Resumo
Hyptis marrubioides Epling (“hortelã-do-campo”) is a medicinal species
known for its activities against gastrointestinal and skin infections, pains and cramps. The aim of
this work was to evaluate essential oil content and chemical composition in H. marrubioides of
different genotypes (purple and white), as well as fresh plant parts (leaves, inflorescences and
stem). The studied genotypes were identified based on the inflorescences, which are purple and
white. The experimental design was completely randomized, including the three parts of both
genotypes, in a 3X2 factorial arrangement, with four replicates. Essential oil was extracted through
hydrodistillation for two hours and analyzed using Gas Chromatography attached to a Mass
Spectrometry (GC-MS). The highest essential oil content was found for the inflorescence of purple
genotype. Hyptis marrubioides essential oil composition quantitatively varied among the analyzed
plant parts and between genotypes. The compound -thujone had the highest percentage of apex
area in inflorescences of purple genotype. The percentages of purple genotype were on average
higher than those of white one.
