Sesquiterpenes as Phytoalexins and Allelopathic Agents
Chemistry and Biochemistry
The plant origin and structure are given for those sesquiterpenes which have been shown to be active as phytoalexins or allelopathic agents. Potato (Solanum tuberosum), pepper (Capsicum annum), tobacco (Nicotiana species), eggplant (Solanum melongena), tomato (Lycopersicon esculentum) and jimsonweed (Datura stramonium), all members of the Solanaceae, are rich sources of sesquiterpenoid phytoalexins. Over twenty furanosesquiterpenoid phytoalexins have been isolated from sweet potato (Ipomoea batatus). Both elm (Ulmus glabra) and cotton (Gossypium species) have also been sources of sesquiterpenoid phytoalexins. Allelopathic sequiterpenoids have been implicated in a limited number of investigations. Potential sesquiterpenoid allelochemicals have been found in Artemisia absenthium, Ambrosia psilostachya, Cyperus serotinus and Lippia nodiflora.
