“…The fibres containing only peppermint EO (9% v/v) showed the highest inhibitory effect against E. coli and S. aureus, whereas the addition of chamomile EO enhanced their antioxidant properties. Gelatine fibres with 9% v/v of peppermint EO exhibited a DPPH radical scavenging activity of 50%; while values higher than 60% were collected for fibres with 9% v/v of peppermint/chamomile EOs (Figure 3a), due to the combined action of the two EOs (chamazulen and bisabolene are the main components of chamomile EO) [86]. In another study, the synergistic effect of peppermint EO and copper sulphate was investigated for wound healing applications [51].…”

The extensive and sometimes unregulated use of synthetic chemicals, such as drugs, preservatives, and pesticides, is posing big threats to global health, the environment, and food security. This has stimulated the research of new strategies to deal with bacterial infections in animals and humans and to eradicate pests. Plant extracts, particularly essential oils, have recently emerged as valid alternatives to synthetic drugs, due to their properties which include antibacterial, antifungal, anti-inflammatory, antioxidant, and insecticidal activity. This review discusses the current research on the use of electrospinning to encapsulate essential oils into polymeric nanofibres and achieve controlled release of these bioactive compounds, while protecting them from degradation. The works here analysed demonstrate that the electrospinning process is an effective strategy to preserve the properties of essential oils and create bioactive membranes for biomedical, pharmaceutical, and food packaging applications.

“…The literature in this area contains little data on the active compounds responsible for the antioxidant capacity of EOs. However, a number of studies report the antioxidant potential of chamazulene, the constituent with the highest share in the composition of the EO analyzed in this study [15,23,24]. Previously, Bozin [5], seeking to identify the most active constituents of the EO isolated from A. collina Becker, responsible for the radical scavenging capacity, indicated chamazulene, the mixture of monoand sesquiterpene hydrocarbons and camphor.…”

“…The increasing trend in the last decades for the applications of EOs in the food and pharmaceutical industries prompted the investigation on the biological activities of the members of the genus Achillea. Various studies have reported notable antimicrobial properties of extracts and EOs obtained from various species of Achillea [5,[11][12][13], together with a good antioxidant potential [5,11,14,15]. Although these results suggest the potential applications as antioxidant or antiseptic for the yarrow EO, it is currently only used in the food industry for flavoring certain alcoholic beverages [16].…”

The investigation of the chemical composition, antioxidant and antimicrobial properties of the essential oil of Achillea collina Becker growing wild in western Romania was the aim of this study. The chemical composition of the essential oil was evaluated by GC-MS. The major compounds identified were chamazulene (38.89%), germacrene D (12.90%), β-caryophyllene (11.52%) and β-pinene (10.66%). The antimicrobial activity was assessed by the diffusimetric method against seven common food-related bacteria. No effects were observed against Clostridium perfringens and Streptococcus pyogenes. The antioxidant activity was evaluated using the DPPH test, the essential oil (IC 50 = 25.03±0.12 µg/ml) demonstrated a stronger scavenging effect than BHA and lower than that of ascorbic acid and propyl gallate. The results reveal strong antimicrobial and antioxidant properties of the essential oil tested and contribute to future research to find new sources of natural antiseptics and antioxidants: a viable and safe alternative to reduce the use of synthetic additives.

“…Other prominent compounds were myrcene (9.0%) and germacrene (7.1%). A.macrocephala in Mongolian Trans-Altai Gobi could be more anti-inflammatory activity than others which are growing in different areas of Mongolia because of chamazulene content according to the studies by researchers at Siberian State Medical University showed high anti-inflammatory activities for azulene (derivative product is chamazulene) containing essential oils of wormwood [35]. …”

Abstract:The essential oil compositions of four Artemisia species in Mongolian Trans-Altai Gobi were studied by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). The oil from A.macrocephala Jacq and A.dracunculus Ledeb. were characterized by the presence of monoterpene hydrocarbons and oxygenated monoterpeneoids predominately. E-nerolidol (26.95%), methyleugenol (23.29%) and sabinene (13.21%) were found as main components in the essential oils of A.dracunculus. A.macrocephalla was characterized by the presence of chamazulene (13.8%), cineol (11.7%), myrcene (9.0%), germacrene-D (7.1%). A.anethifolia Web was characterized by the presence of fragrant compounds as camphor (26.05%), α-thujone (10.1%), borneol (5.1%). Davanone and davanone derivatives were also detected in the sample in amount of 7.7% in total. A.scoparia Waldst differed by domination of monoterpene hydrocarbons (78.9%) with (Z)-β-ocimene (29.24%), α-pinene (15.19%), limonene (10.27%) and myrcene (9.61%).
