Assessment of chitosan biopolymer encapsulated α-Terpineol against fungal, aflatoxin B1 (AFB1) and free radicals mediated deterioration of stored maize and possible mode of action

Zingiber zerumbet L. essential oil‐based chitosan nanoemulsion as an efficient green preservative against fungi and aflatoxin B1 contamination

“…Our result was found in good agreement with the previous study of Chaudhari, Singh, Singh et al. (2020a) and Deepika, Singh et al. (2020); they reported enhanced antifungal and anti‐AFB 1 activity of α‐terpineol and Monarda citriodora EO while testing their efficacy against A. flavus causing deterioration of stored maize and chia seeds, respectively.…”

“…The result fully support the earlier report of Chaudhari, Singh, Singh et al. (2020c), who suggested the inhibition of MGo upon treatments with EO may probably lead to inhibition of AF production; however, further study should be conducted to know the exact mechanism underlying AF inhibition via MGo. This novel mechanism of anti‐AFB 1 can be employed as a possible tool for the development of AF‐resistant races of functional food varieties through sustainable green transgenic approaches.…”

“…The sterol was extracted by subsequent addition of n‐heptane (5 mL) and then distilled water (2 mL) followed by additional 2 min of vortexing. The transparent upper layer was used for quantitative measurement of ergosterol at the wavelength ranged between 230 and 300 nm (Chaudhari, Singh, Singh et al., 2020a).…”

Terpenoids, Cannabimimetic Ligands, beyond the Cannabis Plant

“…In agreement with this, tea tree oil's antibacterial and antifungal properties were attributed mainly to 1,8-cineol, methyl eugenol, and terpinen-4-ol [131]. Recently, Chaudhari and co-authors reported the efficacy of α-terpineol loaded chitosan nanoemulsion (α-TCsNe) to control AFB1, a secondary metabolite produced by Aspergillus flavus and Aspergillus parasiticus fungi [122]. Included in miscellaneous actions, in addition to bactericidal and antifungal activities, terpineol has been recognized as algaecide [132] and by its natural repellent activity against Tribolium castaneum (H.) [133].…”

“…Terpineol (2-(4-methylcyclohex-3-en-1-yl)propan-2-ol) is a volatile monoterpene alcohol present in the essential oil of Cannabis sativa [120], but also in several medicinal plants, such as Punica granatum L., Rosmarinus officinalis L., and Psidium guajava L. Until this moment, there is no evidence in the literature about the interaction of terpineol with CBR. Nonetheless, this compound shows different pharmacological properties that include antinociceptive [121], antifungal [122], anti-inflammatory [123], and antidiarrheal [124]. Likewise, terpineol analgesic activity has been investigated in different animal models of pain.…”
