Biomass production, essential oil’s yield and composition of three genotypes of Mikania laevigata Sch. Bip. ex Baker

Mikania laevigata leaves are used worldwide as herbal medicines. Our study investigates the production differences among three different genotypes of this herb: genotypes’ influence on essential oil yield, chemical composition, and plant tissues involved in secretion compounds produced by leaves. The performed analysis during summer winter seasons. Plants were grown under an organic cultivation system Oratórios, Minas Gerais, Brazil. Essential oils extracted hydrodistillation analyzed gas chromatography/mass spectrometer. highlighted substantial genetic variability genotypes. genotype CENARGEN showed higher biomass production, a high concentration major constituents detected chromatographic oils, such germacrene D caryophyllene oxide. season affected composition oils. Germacrene bicyclogermacrene winter-essential-oils; spatulenol oxide summer-essential-oils.
