The promoted marketing of these species in the market is hampered by their genetic variability and a lack of knowledge of techniques for reproduction, harvesting, and conservation. Therefore, active germplasm banks (AGBs) were created by The Brazilian Agricultural Research Corporation (EMBRAPA) to conserve genetic resources and optimize the use of these species. One of the approaches to the selection of species is metabolomics studies. In this work, using liquid chromatography‒mass spectrometry-based metabolomics, multivariate statistical analysis was used to correlate the metabolomic profiles of the bark, branches, and leaves of <em>S. mombin</em> and <em>S. tuberosa</em>. Thus, the compounds that most influenced the observed groups were identified and indicated as chemical markers of these species. To carry out the dereplication of the metabolomic profiles, a library of chemical structures of the Anacardiaceae family was constructed, which enabled the identification of 40 compounds, 10 of which were at level 1 using the library and reference standards and 30 at level 2 using only the library. The results of the present study showed that the branches and bark contain gallic acid and citric acid as chemical markers, and their profiles are similar between species. In the case of the leaves of <em>S. mombin</em>, the anacardic acid C17:3 and quercetin derivatives were identified as chemical markers, while the leaves of <em>S. tuberosa</em> contained the anacardic acids C17:1, C17:2, and C13 as chemical markers. Meteorological factors had a greater influence on the metabolic profile of the leaves than did genetic variability. In the case of <em>S. mombin</em> leaves, flavonoids are inversely correlated with cloudiness and directly correlated with the temperature at the collection site.</div></div>","PeriodicalId":8799,"journal":{"name":"Biochemical Systematics and Ecology","volume":"117 ","pages":"Article 104912"},"PeriodicalIF":1.4,"publicationDate":"2024-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142440912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Polyphenolic compounds were therefore profiled and quantified from pink peppercorns growing in 12 distinct locations in the Eastern and Western Cape provinces of South Africa using UPLC-QTOF-MS techniques. Eleven flavonoids were reported, including epigallocatechin gallate, +)-tephrorin B, astilbin, procyanidin B5, 4-benzyl-7-hydroxy-3-phenyl-2H-chromen-2-one, and isochamaejasmin which were reported for the first time in this species. Five phenolic acids, three glycosides, and tannins (theogallin (3-galloylquinic acid), digalloyl quinic acid, digalloylshikimic acid, β-glucogallin A and β-glucogallin B) were also revealed among others. PCA revealed a high composition of polyphenolic compounds in the Eastern in comparison to the Western Cape regions. Flavonoids were glaringly higher in winter rainfall receiving coastal regions. Consequently, the highest catechin content was 229% higher in the Eastern (1269.9 mg/kg) than the Western Cape (553.4 mg/kg). Furthermore, isochamaejasmin, the compound with possibly the highest concentration is reported in George (1741 mg/kg) and Gqeberha (2601.2 mg/kg) representing 149% differences between the two regions.
