Aiming to valorise the Atlantic Rainforest biodiversity in Santa Catarina, the chemical characterisation of the essential oils (EOs) from leaves of (Spreng.) H. Rob. is described for the first time. Fresh leaves collected in the year 2014 and 2015, were submitted to hydrodistillation to give pale blue EOs in yields of 0.21 and 0.19%, respectively. The EOs were characterised by GC-MS and GC-FID semi- and quantitative methods. The monoterpene β-pinene was the major constituent in both samples reaching a maximum of 26.3%. The monoterpene α-pinene and the sesquiterpene β-caryophyllene, were also among the major constituents in both samples. By means of the extracted ion chromatogram procedure, it was possible to detect chamazulene, which was associated with the pale blue colour of the essential oils. In the antimollicute assays, the essential oil was moderately active against and with MIC values of 250 µg mL.

In this study, we evaluated the antibacterial activities of plant essential oils (EOs) from the Lamiaceae family against Agrobacterium tumefaciens to find new eco-friendly antimicrobials. Thymus vulgaris L. (thyme white) EO demonstrated the most potent fumigant antibacterial activity among these.

Essential oils (EOs) are a promising alternative to conventional pesticides, but some challenges like high volatility, poor water solubility, and rapid degradation limit their use in Integrated Pest Management (IPM). To overcome these limitations, this study aimed to develop garlic, eucalyptus, and clove EO-based nano-emulsions (EO-NEs) in a bait treatment format through the high-pressure microfluidization technique and investigated the biological activities against Ceratitis capitata. In addition, the adverse effects of the most promising nano-emulsion were evaluated towards a non-target parasitoid Anagaspis daci.

Ethnopharmacological Relevance: Myrciaria pilosa is a medicinal species traditionally used to treat inflammation, pain and infectious diseases. Essential oils extracted from medicinal plants have recently gained prominence as adjuvants in combating microbial resistance due to their antimicrobial properties and synergistic potential when combined with conventional antibiotics.
Aim Of The Study: Investigated the chemical composition, antibacterial activity, antibiofilm effects, and antibiotic-enhancing properties of Myrciaria pilosa essential oil.

To develop and characterize a chemically modified chitosan-benzoic acid (CS-BA) nanogel for enhanced encapsulation, stability, and controlled release of essential oils with improved antimicrobial and antioxidant properties, the CS-BA nanogel was synthesized via carbodiimide-mediated coupling (EDC) of chitosan with benzoic acid. The nanogel was characterized using scanning electron microscopy (SEM) for morphology and Fourier transform infrared (FTIR) spectroscopy for chemical bonding analysis. The encapsulation efficiency of essential oils-Pinus roxburghii (PREO), Pinus wallichiana (PWEO), Cedrus deodara (CDEO), Thuja orientalis (TOEO), Cymbopogon citratus (CCEO), Cymbopogon khasianus (CKEO), and Mentha arvensis (MAEO) was evaluated, and in vitro release studies were conducted over 36 h.

Introduction: Basil, an indigenous medicinal herb, is widely used in traditional medicine for its therapeutic and cosmetic benefits. Its properties include reducing oxidative stress, increasing melatonin production, protecting cells from free radical damage, and protecting the skin. Basil can be incorporated into daily skincare routines to address various skin conditions and promote overall health.
