Ecometabolomic studies can reveal detailed insights into the molecular functioning of these interactions, providing fundamental implications for conservation efforts. We assessed the chemical variation in <em>Centaurea kosaninii</em>, a plant species endemic to the Balkan Peninsula. Plant materials were collected from five wild-growing populations in Kosovo to investigate the genetic variability, chemical diversity, composition of the volatile organic compounds (VOCs), total phenolics content (TPC), total flavonoids content (TFC) and antioxidant activity. The nuclear and chloroplast loci were amplified and sequenced, showing minimal genetic diversity among the examined populations. VOCs were extracted using hydro-distillation and analyzed using gas chromatography, revealing the separation of 107 VOC constituents. Principal component analysis, principal coordinates analysis, discriminant analysis, and Boruta, based on random forest variable selection, demonstrated distinct chemical compositions of VOCs across different populations. Additionally, spectrophotometric methods were utilised to determine TPC, TFC, and antioxidant activities, revealing significant differences between the leaves and inflorescences of <em>C. kosaninii</em>. We also found strong correlations between TPC and TFC with DPPH radical scavenging activity, while the correlations with FRAP activity were more moderate. This study provides the first insights into the genetic and chemical diversity of <em>C. kosaninii</em>, contributing to scientific understanding and laying the groundwork for future research initiatives, focusing on its ecological roles, adaptive traits, population dynamics, conservation strategies and potential biotechnological applications.</div></div>","PeriodicalId":8799,"journal":{"name":"Biochemical Systematics and Ecology","volume":"122 ","pages":"Article 105037"},"PeriodicalIF":1.4,"publicationDate":"2025-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144229521","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}

However, there is a lack of region-specific data regarding its biomass and oil productivity. To address this gap, an experimental plantation was established in 2023 at the Forest College and Research Institute, Mulugu, Siddipet district, Telangana. The study aimed to identify the soil parameters influencing biomass yield, essential oil content, and citral concentration. The results showed that the annual biomass yield was approximately 6140 kg per hectare across three harvests, which is comparable to yields in other regions. Among the drying methods, shade drying for 36 h resulted in the highest oil yield (0.77–0.85 %), followed by oven drying at 45 °C for 7 h (0.71–0.78 %) and sun drying for 48 h (0.65–0.73 %). The citral concentration in the extracted oil ranged between 65 % and 84 %, depending on the harvest and drying technique. Statistical analysis revealed a positive correlation between soil nitrogen and phosphorus levels and biomass productivity, indicating that nutrient-rich soils enhance lemongrass growth.

We employed a comprehensive suite of analytical and biological assays to evaluate CCEO. The chemical composition was analyzed <em>via</em> GC-MS. Antioxidant properties were assessed through multiple complementary methods, including DPPH and ABTS radical scavenging, Ferric Reducing Antioxidant Power (FRAP), and Total Antioxidant Capacity (TAC) assays, with BHT as reference standard. Dermoprotective activity was evaluated through tyrosinase inhibition using the <span>l</span>-DOPA test, while anti-diabetic potential was measured <em>via</em> α-amylase inhibition using the DNSA method. The antibacterial activity was investigated through minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) determinations against both Gram-positive and Gram-negative bacterial strains, utilizing a broth microdilution method with resazurin as a growth indicator. The CCEO was found to contain 15 compounds, with the major constituents being geranial (43.02 %), neral (32.4 %), geraniol (4.7), and β-myrcene (4.3 %). The oil exhibited moderate antioxidant activity, with DPPH and ABTS radical scavenging IC₅₀ values of 106.2 ± 3.7 μg/mL and 98.3 ± 4.4 μg/mL, respectively. Its ferric reducing antioxidant power (FRAP) gave an EC₅₀ of 265.8 ± 3.5 μg/mL. The total antioxidant capacity was 495.7 ± 15.4 mg AAE/g EO. Interestingly, the CCEO demonstrated moderate inhibitory effects on key enzymes. It inhibited tyrosinase by 43.3 % at a concentration of 12.8 mg/mL and α-amylase by 24.8 % at a concentration of 11.1 mg/mL.
