Seven phenolic compounds (ferulic acid, caffeic acid, 4‐methoxycinnamic acid, 3,4‐dimethoxycinnamic acid, 3‐hydroxy‐4‐methoxybenzaldehyde, 3‐methoxy‐4‐hydroxypropiophenone and 1‐O,2‐O‐digalloyl‐6‐O‐trans‐p‐coumaroyl‐β‐D‐glucopyranoside), a flavanonol (7‐O‐methylaromadendrin), two lignans (pinoresinol and matairesinol) and six diterpenic acids/alcohol (19‐acetoxy‐13‐hydroxyabda‐8(17),14‐diene, totarol, 7‐oxodehydroabietic acid, dehydroabietic acid, communic acid and isopimaric acid) were isolated from the hydroalcoholic extract of a Brazilian Brown Propolis and characterized by NMR spectral data analysis. The volatile fraction of brown propolis was characterized by CG‐MS, composed mainly of monoterpenes and sesquiterpenes, being the major α‐pinene (18.4 %) and β‐pinene (10.3 %). This propolis chemical profile indicates that Pinus spp., Eucalyptus spp. and Araucaria angustifolia might be its primary plants source. The brown propolis displayed significant activity against Plasmodium falciparum D6 and W2 strains with IC50 of 5.3 and 9.7 μg/mL, respectively. The volatile fraction was also active with IC50 of 22.5 and 41.8 μg/mL, respectively. Among the compounds, 1‐O,2‐O‐digalloyl‐6‐O‐trans‐p‐coumaroyl‐β‐D‐glucopyranoside showed IC50 of 3.1 and 1.0 μg/mL against D6 and W2 strains, respectively, while communic acid showed an IC50 of 4.0 μg/mL against W2 strain. Cytotoxicity was determined on four tumor cell lines (SK‐MEL, KB, BT‐549, and SK‐OV‐3) and two normal renal cell lines (LLC‐PK1 and VERO). Matairesinol, 7‐O‐methylaromadendrin, and isopimaric acid showed an IC50 range of 1.8–0.78 μg/mL, 7.3–100 μg/mL, and 17–18 μg/mL, respectively, against the tumor cell lines but they were not cytotoxic against normal cell lines. The crude extract of brown propolis displayed antimicrobial activity against C. neoformans, methicillin‐resistant Staphylococcus aureus, and P. aeruginosa at 29.9 μg/mL, 178.9 μg/mL, and 160.7 μg/mL, respectively. The volatile fraction inhibited the growth of C. neoformans at 53.0 μg/mL. The compounds 3‐hydroxy‐4‐methoxybenzaldehyde, 3‐methoxy‐4‐hydroxypropiophenone and 7‐oxodehydroabietic acid were active against C. neoformans, and caffeic and communic acids were active against methicillin‐resistant Staphylococcus aureus.

“…Previous studies of EO effects in A. obtectus have involved EOs isolated from plants belonging to families of Amaranthaceae [58], Asteraceae [59], Cupressaceae [60], Lamiaceae [61][62][63], Lauraceae [64], Meliaceae [65], Myrtaceae [60,62,64,66], Piperaceae [65], Poaceae [67], Rutaceae [68]. In the present study we examined how thyme EO (Thymus vulgaris L., Lamiaceae, thymol chemotype) applied by contact affected A. obtectus mortality, F1 progeny production and choice of seeds for oviposition.…”

The bean weevil Acanthoscelides obtectus Say (Coleoptera: Chrysomelidae: Bruchinae) can cause significant losses in production of its primary host common bean Phaseolus vulgaris L. To avoid bean protection with environmentally risky chemical insecticides and provide sustainable and safe production of food, new pest management methods based on natural compounds are investigated. In the present study, we evaluated protective potential of the essential oil (EO) from the common thyme Thymus vulgaris L. applied on bean seeds. We assessed residual contact toxicity of thyme EO and its effects on A. obtectus longevity, oviposition and adult emergence. Furthermore, to elucidate the role of oxidative stress in thyme EO toxicity, we estimated the levels of oxidatively damaged proteins and lipids, as well as the level of thiols which have important role for antioxidant capacity. We found that thyme oil significantly reduced adult survival and longevity, induced oxidative damage to lipids and proteins and depleted protein and non-protein thiols in a concentration-dependent manner. Females appeared to be more tolerant to thyme oil treatment than males. Sublethal EO concentrations affected oxidative stress indices, deterred oviposition and strongly inhibited adult emergence. The results suggest that thyme oil has the potential to be used as an ecofriendly insecticide for A. obtectus control.

“…However, the amount concentrations of components vary from one region to another due to the influence of many factors, including harvest season, climate, soil type, age of the plants and the extraction . For example, Bett et al [58] reported the dominance of oxygenated monoterpenes in the leaf EOs of C. lusitanica growing in Kenya with umbellulone (18.38%), αpinene (9.97%), sabinene (8.16%) and limonene (7.91%) as major compounds. Almost similar results were reported by Kuiate et al [20] for leaves in Cameroon with dominance of umbellulone (18.30%), pinene (7.40%), epizonarene (5.0%), limonene (3.5%) and terpinenol (2.6%).…”

Chemical composition and essential oil contents among essential oil-bearing plants are mostly influenced by different factors including ecological features of habitat. In this study, variation in yield and chemical composition of essential oils (EOs) from the leaves of Cupressus lusitanica Mill. (Cupressaceae) in different regions of Rwanda was investigated. Extraction of essential oils from fresh leaves of C. lusitanica collected in March 2021 and April, 2021 from three different ecological zones of Rwanda, Buberuka highland zone (Burera), Central plateau zone (Huye) and Eastern savannah zone (Kayonza) was realized through steam distillation. The chemical compositions of distilled EOs were analyzed using both Fourier transform infrared (FT-IR) spectroscopy and gas chromatography-mass spectrometry (GC-MS), while their yields were determined by simple calculus. The average yields of the EOs were 0.27 ± 0.02, 0.34 ± 0.02 and 0.39 ± 0.01% (v/w) for Burera, Huye and Kayonza, respectively. Results of FT-IR analysis were confirmed by those of GC-MS analysis, and indicated the presence of different groups of compounds including aliphatic alkanes, carboxylic acids, alkenes, aldehydes, aromatics and ketones in the EOs. GC-MS results revealed that sabinene (20.84%), myrcene (19.63%), α-pinene (10.23%) and δ-3-carene (10.13%) were the dominant chemical constituents for EOs of C. lusitanica from Burera. Umbellulone (24.21%), δ-3-carene (16.76%), sabinene (10.54%) and α-pinene (8.21%) were the main constituents for EOs of C. lusitanica from Huye, while γ-terpinene (18.77%), umbellulone (18.16%), isobornyl acetate (9.972%), and myrcene (7.20%) were the major components of EOs of C. lusitanica from Kayonza. The current results demonstrated an intraspecific variation in content and chemical profile of C. lusitanica EOs from one geographical region to another. The observed variations are mostly due to the interactions of C. lusitanica species with climatic and environmental conditions of ecological habitat. However, it could also be the effects of various biotic factors, as well as maturity of plant and stage of plant growth. Further studies are needed to establish the influence of different geo-climatic and environmental factors on each single major component of C. lusitanica EOs.
