Dracocephalum multicaule is a valuable medicinal and aromatic plant belonging to the Lamiaceae family. Its essential oils exhibit anticholinesterase, antioxidant, antimicrobial, anti-inflammatory, and neuroprotective activities, making them suitable for pharmaceutical and food industry applications. However, the optimal harvest time for maximizing essential oil yield and quality remains unclear. 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.

Essential oils (EO) are volatile plant substances that can be used in the development of natural herbicides, offering an alternative that is less harmful to the environment. This study investigated the phytotoxicity of Hesperozygis ringens essential oil and its major compound, pulegone, on Conyza bonariensis, an infesting plant, and Plantago australis, native species. H. ringens leaves were collected and the EO was extracted by hydro-distillation. The concentrations of 0, 0.001, 0.0025, 0.005, 0.01, and 0.02 % of the EO were tested in bioassays of both germination and early vegetative development, as well as 0, 1.0 % in adult plants. The experiments were conducted on Petri dishes and glass flasks, under controlled conditions. An analysis of variance (ANOVA) was used to evaluate the data. The EO contained 29 compounds, and pulegone was the major compound. 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. In adult plants, EO toxicity was observed starting at 24 h, reaching its maximum within 72 h. The results confirmed the toxic activity of the EO, indicating that H. ringens is a promising source for natural herbicides.

The constituents of the marine red alga Laurencia hamata Yamada (Kagi-sozo in Japanese), which was entangled in the brown alga Sargassum sp., collected from the coast of Oga Peninsula, Akita Prefecture, Japan were investigated. This species produced two halogenated C15-acetogenins, a new hamatenyne (2) and a known cis-maneonene-A (1). Their structures were deduced on the basis of spectroscopic data and comparison with previously reported data. In addition, the biological activities of the isolated compounds were evaluated against the brine shrimp assay and the DPPH antioxidant assay. This is the first report on chemistry and morphology of L. hamata.

Withania adpressa Coss. ex Batt., a medicinal species of the Solanaceae family, thrives in the Moroccan Sahara and Algeria. The purpose of this study was to determine the phytochemical constituents and assess the insecticidal, antifungal, and antioxidant properties of extracts obtained using different solvents. 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. Overall, these findings highlight W. adpressa as a promising source of bioactive compounds with strong antioxidant and biopesticidal properties. This supports its potential application in the development of eco-friendly pest management strategies and natural antioxidant agents.

The genus Ajuga L. (Lamiaceae), known for its diverse morphological traits and established medicinal properties, comprises over 300 species worldwide. Despite its pharmacological relevance, inter- and intraspecific metabolomic and chemodiversity data remain limited. This study employed a comprehensive, untargeted metabolomics approach that integrated FTIR and QTRAP LC–MS/MS with molecular networking to address this knowledge gap. Twenty-five accessions, representing two species, three subspecies, and two varieties, were collected from natural habitats. The dried aerial parts were extracted using 98 % methanol and then processed via ultrasonic homogenization. An automated workflow facilitated compound annotation, biomarker identification, intraspecific variation analysis, chemotype identification, and molecular networking using MetaboAnalyst 6.0 and the GNPS platform. FTIR profiling revealed dominant vibrational bands associated with O–H, N–H, C–H, CO, CC, C–O, and C–N stretching, as well as N–H and C–H bending. Classical molecular networking via the GNPS platform annotated 261 molecular features, including 139 metabolites that had not been previously reported in Ajuga. A total of 77 validated biomarkers and 17 intraspecific chemotypes with distinct taxonomic significance were identified. Sixty-nine molecular networks were constructed, displaying extensive subcluster diversity and rich chemical variability. The integrated analytical pipeline combining LC-MS/MS and FTIR fingerprinting with multivariate and automated workflows effectively discriminated Ajuga taxa. The chemodiversity uncovered in thi study provides essential data for future phytochemical and pharmacological investigations.

FTIR profiling revealed dominant vibrational bands associated with O–H, N–H, C–H, C<img>O, C<img>C, C–O, and C–N stretching, as well as N–H and C–H bending. Classical molecular networking via the GNPS platform annotated 261 molecular features, including 139 metabolites that had not been previously reported in <em>Ajuga.</em> A total of 77 validated biomarkers and 17 intraspecific chemotypes with distinct taxonomic significance were identified. Sixty-nine molecular networks were constructed, displaying extensive subcluster diversity and rich chemical variability. The integrated analytical pipeline combining LC-MS/MS and FTIR fingerprinting with multivariate and automated workflows effectively discriminated <em>Ajuga</em> taxa. The chemodiversity uncovered in thi study provides essential data for future phytochemical and pharmacological investigations.</div></div>","PeriodicalId":8799,"journal":{"name":"Biochemical Systematics and Ecology","volume":"126 ","pages":"Article 105232"},"PeriodicalIF":2.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146090470","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}

A phytochemical investigation of the ethanol extract of Callicarpa pedunculata R. Br. (Lamiaceae) led to the isolation and characterization of 20 compounds classified to terpenoids (1−11), flavonoids (12 and 13), lignans (14 and 15), and phenols (16−20). Their structures were identified based on extensive spectroscopic methods as well as comparison with the literature. Compounds 14−18 were newly isolated from the Lamiaceae family. Nine compounds 5, 10, 11, and 14−19 were firstly reported in the genus Callicarpa, and sixteen compounds 2−5 and 9−20 were identified from C. pedunculata for the first time. This work enriched the known chemical diversity of the secondary metabolites in the C. pedunculata.
