Antifungal, physicochemical, and insect-repelling activity of the essential oil of Ocimum basilicum

Abstract

The essential oil of Ocimum basilicum at a dose of 1.5 mL/L completely inhibited the mycelial growth of 22 species of fungi, including the mycotoxin-producing strains of Aspergillus flavus and Aspergillus parasiticus. It also proved to repel the insect Allacophora foveicollis. The toxic dose of the oil against the test fungi was much lower than that of some commercial fungicides and fumigants, and it remains unaffected by temperature treatment, storage, and increased inoculum.

Furcatin Hydrolase from Viburnum furcatum Blume Is a Novel Disaccharide-specific Acuminosidase in Glycosyl Hydrolase Family 1

“…The leaves of this plant contain a large amount of furcatin (approximately 1% (w/w) of fresh leaves). In addition, the aglycone p-allylphenol is known to have fungicide, insect-repelling, larva growth-inhibitory, and nematocide activity (8,43,44). Many plant ␤-glucosidases (e.g.…”

Phytoinhibition of Growth and Aflatoxin Biosynthesis in Toxigenic Fungi

“…The antifungal activity of thyme, spearmint and basil was also demonstrated by Montes-Belmont and Carvajall (1998) and Basilico and Basilico (1999) on the toxigenic fungi Aspergillus flavus, Aspergillus parasiticus, Aspergillus ochraceus, Aspergillus fumigatus and Fusarium spp. The antifungal activity of mint, basil and thyme on some pathogenic fungi, including Aspergillus flavus and Aspergillus parasiticus has also been reported which suggested their inhibitory effects on the sporulation of fungi and aflatoxin production [Ela et al, 1996;Inouye et al, 1998;Inouye et al, 2000;El-Maraghy, 1995;Dube et al, 1989]. These effects could be related to several components known to have biological activities, such aspinene, -pinene in thyme, basil and spearmint, respectively.…”

Chemical Compositions, Antioxidant and Antimicrobial Activities of the Essential Oil and Extracts of Lamiaceae Family (Ocimum basilicum and Thymbra spicata) from Turkey

“…Its oil has been found to be beneficial for the alleviation of mental fatigue, colds, spasms, rhinitis, and as a first aid treatment for wasp stings and snake bites. The essential oil has antioxidant, physicochemical and insect-repelling anticonvulsant, hypnotic, and antioxidant activities [7][8][9]. Various researchers have reported chemical composition of the essential oil of O. basilicum [8,9].…”

“…The essential oil has antioxidant, physicochemical and insect-repelling anticonvulsant, hypnotic, and antioxidant activities [7][8][9]. Various researchers have reported chemical composition of the essential oil of O. basilicum [8,9]. They are regarded as oil-rich on the basis of their essential oil contents.…”
