This study aimed to evaluate variations in essential oil content and composition of D. multicaule at different phenological stages to determine the most suitable harvest period. Plant samples were collected in 2023 at eight distinct phenological stages, ranging from vegetative growth to the ripe seed stage. Essential oils were extracted by hydrodistillation using a Clevenger-type apparatus and analyzed by gas chromatography-mass spectrometry (GC-MS). Essential oil content varied significantly across phenological stages, ranging from 0.50 % to 0.72 % (w/w). The highest essential oil content (0.72 % w/w) was observed at the 75 % flowering stage, with no statistically significant differences compared to the 50 % flowering (0.69 %) and full flowering (0.62 %) stages. Seven major compounds were identified, accounting for 96.10 %–99.16 % of the total essential oil composition. The predominant constituents were perilla aldehyde (40.03–65.29 %), limonene (23.06–37.65 %), α-pinene (2.28–5.08 %), and carvone (1.10–20.79 %). Perilla aldehyde reached its maximum concentration (65.29 %) at the 75 % flowering stage, whereas limonene was highest at the ripe seed stage. Considering both essential oil yield and chemical composition, the 75 % flowering stage was identified as the optimal harvest time for D. multicaule, providing superior oil content and a favorable phytochemical profile for pharmaceutical and industrial uses.</div></div>","PeriodicalId":8799,"journal":{"name":"Biochemical Systematics and Ecology","volume":"126 ","pages":"Article 105215"},"PeriodicalIF":2.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145939810","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}

The concentrations of 0.01 and 0.02 % inhibited germination and affected early development, causing damages to the membranes, especially in C. bonariensis. Pulegone also had toxicity, yet less intense than the EO, thus suggesting that the synergy of compounds is responsible for the toxic activity.

Three solvents with varying polarities (methanol, ethyl acetate, and dichloromethane) were employed for extraction. The methanolic extract exhibited the highest contents of total phenolics (65.19 mg GAE/g extract) and flavonoids (9.38 mg QE/g extract). These compounds were strongly associated with potent antioxidant activities, as confirmed by DPPH (IC50 = 0.029 mg/mL), FRAP (EC50 = 0.007 mg/mL), and total antioxidant capacity assays (335.39 mg AAE/g extract). In contrast, the dichloromethane extract showed only moderate antifungal activity against Penicillium expansum, with minimum inhibitory concentrations (MIC) ≥ 5 mg/mL. Insecticidal bioassays against adults of Tribolium castaneum revealed that the ethyl acetate extract was the most toxic, with an LD50 value of 1.91 mg/cm2.

Using quantitative 1H NMR (qNMR), fifteen volatile constituents including 1,8-cineole, β-pinene, α-pinene, limonene, and β-eudesmol were quantified, revealing significant influences of leaf maturity, drying method, and seasonal variation on EO yield and composition. Among the three Eucalyptus species studied (E. tereticornis, E. citriodora, and E. camaldulensis), E. tereticornis exhibited the most diverse and abundant volatile profile. Biological evaluation in N2a neuroblastoma cells under LPS-induced inflammatory stress demonstrated that select EOs and terpenoids particularly myrtenal significantly promoted neurite outgrowth and cell viability.
