Ocimum tenuiflorum L.f. (syn O. sanctum L.) (Labiatae) is an ayurvedic medicinal plant from India that was introduced in Northeastern Brazil in 1970. Oils produced by steam distillation and microwave distillation from leaves and inflorescences were analyzed by GC/MS and retention indices. The leaf oil contained eugenol (79.0-82.7%) and beta-caryophyllene (7.9-9.8%) as major constituents, whereas the inflorescence oil was rich in eugenol (17.6-60.0%), beta-caryophyllene (24.5-40.7%) and caryophyllene oxide (5.9-18.5%).
