The essential oil from leaves of P. aduncum collected in the Brazilian Cerrado, North of Minas Gerais, as well as to evaluate the larvicidal activity of this oil and of its major constituent 1,8-cineole, showed to be very different from those obtained from the same species.
Biosynthesis significance of iridoids in chemosystematics
Iridoids represent a large group of monoterpenoid compounds that apparently seem to be formed in plants by an alternative cyclization of geranyl diphosphate. The structures of these compounds are…
