“…Regarding the mode of action, several mechanisms through which essential oils produce neurotoxic effects have been proposed, such as EOs acting on GABA receptors, octopamine receptors, or acetylcholinesterase [30]. Further, the synergistic effect of the essential oil constituents likely increases their larvicidal activity [31][32][33]. Scalerandi et al proposed an interesting mode for synergistic effects using the metabolic model [34].…”

The larvicidal activity of essential oils (EOs) extracted from Cymbopogon citratus, Cymbopogon winterianus, Eucalyptus citriodora, and Eucalyptus camaldulensis aromatic plants grown in Vietnam was evaluated on Aedes aegypti larvae. The EOs were hydro-distilled in a Clevenger-type apparatus. The EOs were analyzed by gas chromatography-mass spectrometry (GC-MS). The mortality rates obtained from the bioassays were used to calculate the lethal concentrations (LC 50 ) of the EOs by the probit analysis method. These essential oils exhibited toxicity to the larvae of Aedes aegypti. Results were obtained for Cymbopogon citratus (LC 50 = 120.6 ppm), Cymbopogon winterianus (LC 50 = 38.8 ppm), Eucalyptus citriodora (LC 50 = 104.4 ppm), and Eucalyptus camaldulensis (LC 50 = 33.7 ppm). The essential oils of Eucalyptus camaldulensis and Cymbopogon winterianus were found to be the most efficient, and their respective values of LC 50 were 33.7 ppm, 38.8 ppm. In conclusion, this research adds to the growing body of literature on natural larvicides from essential oils against Aedes aegypti mosquitoes.

BACKGROUND: Dengue fever is caused by the spread of dengue virus by Aedes mosquito vectors. Currently, the most effective way to control dengue is by preventing mosquitoes from spreading the disease. Arisaema fargesii is a Chinese herbal medicine commonly used to repel mosquitoes. In our laboratory, anti-mosquito chemical components were extracted from A. fargesii, and the effects of these substances on mosquito larvae were examined. RESULTS: In total, 48 compounds corresponding to 98.79% of the total oil were identified and the major compounds identified were linalool (12.38%), carvacrol (8.27%), eugenol (5.21%), and -selinene (5.36%). Essential oil had larvicidal activity against Ae. aegypti and Ae. albopictus with LC 50 values of 40.49 mg/L, 47.01 mg/L, respectively. The LC 50 values of carvacrol, eugenol, linalool and -selinene were 32.78, 56.34, 70.56, 136.03 mg/L against Ae. aegypti larvae, and 39.08, 52.07, 82.34, 151.74 mg/L, respectively, against Ae. albopictus larvae. Biochemical assays of Aedes larvae showed that the activities of acetylcholinesterase (AChE), monooxygenases (MO), glutathione-S-transferase (GST), p-Nitrophenyl acetate (p-NPA) esterase, -esterase and -esterase were significantly affected by carvacrol. Essential oil induced the detoxification mechanism for the action of GST and MO.CONCLUSION: The result indicates that essential oil of A. fargesii and its isolated constituent have good inhibitory effects on the defense enzymes of Aedes mosquito larvae. A. fargesii essential oil can be used to control Aedes mosquito larvae to prevent the spread of dengue fever. /journal/ps a Retention index relative to n-alkanes on HP-5 MS capillary column. b Relative area (peak area relative to the total peak area). c RI, retention index, MS, mass spectrum, Co, co-injection with authentic compound.

“…Many plant species have pharmacological activities attributable to their phytoconstituents, for instance, glycosides, saponins, flavonoids, steroids, tannins, alkaloids and terpenes (Batiha et al, 2020). CEO includes many components such as flavonoids, alkaloids and monoterpenes, and has broad pharmacological efficacy (Osanloo, Sedaghat, Esmaeili, & Amani, 2018; Salim, 2017). Furthermore, the pharmacological effects of mentioned constituents are different, for example, the main site action of flavonoids is acetylcholinesterase (Perumalsamy, Jang, Kim, Kadarkarai, & Ahn, 2015), as well as alkaloids and monoterpenes target Na‐K‐ATPase or Na + and K + channels (Lucia, Zerba, & Masuh, 2013; Rajashekar & Shivanandappa, 2017).…”

The beneficial effect of clove essential oil and its major component, eugenol, on erectile function in diabetic rats

et al. 2020

Diabetic men are at a higher risk of erectile dysfunction (ED). A tropical plant, clove (Syn. Eugenia caryophyllata, Caryophyllus aromaticus L., Syzygium aromaticum (L.) Merr. & L.M. Perry) from the Myrtaceae family has displayed aphrodisiac activity. The present research aimed to investigate the impacts of clove essential oil (CEO) and the ingredient of CEO, eugenol (E) on ED in diabetic rats. We divided Sprague‐Dawley rats into control and diabetic groups. Erectile function was evaluated before and after CEO and E intracavernosal injection. CEO‐ and E‐induced relaxation responses were investigated in isolated corpus cavernosum (CC) using various inhibitors. The intracavernous administration of CEO and E restored erectile responses in diabetic rats. CEO and E induced remarkable relaxation in all groups. CEO‐ and E‐induced relaxation responses were partially inhibited after pre‐contraction with KCl. Tetraethylammonium and glibenclamide inhibited the relaxation response to CEO. Glibenclamide inhibited maximum relaxation to E. The inhibitors of nitric oxide synthase (NOS), soluble guanylyl cyclase and nifedipine did not change CEO‐ and E‐induced relaxation responses. The current results suggest that CEO and the major compound of the essential oil, E improved diabetes‐induced ED in rats, and CEO caused CC relaxation via K+ channels independently NO signalling pathway.
