“…Previous research proved that essential oil of Euodiae Fructus had antifungal effects against Candida albicans (MIC = 25.6 mg/mL) and essential oil of Rosa had antifungal activities against Candida albicans (MIC = 25 mg/mL) [ 22 , 23 ]. Here, SEO had antifungal activities (MIC = 3.2 mg/mL).…”

“…The other three main monomers, namely verbenone, terpinolene and α-terpineol, had strong antifungal activities, showing that α-pinene, α-terpineol, terpinolene and verbenone play primary roles in the antifungal activities of SEO against S. cerevisiae and Candida albicans. Previous research proved that essential oil of Euodiae Fructus had antifungal effects against Candida albicans (MIC = 25.6 mg/mL) and essential oil of Rosa had antifungal activities against Candida albicans (MIC = 25 mg/mL) [22,23]. Here, SEO had antifungal activities (MIC = 3.2 mg/mL).…”

Sunflower (Helianthus annuus L.) contains active ingredients, such as flavonoids, alkaloids and tannins. Nevertheless, few studies have focused on essential oil from the receptacle of sunflower (SEO). In this work, we investigated the chemical composition and antimicrobial and antioxidant activities of SEO. The yield of SEO was about 0.42% (v/w) by hydrodistillation. A total of 68 volatile components of SEO were putatively identified by gas chromatography–mass spectrometry (GC-MS). The main constituents of SEO were α-pinene (26.00%), verbenone (7.40%), terpinolene (1.69%) and α-terpineol (1.27%). The minimum inhibitory concentration (MIC) of SEO against P. aeruginosa and S. aureus was 0.2 mg/mL. The MIC of SEO against S. cerevisiae was 3.2 mg/mL. The MIC of SEO against E. coli and Candida albicans was 6.4 mg/mL. The results showed that SEO had high antibacterial and antifungal activities. Three different analytical assays (DPPH, ABTS and iron ion reducing ability) were used to determine the antioxidant activities. The results showed that SEO had antioxidant activities. To summarize, the results in this study demonstrate the possibility for the development and application of SEO in potential natural preservatives and medicines due to its excellent antimicrobial and antioxidant activities.

“…Secondly, further investigation into the mechanism of action of miramistin, ocimene, and thymoquinone would allow for a greater understanding of how these drugs exert their antifungal properties. Researchers have reported that thymoquinone and ocimene potentiate the mode of action of antibiotic compounds; however, research toward ocimene in this area is still lacking [ 67 , 68 , 69 ]. Nevertheless, as the studies conducted by Goyal et al (2017), Liu et al (2019), and Sarah et al (2019) [ 67 , 68 , 69 ] were outside the remit of internationally recognised protocols, their results should be reconfirmed utilising appropriate standard protocols such as those produced by CLSI.…”

The Mould War: Developing an Armamentarium against Fungal Pathogens Utilising Thymoquinone, Ocimene, and Miramistin within Bacterial Cellulose Matrices

An increase in antifungal resistance has seen a surge in fungal wound infections in patients who are immunocompromised resulting from chemotherapy, disease, and burns. Human pathogenic fungi are increasingly becoming resistant to a sparse repertoire of existing antifungal drugs, which has given rise to the need to develop novel treatments for potentially lethal infections. Bacterial cellulose (BC) produced by Gluconacetobacter xylinus has been shown to possess many properties that make it innately useful as a next-generation biopolymer to be utilised as a wound dressing. The current study demonstrates the creation of a pharmacologically active wound dressing by loading antifungal agents into a biopolymer hydrogel to produce a novel wound dressing. Amphotericin B is known to be highly hepatotoxic, which reduces its appeal as an antifungal drug, especially in patients who are immunocompromised. This, coupled with an increase in antifungal resistance, has seen a surge in fungal wound infections in patients who are immunodeficient due to chemotherapy, disease, or injury. Antifungal activity was conducted via Clinical & Laboratory Standards Institute (CLSI) M27, M38, M44, and M51 against Candida auris, Candida albicans, Aspergillus fumigatus, and Aspergillus niger. This study showed that thymoquinone has a comparable antifungal activity to amphotericin B with mean zones of inhibition of 21.425 ± 0.925 mm and 22.53 ± 0.969 mm, respectively. However, the mean survival rate of HEp-2 cells when treated with 50 mg/L amphotericin B was 29.25 ± 0.854% compared to 71.25 ± 1.797% when treated with 50 mg/L thymoquinone. Following cytotoxicity assays against HEp-2 cells, thymoquinone showed a 71.25 ± 3.594% cell survival, whereas amphotericin B had a mean cell survival rate of 29.25 ± 1.708%. The purpose of this study was to compare the efficacy of thymoquinone, ocimene, and miramistin against amphotericin B in the application of novel antifungal dressings.

Sunflower (Helianthus annuus L.) contains active ingredients, such as flavonoids, alkaloids and tannins. However, few studies have focused on essential oils from the receptacle of sunflower (SEOs). The chemical composition, antimicrobial and antioxidant activities of SEOs were assessed whether SEOs could be used as nature preservatives and medicines. The extraction rate of SEOs was 0.4% by using hydro-distillation and solvent with petroleum ether, which is much higher than that by only using hydro-distillation (0.2%) in the previous study. A total of 81 volatile constituents of SEOs were identified by gas chromatography-mass spectrometry (GC-MS). The main constituents of SEOs were α-pinene (31.17%), calamenene (5.66%), α-terpineol (4.71%), verbenone (3.15%), kaur-16-ene (2.52%) and terpinolene (1.47%). The antimicrobial activities of SEOs were assessed against three bacteria (E. coli, P. aeruginosa, and S. aureus) and two fungi (S. cerevisiae and Candida albicans). The MIC of SEOs against P. aeruginosa and S. aureus was 0.2 mg/mL. The MIC of SEOs against S. cerevisiae was 3.2 mg/mL. The MIC of SEOs against E. coli and Candida albicans was 6.4 mg/mL. The results showed that SEOs had high antibacterial and antifungal actions. The antioxidant activity was determined with three different analytical assays (DPPH, ABTS and iron reducing ability). The results of antioxidant activities showed that SEOs had high antioxidant activities. The results proved that SEOs could be used as natural preservatives and medicines, due to its excellent antimicrobial and antioxidant activities.
