“…In addition, of the selected components, only β-caryophyllene showed strong contact toxicity when applied topically, while none of the other compounds possessed topical, residual, or fumigant toxicity against bed bugs. In the past, researchers have reported [18] that β-caryophyllene, β-pinene [25,26], caryophyllene oxide, and α-humulene have contact, fumigant, and residual toxicity against various pests of stored grains, crops, and vector-borne diseases. However, only β-caryophyllene induced toxicity in adult bed bugs.…”

Kadsura coccinea (Lem.) A.C. Smith is an evergreen, woody climbing plant that is widely distributed throughout southwest mainland China. Extracts of this plant are used in traditional Chinese medicine (TCM) for the treatment of various diseases, like cancer and dermatosis, and as an anodyne to relieve pain, while the leaves are used to treat eczema. In the current study, the toxicity of essential oil from its stem (EOKC) was studied against two strains of bed bugs (Cimex lectularius). Essential oil from the plant was obtained by hydrodistillation and analyzed by GC/MS. The major compound identified was β-caryophyllene (24.73%), followed by caryophyllene oxide (5.91%), α-humulene (3.48%), and β-pinene (2.54%). Preliminary screening was performed by topically delivering a 1 µL droplet of the treatments dissolved in acetone. At 24 h after treatment, the EOKC induced mortality rates of 61.9% and 66.7% in the Bayonne and Ft. Dix strains, respectively, at 100 µg/bug. Four major compounds—β-caryophyllene, caryophyllene oxide, α-humulene, and β-pinene—were selected based on their availability and were subjected to topical, residual, and fumigation methods. When applied topically, only β-caryophyllene induced high toxicity in both strains. None of the selected compounds induced significant toxicity in the residual and fumigation methods.

“…Analysis of the data obtained showed that the age of the respondents varied between 22 and 80 years, with a majority of the age group [41][42][43][44][45][46][47][48][49][50] at 34%. Then come the age groups [51][52][53][54][55][56][57][58][59][60], [31][32][33][34][35][36][37][38][39][40], [21][22][23][24][25][26][27][28][29][30] and finally those over 61, with a rate of 26%, 18.7%, 11.3% and 10% respectively. On the one hand, this could be explained by the ignorance of the traditional medicinal uses of plants by the younger generation.…”

The use of plants to treat chronic diseases is part of an ancient Moroccan tradition. This study will present the first relevant documentation on medicinal plants used in the treatment of hypertension in Tarfaya province. This study aimed to collect and document information on medicinal plants traditionally used by the local population of Tarfaya province for the treatment of hypertension. Ethnobotanical surveys were conducted using 150 questionnaires in the study area. Documented data were evaluated using the quantitative ethno-botanical indices of frequency citation (FC) and Relative Frequency of Citation (RFC). The results obtained allowed to inventory 52 species of medicinal plants belonging to 29 families traditionally used against hypertension. The species were rich in diverse chemical constituents. The most cited families are Lamiaceae (9 species), Apiaceae (5 species), Compositae (3 species), Leguminosae (3 species) and Myrtaceae (3 species). Ten plants are reported for the first time as used in the treatment of hypertension. The most cited plant species are Allium sativum (RFC = 0.28), Allium cepa (RFC = 0.2), Olea europaea (RFC = 0.18), Searsia tripartita (RFC = 0.16), Ammodaucus leucotrichus (RFC = 0.15) and Myrtus communis (RFC = 0.15). Leaves were the most used organs. The decoction was the dominant method of preparation. This study showed that the inhabitants of Tarfaya use a wide variety of plants for the treatment of hypertension. This work is a source of information that can serve as a basis for phytochemists and pharmacologists interested in research on plants with antihypertensive effect.

“…Aromadendrene was documented to be active against Gram(+) and Gram(−) bacteria and yeast [30] . In addition, this compound was known to possess insecticidal properties, [31] as well as bicyclogermacrene [32] and ledene, [33] acting in particular as larvicidal. Bornyl acetate, detected even in the essential oils of Rosmarinus officinalis [34] and Juniperus horizontalis , [35] was recognized as acaricidal [36] .…”

Lodoicea maldivica (J.F.Gmel.) Pers. (Arecaceae), 'Coco de Mer', is a palm, growing as endemic in the Seychelles islands. Its fruit weighs up to 20 kg and is characterized by a fleshy and fibrous envelope surrounding the nutlike portion. The present work combines a morpho-anatomical and a phytochemical analysis of the fruit exocarp and mesocarp. The exocarp is composed by a layer of palisade cells. The mesocarp is characterized by vascular bundles and by sclereids. In the aerenchyma, the internal zone of the mesocarp, cells aggregates were positive to phenols, while idioblasts were positive to terpenes. We performed a GC/MS analysis with a semi-quantitative relative amount calculation of the recorded compounds. The GC/MS essential oil profile revealed the dominance of acyclic sesquiterpenoids (53.95 %), followed by bicyclic sesquiterpenoids (31.69 %), monoterpenes (11.89 %) and monocyclic sesquiterpenoids (2.44 %). The terpenes detected in higher amounts, β-caryophyllene and bicyclogermacrene, are known for activity against insect larvae, but have been proposed as antiviral candidates against SARS-CoV-2. The third compound in amount, aromadendrene, is active against bacteria and, again, known to possess insecticidal properties.
