Anti-fungal sesquiterpenoid from the root exudate of Solanum abutiloides

The Solanum abutiloides plant is highly resistant to soil-borne pathogens such as Fusarium oxysporum f. sp. melongenae, Verticillium dahliae, and Ralstonia solana-cearum. This species is utilized as a mating source of resistant cultivars and is also used as a rootstock. The root exudate of Solanum a...

Description
Summary:The Solanum abutiloides plant is highly resistant to soil-borne pathogens such as Fusarium oxysporum f. sp. melongenae, Verticillium dahliae, and Ralstonia solana-cearum. This species is utilized as a mating source of resistant cultivars and is also used as a rootstock. The root exudate of Solanum abutiloides was extracted from a soil system composed of charcoal and vermiculite. Anti-fungal activity was found in the extract, and an active ingredient was isolated. The chemical structure of the active compound was determined to be 3-Beta-acetoxy-solavetivone, a new sesquiterpenoid. The anti-fungal activity of 3-Beta-acetoxysolavetivone examined by the inhibition of spore germination of Fusarium oxysporum was close to that of lubimin, and higher than that of solavetivone.
