RESUMO
GC analysis of the dichloromethane extracts obtained from cultivated specimens of Mikania glomerata Sprengel possibilited to verify that cuttings technique led to production of kaurenoic acid and coumarin while the same results have not been observed by propagation process using in vitro techniques.
A análise realizada por CG dos extratos diclorometânicos das folhas de Mikania glomerata Sprengel mostrou que a planta propagada por estaca produziu cumarina e ácido caurenóico, enquanto que o material micropropagado acumulou apenas cumarina.
RESUMO
Dichloromethane crude extract from xylopodium of Calea uniflora Less (Heliantheae-Asteraceae) showed in vitro trypanocidal activity against trypomastigote forms of Trypanosoma cruzi. The data obtained allow to conclude that the crude extract must be investigate to identify its active compounds.
