Abstract

This work has been partially supported by grants from the DGICYT, Ministry of Education and Science, and the Canarian Autonomous Government (Spain). We thank M. Fernández Galván (ICIA, Tenerife) for his advice on plant collection and classification, and the ICONA staffin in Tenerife for their logistical assistance. D.T. thanks the Ministry of Education and Science (Spain) for a fellowship within the Scientific Iberoamerican Cooperation Program. We gratefully acknowledge Dr. P. Escoubas (SUNBOR, Japan) for insect supply.

Three new diterpenes with the rare isoryanodane skeleton, indicol (7), vignaticol (8), and perseanol (9), have been isolated from Persea indica (Lauraceae). These compounds proved to be antifeedants against Spodoptera litura, perseanol being the most active.
