ACCESSES OF MENTRASTO.This study aimed to analyse the content and the composition of the essential oil of five accesses of mentrasto (Ageratum conyzoides).Five accesses of mentrasto with three repetitions were used.The accesses were obtained in Mariana-MG (AMA), Piranga-MG (API), Visconde do Rio Branco (ARB) and Viçosa-MG (AVB and AVP).The essential oil was obtained by hydrodistillation and the identification of the oil components by CG and GC/MS.The ARB access presented the higher essential oil content, that is 0.70% (P < 0.05).Eleven chemical compounds were identified.The precocene I was the main constituent in the access API, and the precocene II was the main constituent in the accesses AMA, ARB, AVB and AVP.
