 mineral elements were determined and systematically analyzed using enrichment factors and principal component analysis (PCA). The results showed that the contents of elements such as B, La, Ce, Pr, Nd, and Sm were significantly higher in the soil sample from Xinhui than in those from the other regions (P < 0.05). Among the four production regions, the leaf and peel samples from Xinhui exhibited the strongest enrichment capacity for Cu, Co, and V. The PCA results revealed the continuous enrichment of rare earth elements (Y, Er, Ho, Dy, etc.) in the soil-plant system of the Boluo region, constituting a key basis for the geographical origin discrimination of Chenpi. This study also found that green peels had the strongest correlation with soil elements, establishing them as sensitive materials for the geographical origin tracing of Chenpi. As fruit maturity increased, the elemental distribution stabilized, and the distribution patterns of macro elements such as K, P, and Ca could effectively discriminate among Xinhui, Enping, and Pubei Chenpi. This study has not only verified the feasibility of using mineral element fingerprinting for the geographical origin discrimination of dried tangerine peel, but has also elucidated the formation mechanism of discriminant indicators from the perspective of elemental migration and accumulation pathways, providing a theoretical basis and scientific evidence for constructing a robust geographical origin traceability system for dried tangerine peel.

Key words: dried tangerine peel; Citrus reticulata ‘Chachi’; mineral element; bioconcentration factor; geographical origin traceability; soil
