Resumo
Hyptis suaveolens (L.) Poit. belongs to the Lamiaceae family and is widely used
in folk medicine in various countries. Th e essential oils from H. suaveolens have
been extensively investigated and are mainly composed of monoterpenes and
sesquiterpenes, although signifi cant diterpene content has been reported in
recent studies. Th e survey of the literature concerning H. suaveolens essential oils
revealed a high level of chemical variability in terms of quantity and composition
that is commonly observed for volatile oils from other plant species. However, few
researchers have dealt with the reasons for such chemical variability. Our research
group has been investigating the relationships between growing conditions of the
plants and the H. suaveolens (L.) Poit. essential oil composition. Th e results of these
investigations have led to some advances in the characterization and knowledge
of H. suaveolens chemotypes from Brazil. Nevertheless, since this species presents
high level of genetic polymorphism and allows it to adapt to the alterations in
environmental features resulting in interpopulational and intrapopulational
variability in the volatile oil chemical compositions. Consequently, biochemical
assays on the biosynthetic pathway are required in order to detect the molecular
mechanisms involved in inducing diff erential terpenoid biosynthesis within H.
suaveolens. Th ese are some of the challenges which require resolution leading to
an understanding of the complex secondary metabolism of this species, thereby
making possible the volatile oil chemical standardization seeking productivity and
phytotherapy.
