“…Essential oils are the essence of plants and spices, which are fragrant and distributed throughout different plant organs, such as roots, stems, leaves, flowers, fruits, and seeds [ 5 ]. Essential oils are extracted through different techniques, including steam distillation and organic solvent extraction, supercritical CO 2 extraction, ultrasonic-assisted extraction, ultrasonic extraction, and molecular distillation.…”

Applications for vanilla essential oil extracted from vanilla pods have been limited since the effective components of vanilla could be easily influenced by environmental factors, such as temperature, light, and oxygen, which hinder their effectiveness. In this study, vanilla essential oil was encapsulated in a Pickering emulsion with octenyl succinic acid starch (OSA—starch). The optimal process conditions for emulsion preparation were determined as 5% vanilla essential oil phase with 2.5% OSA—starch when they were ultrusonicated for 3 min at 470 W. Under these conditions, the minimum particle size was 0.456 μm, the oil droplets were completely encased by starch, and no new chemical bonds were formed. The smallest particle size was produced at a pH of 4 and 500 mM ion concentration. The antioxidant activity of the emulsion was greater than that of the pure vanilla oil at the same oil content. After 24 h storage, the antioxidant activity of the emulsion was enhanced, and the vanilla essential oil was slowly released in the emulsion. These results indicated that the vanilla essential oil encapsulated in a Pickering emulsion with octenyl succinic acid starch showed its tremendous potential for use in the food industry.

“…Elemol (n ° 37 with 6.57% to C. nardus) (Table 1) is also reported in the literature as present in some chemotypes in varying concentrations. Among the observed percentages, it can reach 25.38% (CLAIN et al, 2018), what is considered the chemical marker of the genus Cymbopogon collected from the wild population in the south of Reunion Island (CLAIN et al, 2018). However, other references report the absence of this constituent in the chemical composition of species collected in different locations, both cultivated and native.…”

Agroecological products have been demanded by the population due to their low environmental impact. In view of the demand for natural repelent, objective was to characterize the chemical composition of the essential oils of croton and citronella valuate their spatial repellency activities against dengue mosquitoes. The essential oils were hydrodistilled, submitted to gas chromatography and to the repellency test with concentrations of 1, 2, 4 and 10%. DEET was incorporated into the emulsion in the same concentrations as a positive control and the pure non-ionic emulsion as a negative control. The repellency tests were obtained from 20 adult females exposed for 10 min in a cylindrical chambers and glass slides containing the samples. The essential oils of croton showed a yield of 0.37% with 20 compounds. The citronella oil yielded 1.07% with 27 compounds. The best dose of repellency response was 2% for both. Croton showed a repellency rate of 57% and citronella presented one higher than 70%. It is concluded that these species have a repellent action against the dengue mosquitoes.

“…The ABTS radical scavenging activity of extracts was determined using the method described previously [25] with some modifications. The ABTS+ solution was prepared from the reaction of equal volumes of 2.45 mM potassium persulfate and 7 mM ABTS in a dark place at ambient temperature for 16 h. The ABTS+ solution was adjusted to the absorbance of 0.700 ± 0.02 at 734 nm with ethanol.…”

Flos Chrysanthemi indici, an important medicinal and aromatic plant in China, is considered to have many different preservative and pharmacological properties. Considering the capability of essential oils (EOs), the present study is conducted to compare different extraction methods in order to improve yield and biological activities. Hydro-distillation (HD), steam-distillation (SD), solvent-free microwave extraction (SFME), and supercritical fluid extraction (SFE) are employed to prepare EOs from Flos Chrysanthemi indici. A total of 71 compounds are assigned by gas chromatography/mass spectrometry (GC–MS) in comparison with retention indices. These include 32 (HD), 16 (SD), 31 (SFME) and 38 (SFE) compounds. Major constituents of EOs differ according to the extraction methods were heptenol, tricosane, camphor, borneol, and eucalyptol. EOs extracted by SFME exhibit higher antioxidant activity. All EOs show varying degrees of antimicrobial activity, with minimum inhibitory concentration (MIC) ranging from 0.0625 to 0.125 mg/mL and SFME and SFE prove to be efficient extraction methods. EOs alter the hyphal morphology of Alternaria alternata, with visible bumps forming on the mycelium. Overall, these results indicate that the extraction method can significantly influence the composition and biological activity of EOs and SFME and SFE are outstanding methods to extract EOs with high yield and antimicrobial activity.
