“…In another study, Yilar et al investigated the antifungal effects of vitex extract on some fungi. The tests revealed that this extract had a high range of antifungal effects, such that 5 µl of vitex essential oil reduced 90.23%, 55.68% and 63.35% of the mycelial growth in Verticillium dahlia , Sclerotinia sclerotiorum, and Rhizoctonia solani , respectively [ 19 ]. Asdadi et al evaluated the antifungal effect of vertex seed extract on four Candida species isolated from cases of nosocomial infection.…”

Background and Purpose:Vulvovaginal candidiasis is one of the most common infections in female genital organs, which is caused by Candida species. Candida albicans is the causative agent of more than 80% of infections, and the role of non-Candida strains in the disease etiology is less prominent. The expansion of Azoles resistance among C. albicans strains is considered an important medical problem. According to previous studies, Vitex agnus-castus (vitex) has some antimicrobial effects. We aimed to evaluate the anti-fungal effects of aqueous and alcoholic extracts of vitex against clinical vaginal isolates of C. albicans in comparison with fluconazole.Materials and Methods:Gas chromatography-mass spectrometry analysis was performed on vitex to identify its possible bioactive components. Forty C. albicans clinical isolates were identified by using germ tube, chlamydospore production, culture on CHROMagar, and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Finally, after the extraction of vitex, drug susceptibility test was carried out according to the clinical laboratory standards institute (CLSI) M27-S4 document guidelines.Results:The major chemical components of vitex leaf as determined by gas chromatography included α-Pinene, isoterpinolene, caryophyllene, and azulene. The minimum inhibitory concentrations (MICs) of aqueous and alcoholic extracts of vitex, as well as fluconazole were within the ranges of 15.62–62.5, 7.81–15.62, and 0.25–8 μg/mL, respectively.Conclusion:Our findings showed that the alcoholic and aqueous extracts of vitex had antifungal activity against clinical isolates of C. albicans. Moreover, the alcoholic extract of vitex and fluconazole were more effective against clinical vaginal isolates of C. albicans compared to the aqueous extract of vitex.

“…Etheric and ethanolic extracts of V. agnus-castus had good antimicrobial activities (Pepeljnjak et al 1996). Furthermore, compounds such as 1,8-cineole (eucalyptol) and (E)-b caryophyllene, and sabinene have reported antimicrobial activities (Novak et al 2005;Marongiu et al 2010;Yilar et al 2016), that is, Aspergillus apple rot has been reduced significantly by applying of 1,8-cineole that isolated from V. agnus-castus essential oil (Stojkovi c et al 2011). Fusarium oxysporum, Rhizoctonia solani, Sclerotinia sclerotiorum and Verticillium dahlia were inhibited significantly by applying the oil of Vitex, which contains eucalyptol (1,8-cineole) (17Á75%) and 8-caryophyllene (13Á21%) as the main compounds (Yilar et al 2016).…”

Aims Wood as a packing tool is used for packaging and transportation of fruits and vegetables for a time period varying from hours to days. During transportation, fruits and vegetables can be affected by moulds with significant postharvest problems. The present study describes the possibility of using wood‐treated oil fungicide of n‐hexane extracts from Eucalyptus camaldulensis (aerial parts), Vitex agenus‐castus (leaves) and Matricaria chamomilla (flowers) against the infestation of Fusarium culmorum, Rhizoctonia solani and Penicillium chrysogenum. Methods and Results Air‐dried wood samples of Melia azedarach were prepared with the dimensions of 0·5 × 1 × 2 cm and treated with the oily extracts at the concentrations of 0, 1, 2 and 3%. Oils extracted with n‐hexane from E. camaldulensis and V. agenus‐castus showed promising antifungal activities against the isolated and molecularly identified three fungi F. culmorum, R. solani and P. chrysogenum, while M. chamomilla observed the lowest activity against the studied fungi. GC/MS analysis of oils reported that the major components in E. camaldulensis were β‐fenchol (25·51%), Cyclobuta[1,2:3,4]dicyclooctene‐1,7(2H,6bH)‐dione,dodecahydro,(6αβ,6βα,12αα,12ββ)‐ (17·05), 1,8‐cineole (eucalyptol) (12·01%) and sabinene (9·45%); in V. agenus‐castus were eucalyptol (22·17%), (E)‐β‐caryophyllene (18·39%), and β‐sitosterol (12·44%); while in M. chamomilla were bisabolol oxide A (27·87%), (Z)‐β‐farnesene (16·11%), D‐limonene (14·18%) and chamazulene (11·27%). Conclusions The results suggest using n‐hexane oily extracts from E. camaldulensis and V. agenus‐castus as a biofungicide for wood protection. Significance and Impact of the Study This study highlights the importance of using bio‐friendly fungicide agents to protect wood against most common moulds occurring during handling of food packaging.

