Previous studies on the essential oil of M. rotundifolia revealed the existence of chemotypes with different major components, as for example piperitone oxide (Kokkini and Papageorgiou, 1988; Hendriks and Van Os, 1976), menthyl acetate (Kokkini and Papageorgiou, 1988), dihydrocarvone (Hendriks and Van Os, 1976) and also piperitenone oxide (Nagell and Hefendehl, 1974), indicating that the Uruguayan population could be a representant of the chemotype reported for Nagell et al. (Nagell and Hefendehl, 1974)." \\ | "The major constituent was [[http://webbook.nist.gov/cgi/cbook.cgi?ID=C35178553|piperitenone oxide]] (80.8%), an oxigenated monoterpene which has been reported to characterise the volatile oil of some chemotypes of Mentha sp., such as M. spicata (Pino et al., 1998), M. longifolia (Venskutonis, 1996), M. x villosa (Abreu Matos et al., 1999) and M. rotundifolia (Nagell and Hefendehl, 1974).
