%X This study aimed to evaluate the production of essential oil from three chemotypes for experiment 1 and four accessions of L. alba from different municipalities in southern Tocantins for experiment 2, with these three repetitions, the design of randomized blocks. The essential oil was obtained via hydrodistillation in Clevenger apparatus. Were evaluated: dry weight, content and yield of essential oil per plant. In experiment 1 there was no statistically significant difference in any of the variables analyzed. In the second experiment, there was significant difference between treatments in Gurupi / Cariri in relation to access to Figueir¨®polis / Alvorada with regard to oil content, which did not differ on the characteristics analyzed for dry mass, when analyzed if the yield per plant was a significant difference between the fits of Gurupi and Cariri in relation to access to Figueir¨®polis and Alvorada.
