Essential oil of Ocimum basilicum L., O.basilicum. var. minimum L. and O.basilicum. var. purpurascens Benth. grown in north-eastern Brazil

摘要

Ocimum basilicum L.occurs everywhere in several forms, varieties and chemotypes whose essential oils presents marked variation on chemical composition. A new analysis of O.basilicum, O.basilicum var. minimum L. and O. basilicum var. purpuracens Beth. growing in north-eastern Brazil showed that O.basilicum var.minimum represented a true estragole chemotype, while the other two species analysed may be considered linalool chemotypes.
