Orange peel, a rich of polyphenols and flavonoids, offers significant potential for sustainable application. This research formulated a novel multi-task optimization approach combining the Mantis Search Algorithm (MSA) with hybrid machine learning models to extract bioactive compounds from orange peel waste using natural deep eutectic solvents (NADES) and microwave-assisted extraction (MAE). The holistic strategy employed a multi-task optimization approach that concurrently optimized four key components: feature selection, model hyperparameters, ensemble weights, and process parameters. The process parameters investigated included microwave power (302–495 W), extraction temperature (31–59 °C), extraction time (5.2–30 min), and mass-to-solvent ratio (41–80 mg/mL). Three machine learning models were developed and systematically compared: CatBoost, Group Method of Data Handling (GMDH), and their weighted ensemble fusion. The ensemble MSA-hybrid model exhibited the best predictive performance with R² of 0.656, 0.981, and 0.990 for total phenolic content, total flavonoid content, and DPPH radical scavenging activity, respectively. Temperature was found to be the most significant process parameter for all response variables, followed by extraction time and mass-to-solvent ratio. The multi-task optimization approach successfully developed robust predictive models capable of guiding extraction parameter selection for improved bioactive compound yields. Extensive validation using thorough residual analysis, stability testing, and confidence interval analysis reaffirmed model reliability and generalizability. This novel study was successful in offering valuable industry-ready solutions for sustainable bioactive compound extraction while supporting agricultural waste valorization and circular economy concepts.</div></div>","PeriodicalId":15136,"journal":{"name":"Journal of Applied Research on Medicinal and Aromatic Plants","volume":"49 ","pages":"Article 100668"},"PeriodicalIF":3.6,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145270310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study measured 12 phenotypic traits of seeds and pods in 180 individual trees from 17 natural <em>G. sinensis</em> populations in Guizhou Province and detected rich phenotypic diversity. The results suggest that the phenotypic variation of <em>G. sinensis</em> seeds and pods in Guizhou is extremely rich, with intrapopulation variation being the primary source of variation. The average phenotypic differentiation coefficient is 23.87 %, and the average coefficient of variation is 11.59 %. The variation in phenotypic traits of <em>G. sinensis</em> seeds and pods is geographically discontinuous. Generally, pods show north-south variation along the same longitude, while seeds exhibit east-west variation along the same latitude. Inter-population variability in pods (14.67 %) is higher than in seeds (8.96 %), suggesting greater variability in pod traits and higher stability in seed traits. This multi-level variation provides a scientific basis for the innovative utilization of high-quality genetic resources of <em>G. sinensis</em>. Principal component analysis shows that the first three principal components (size of pods, size and weight of seeds, weight of pods) account for 81.9 % of the cumulative contribution, essentially reflecting most of the information on phenotypic traits of <em>G. sinensis</em>. A comprehensive evaluation of the natural populations of <em>G. sinensis</em> based on 12 pods and seeds traits finds that the CeHeng (CH) population has the best overall performance, followed by WangMo (WM), DeJiang (DJ), and Weng'an (WA) populations. Suitable breeding materials can be selected from these four populations based on breeding objectives.

This study investigated their collective impact on secondary metabolite composition and aroma characteristics in fresh tea leaves, aiming to identify key biochemical markers and optimize cultivation. Utilizing GC-MS metabolomics, fresh leaves from young and old tea plants across varying altitudes (200–800 m) in Wuyishan were analyzed. Soil physicochemical properties were also assessed, with multivariate statistics employed for metabolic profiling. Results showed young tea plants possessed higher volatile terpenoids, aromatic alcohols (e.g., benzyl alcohol, linalool oxides), and alkaloids (e.g., caffeine), contributing to floral-green aromas. Conversely, old tea plants accumulated saturated fatty acids and antioxidant phenolics (e.g., sesamol), yielding fruity-woody notes. Altitudinal effects were age-dependent; high elevations boosted stress-protective volatiles (e.g., trans-furan linalool oxide) in young plants, while old plants exhibited metabolic stability. Soil pH, organic matter, and nutrients (N, P) significantly correlated with aroma profiles (<em>P</em> &lt; 0.05), with lower pH favoring fruity esters and higher nutrients promoting fatty aromas. This metabolic shift from defense-oriented volatiles in young plants to structural/antioxidant compounds in mature plants reflects ontogenetic resource allocation. Altitude-induced stress responses were pronounced in younger, more plastic plants. Soil properties modulate aroma pathways, likely via microbial and enzymatic interactions. These findings align with ecological trade-off and stress-induced secondary metabolism theories. In conclusion, tea quality is dynamically regulated by plant age, altitude, and soil factors. Young tea leaves are optimal for floral-green aromas, while older leaves offer antioxidant-rich profiles. Altitude-specific cultivation and soil management (e.g., pH adjustment, organic matter enrichment) can precisely target desired aroma traits, bridging ecological theory with agricultural practice for enhanced tea quality and bioactive properties.</div></div>","PeriodicalId":15136,"journal":{"name":"Journal of Applied Research on Medicinal and Aromatic Plants","volume":"49 ","pages":"Article 100674"},"PeriodicalIF":3.6,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145359254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
