title: Sesquiterpenoids in root exudates of Solanum aethiopicum.
abstract: Five known sesquiterpenoids, solavetivone, lubimin, lubiminoic acid, aethione and lubiminol were isolated from the root exudates recovered from Solanum aethiopicum by a newly proposed method using charcoal. Quantitative analysis of the sesquiterpenoids in the root exudates of S. aethiopicum and S. melongena suggested that relatively large amounts of the sesquiterpenoids were exuded from the roots. Antifungal activity of the sesquiterpenoids against Fusarium oxysporum and Verticillium dahliae was also examined.
