“…Under specific environmental conditions, the uptake and accumulation of elements from the soil are affected. As a response to water stress, plants accumulate some elements in the roots that will be translocated later to satisfy their needs [ 63 , 64 ]. Furthermore, genetic determinism has been demonstrated to affect the accumulation of elements by the olive tree.…”

The aim of this study was to investigate the levels of trace elements in olive oils from different locations and their use for geographical authentication. Concentrations of seventeen elements were determined in a total of 42 olive oils from Tunisia, Spain (Basque country), and southern France, and in nine soil samples from Tunisia by quadrupole inductively plasma mass spectrometry. The compilation of appropriate techniques integrated into the analytical procedure achieved a precision (RSD) between 2% and 15% and low limits of detection (between 0.0002 and 0.313 µg kg−1). The accuracy of the analytical method applied for olive oil analysis was evaluated using SRM NIST 2387 Peanut butter. The recoveries obtained after microwave-assisted digestion for the certified elements ranged between 86% and 102%. Concentrations of non-certified elements (V, Cr, Co, Ni, Ba, Rb, Sr, Cd, Pb, and As) were presented. The use of Pearson correlation applied on paired Tunisian oil/soil samples has shown that several elements (Mg, Mn, Ni, and Sr) were significantly correlated. The multivariate statistics using principal component analysis have successfully discriminated against three studied origins. The most significant variables were the elemental concentrations of Cu, Cr, Fe, Mn, Sr, V, and Zn. This study shows the potential of applying trace elements profiles for olive oil geographical discrimination.

“…The adaptation of a cultivar to a novel environment is strongly linked to the nutrient uptake capacity [31]. Olive tree is considered a species with a great capacity to survive and produce in low fertility soils [32] and under harsh climatic conditions [33]. In fact, drought stress affects uptake, transport, and following allocation In this study our approach was to follow the evolution of the mineral elements (N, P, K, Na and Ca) of the olive tree Meski according to the climatic change, as well as the distribution and the dynamics of these elements in their various organs, leaves, wood and roots.…”

“…Nitrogen was transported to flower and fruits, and thus lower leaf N content was observed. Since, azote is essential for regulating the plant response to environmental changes and adaptation of photosynthesis to water stress [32][33][34][35][36][37][38].…”

“…Persentase area puncak tertinggi kedua pada ekstrak daun muda abiu yaitu senyawa bioaktif 18,18'-Bi-1,4,7,10,13,16-Heksa oksa siklo nonadekana (Tabel 1), senyawa tersebut merupakan golongan hidrokarbon (Vivek et al, 2009). Senyawa hidrokarbon berupa heksadekana, heptadekana dan oktadekana merupakan salah satu senyawa indikator terhadap stres kekeringan (Mansour-Gueddes et al, 2018). Senyawa 2-metil benzaldehida juga terdapat dalam ekstrak daun muda abiu, senyawa tersebut berperan sebagai anti tungau (Yang et al, 2014).…”

Abiu (Pouteria caimito) merupakan tanaman tropis eksotis yang mempunyai banyak manfaat untuk kesehatan. Abiu merupakan tanaman yang menarik karena kandungan senyawa bioaktifnya yang beragam sehingga perlu untuk dilakukan penelitian terhadap berbagai senyawa bioaktif yang terkandung pada masing-masing bagian tanaman abiu. Tujuan dari penelitian ini adalah untuk mengidentifikasi dan mengevaluasi kandungan senyawa bioaktif dari ekstrak beberapa bagian tanaman abiu serta manfaatnya. Penelitian ini menggunakan lima (5) bagian tanaman abiu yaitu daun muda, daun dewasa, buah mentah, daging buah matang dan kulit buah matang. Percobaan dilakukan dalam rancangan acak lengkap (RAL) dengan lima ulangan. Analisa kandungan senyawa bioaktif abiu menggunakan alat gas chromatography mass spectrometry (GCMS). Hasil penelitian menunjukkan bahwa seluruh bagian tanaman abiu mengandung senyawa bioaktif yang bermanfaat untuk kesehatan, khususnya sebagai anti kanker. Senyawa-senyawa tersebut antara lain: 1-(2-Hidroksietil)-1,2,4-triazole, 5-hidroksi metil furfural, 1-metil-5-fluorourasil dan trans-geranilgeraniol. Senyawa 1-(2-Hidroksietil)-1,2,4-triazole terkandung di dalam daun muda dan daun dewasa abiu. Senyawa 5-hidroksi metil furfural terkandung di dalam buah abiu mentah, daging buah abiu matang dan kulit buah abiu matang. Senyawa 1-metil-5-fluorourasil ditemukan di dalam daging buah abiu matang. Senyawa trans-geranilgeraniol ditemukan di dalam daging buah abiu matang dan kulit buah abiu matang. Kata kunci: Anti-kanker, antioksidan, ekstrak, GCMS, kesehatan.
