Effect of Accessions and Environment Conditions on Coumarin, O-Coumaric and Kaurenoic Acids Levels of Mikania laevigata.

Coumarin, -coumaric, and kaurenoic acid are bioactive compounds usually found in the leaves of . Genetic and environmental variations in the secondary metabolites of plants may have implications for their biological effects. Three different accessions of cultivated in four sites between the Equator and the Tropic of Capricorn in Brazil were evaluated aiming to present potential raw materials and discuss relationships among these three bioactive compounds.