“…Further, 1,8-cineole has been proven to have good antifungal activity against Aspergillus apple rot [21]. V. agnus-castus oil contains the main compounds of 1,8-cineole (eucalyptol) and 8-caryophyllene, which significantly inhibited the growth of F. oxysporum, R. solani, Sclerotinia sclerotiorum, and Verticillium dahlia [68]. Melia azedarach wood-treated with the n-hexane oil of V. agenus-castus leaves at a 1%, 2%, or 3% concentration showed good antifungal activity against F. culmorum, Rhizoctonia solani, and P. chrysogenum [9], where the main compounds were eucalyptol (22.1%), (E)-β-caryophyllene (18.3%), and β-sitosterol (12.4%).…”

In this work, the essential oils (EOs) from Eriocephalus africanus leaf, Vitex agnus-castus leaf and fruit, Cymbopogon citratus leaf, and Rosmarinus officinalis leaf were used as antifungal agents against isolated Aspergillus flavus, Cladosporium cladosporioides, and Penicillium chrysogenum from an ancient Egyptian child’s mummy. The isolated fungi were used to colonize the samples of linen fibers. The best oil was used as a novel natural product for the cleaner production of model linen fibers similar to those used in ancient Egyptian mummification. Standard and original linen fibers were compared with the infected Linen samples using Fourier transform infrared (FTIR) and X-ray diffraction (XRD) analyses. The FTIR revealed the changes in the molecular structure of the cellulose, hemicellulose, and lignin of the infected linen fibers. The cellulose crystallinity indices decreased to 64.61%, 52.69%, and 54.63% in the linen inoculated with A. flavus, C. cladosporioides, and P. chrysogenum compared to the control sample (72.08%), thereby affecting the chemical properties of the cellulose. The mycelia inhibition percentages of the three fungi reached 100% after the leaf EO from V. agnus-castus was applied, followed by C. citratus. The V. agnus-castus leaf EO applied at contraptions of 250, 500, 50, 1000, and 2000 µL/mL showed 100% inhibition for A. flavus and P. chrysogenum and reached 100% against C. cladosporioides at concentrations of 500, 750, 1000, and 2000 µL/mL. C. citratus leaf essential oil applied at concentrations of 500, 750, 1000, and 2000 µL/mL showed 100% inhibition to the growth of A. flavus and C. cladosporioides and reached 100% inhibition against the growth of P. chrysogenum at concentrations of 750, 1000 and 2000 µL/mL. This inhibition could be related to the main compounds of caryophyllene (23.13%), eucalyptol (20.59%), sabinene (β-thujene) (12.2%), γ-elemene (9%), and β-farnesene (6.14%) identified in V. agnus-castus leaf EO or due to the main compounds of β-citral (43.63%) and geranial (41.51%), as identified in the leaf EO of C. citratus by GC/MS. The morphological changes in the hyphae of the fungi were observed via SEM examination, where V. agnus-castus leaf EO, the best active oil, showed potent inhibition to fungi grown on the model linen fiber. In this way, the morphology and the structure of the hyphae were effectively changed. Our findings prove that the designed model linen fiber treated with V. agnus-castus leaf EO is able to preserve wrapping fibres and represents a novel natural alternative for effective fungicidal treatment.
