Summary: The objective of this study was to evaluate the effect of ChromatiNet on vegetative growth, total antioxidant capacity, phenolic and essential oils (EOs) composition of Lippia gracilis. The results showed that different colors of ChromatiNet influenced the growth, antioxidant capacity, and phytochemical levels of the plant. Red and black ChromatiNet favored shoot dry weight, thymol, carvacrol, and (E)-caryophyllene accumulation, while sunlight favored root growth, EOs, caryophyllene oxide, p-cymene, flavonoids, orientin, and isoorientin accumulation. Blue ChromatiNet promoted growth, EOs, flavonoids, and photosynthetic pigment accumulation. Therefore, Lippia gracilis plants exhibit plasticity in response to the spectral quality of light, and their cultivation depends on the desired phytochemicals.

Summary: The essential oil extracted from Lippia grata plants showed promising larvicidal activity against dengue vectors, with the oil from the rainy season displaying the best results. The composition of the oil differed from previous studies, suggesting a new chemotype of Lippia grata. The oils also inhibited certain enzymes of the mosquitoes, possibly contributing to their larvicidal effect.

Summary: The composition and biological activities of essential oils in two varieties of Ocimum basilicum (Fino Verde and Genovese) were investigated at different phenological stages. The Fino Verde variety predominantly contained germacrene D and linalool, while the Genovese variety had higher levels of methyl cinnamate and linalool. Both varieties showed high antioxidant and antifungal activities at the flowering stage.

Summary: This study analyzed the chemical composition of Centipeda minima essential oil (EOCM) using GC-MS, and found that the main constituents were trans-chrysanthenyl acetate, thymol, aromadendrene, and beta-caryophyllene. The antibacterial screening revealed that thymol and carvacrol, two monomers in EOCM, exhibited antibacterial activity against S. aureus. The minimum inhibitory concentrations (MIC) of EOCM, thymol, and carvacrol were 0.625 mg/mL, 0.156 mg/mL, and 0.156 mg/mL, respectively. The experimental results demonstrated that these three drugs could inhibit the growth of S. aureus and the formation of biofilm by altering the permeability of cell membrane and interfering with bacterial metabolic activities. The scavenging effects on DPPH radical and hydroxyl radical indicated that the antioxidant effect of the three drugs was EOCM > carvacrol > thymol.
