GC-MS analysis of EOL revealed thirty-eight components dominated by <em>β</em>-cadinene (21.27%). Meanwhile, for EOF, it showed thirty-seven components dominated by <em>α</em>-pinene (12.72%).

This study investigates a synergistic approach using a matrix of plant-derived samples to address this limitation and enhance their repellency. In olfactory studies, powdered samples and extracts—both individual and blended—were tested against <em>Anopheles gambiae</em> s.l. and <em>Anopheles funestus</em> in laboratory and semi-field environments. Euclidean distances, Hierarchical clustering, and heatmap analyses assessed compound relationships to repellent compounds that were literature-cited. Molecular fingerprints from SMILES identifiers and Tanimoto coefficients quantified structural similarity.

This species has applications in traditional medicine, pharmaceuticals, and cosmetics due to its high content of phenolic compounds, such as anthocyanins and tannins in its fruits, which have antioxidant and anti-inflammatory properties. This work aims to evaluate the influence of seasonality on chemical composition, and in vitro cytotoxicity and anti-inflammatory activities of <em>M. dubia</em> essential oil. Botanical material was collected monthly, the leaf essential oils were extracted by hydrodistillation, and the fruits were subjected to simultaneous distillation-extraction. GC and GC-MS performed chemical analyses of the essential oils and volatile concentrates. The local climatic parameters insolation, temperature, relative humidity, and precipitation were monitored. The MTT assay was performed to evaluate cell viability. Subsequently, a nitrite standard curve was performed to determine the nitrite concentration in the samples. The oils were tested for cytotoxic activity against gastric ascites (AGP01), glioblastoma (AHOL), and lung cancer (A549) cell lines, as well as against non-malignant murine macrophages (RAW 264.7). The essential oil yield ranged from 0.4% (April/2024) to 0.9% (October/2023), with an annual average of 0.7 ± 0.1%. There were no significant differences in the yields of the dry and rainy periods. The leaf essential oils constituents were characterized by α-pinene (0.28–49.13%), (<em>E</em>)-caryophyllene (12.1–34.31%), caryophyllene oxide (4.03–17.08%), leptospermone (3.88–7.92%), and δ-cadinene (1.78–6.67%). The main compounds of fruit volatile concentrates were α-pinene (25.1–55.5%), α-terpineol (7.88–21.08%), limonene (6.43–16.79%), and (<em>E</em>)-caryophyllene (3.44–8.67%). The essential oils treatment of <em>M. dubia</em> seasonal study showed significant variations in the nitrite concentration, highlighting the oil's anti-inflammatory effect.

Nineteen of the 44 southern African taxa were screened, including eleven from <em>Senegalia</em> and eight from <em>Vachellia</em>. Lipophilic amine-specific extracts were produced from leaves, including other organs if available, then the extracts were studied by high performance liquid chromatography. The identities of four compounds were determined by nuclear magnetic resonance spectroscopy, i.e., tryptamine, <em>N</em>-methyltryptamine (NMT), <em>N,N</em>-dimethyltryptamine (DMT) and hordenine. With repeated sampling of select species (<em>Senegalia ataxacantha</em> (DC.) Kyal. &amp; Boatwr., <em>Senegalia caffra</em> (Thunb.) P.J.H.Hurter &amp; Mabb., and <em>Senegalia polyacantha</em> (Willd.)
