摘要

Lippia gracilis?essential oil (LGEO)?was evaluated for its molluscicidal activity against?Biomphalaria glabrata?and toxicity to brine shrimps (Artemia salina).?L. gracilis?was collected from the city Tomar do Gerú- Sergipe, Brazil. The LGEO were characterized by?gas chromatography-mass spectrometry (GC/MS). The values of LC10,?LC50?and LC90?were respectively 36.9, 62.2 and 82.8 ppm for?B. glabrata?and 19.6, 23.6 and 26.1 ppm for?A. salina. GC/MS analysis showed a total volatile content of 98.6% in the LGEO. The major components were identified as thymol (24.0%), p-cymene (15.9%), methyl-thymol (11.7%),?g-terpinene (10.9%) and?b-caryophyllene (7.8%).
