“…In another study, by incorporating CAEO in ChiNPs (20–60 nm), antioxidant and antimicrobial effects were improved [ 36 ]. Chitosan nanoemulsion containing CSEO as a green fruit juice preservative was also reported [ 37 ]. In another report, CLEO was encapsulated in chitosan/hicap with a mean particle size of 339.3 nm; it was concluded that due to the desirable physicochemical properties and thermal stability, this formulation could be used in medicine and food industries [ 38 ].…”

Background Melanoma and breast cancers are two common cancers worldwide. Due to the side effects of chemotherapy drugs and the occurring resistance against them, the development of green drugs has been received more attention. Methods The anticancer effects of three essential oils from the Citrus family and their identified major constituents (limonene) were first investigated against melanoma and breast cancer cell lines (A-375 and MDA-MB-468). By preparing chitosan nanoparticles containing them, an attempt was then made to improve their effectiveness. Results Chitosan nanoparticles containing Citrus sinensis and Citrus limon essential oils with IC50s of 0.03 and 0.124 μg/mL on A-375 cells, and 23.65 and 40.32 μg/mL on MDA-MB-468 showed distinct anticancer efficacies. Conclusion The prepared formulations could thus be considered as green anticancer agents in complementary medicine and therapies.

“…The peels of fresh fruits were cold-pressed, the EO was separated from the crude extract by centrifugation, and stored in the dark in sealed glass vials at 4 °C until use. The composition of this batch of OEO (95.1% limonene, 2.0% myrcene, 0.7% α-pinene, 0.7% sabinene, and 1.5% other compounds) was previously analyzed by Bento, et al [ 20 ].…”

“…Complex essential oil of sweet orange (OEO) is one of the most widely used EOs on an industrial level [ 15 ], widely employed in different fields such as food, cosmetics, pharmaceutics, and agrochemicals [ 16 , 17 , 18 ]. This EO is obtained from the peels of Citrus sinensis (L.) by cold pressing and is composed of more than 20 ICs, including limonene (>85%), myrcene, α-pinene, and sabinene [ 19 , 20 , 21 ]. The excellent antimicrobial properties of OEO can be attributed to that complex composition of ICs, both because of the functional groups that each IC presents and because of the synergism that occurs between them [ 21 , 22 ].…”

Emergence of strains with increased resistance/tolerance to natural antimicrobials was evidenced after cyclic exposure to carvacrol, citral, and (+)-limonene oxide. However, no previous studies have reported the development of resistance and tolerance to complex essential oils (EOs). This study seeks to evaluate the occurrence of Staphylococcus aureus strains resistant and tolerant to a complex orange essential oil (OEO) after prolonged cyclic treatments at low concentrations. Phenotypic characterization of evolved strains revealed an increase of minimum inhibitory and bactericidal concentration for OEO, a better growth fitness in presence of OEO, and an enhanced survival to lethal treatments, compared to wild-type strain. However, no significant differences (p > 0.05) in cross-resistance to antibiotics were observed. Mutations in hepT and accA in evolved strains highlight the important role of oxidative stress in the cell response to OEO, as well as the relevance of the cell membrane in the cell response to these natural antimicrobials. This study demonstrates the emergence of S. aureus strains that are resistant and tolerant to EO (Citrus sinensis). This phenomenon should be taken into account to assure the efficacy of natural antimicrobials in the design of food preservation strategies, in cleaning and disinfection protocols, and in clinical applications against resistant bacteria.

“…Chitosan (CS) is a kind of natural high molecular compound generating in the deacetylation of chitin. The CS is colorless and odorless, environmentally friendly with relatively higher adsorption properties [14] and stronger flocculation effect [15], that has already been widely applied in the chemical environmental protection [16,17], food hygiene [18,19], biomedicine [20], papermaking [21], and textile industries [22]. What is more, the hydroxyl group or amino group in the CS molecular would be beneficial to remove other pollutants for it can form into a hydrogen bond with a dye molecule (containing a -N=N-structure) or combine with the heavy metal ions under certain conditions [23].…”

The considerable amount of Cr(VI) pollutants in the aqueous environment is a significant environmental concern that cannot be ignored. A series of novel Mxene–CS inorganic–organic composite nanomaterials synthesized by using the solution reaction method was applied to treat the Cr(VI) contaminated water. The Mxene–CS composites were characterized through SEM (scanning electron microscope), XRD (X–ray diffraction), XPS (X–ray photoelectron spectroscopy), and FTIR (Fourier transform infrared). The XRD patterns (observed at 2θ of 18.1°, 35.8°, 41.5°, and 60.1°) and the FT–IR spectra (-NH2 group for 1635 and 1517 cm−1, and -OH group for 3482 cm−1) illustrated that CS was successfully loaded on the Mxene. The effects of solution pH, the dosage of Mxene–CS, and duration time on the adsorption of Cr(VI) by synthesized Mxene–CS were investigated. The removal efficiency of Cr(VI) was increased from 12.9% to 40.5% with Mxene–CS dosage ranging from 0.02 to 0.12 g/L. The adsorption process could be well fitted by the pseudo–second–order kinetics model, indicating chemisorption occurred. The Langmuir isotherm model could be better to describe the process with a maximum adsorption capacity of 43.1 mg/g. The prepared novel Mxene–CS composite was considered as an alternative for adsorption of heavy metals from wastewater.
