tropical areas. In the Arequipa - Peru region, there are three species, one of them being T. fulva subsp. arequipensis, which was collected in the Sogay district at 2 600 m.s.n.m. of the Arequipa region. The volatile components were extracted by steam distillation in water, the yield was 0.40% in fresh sample leaves and flowers, obtaining a whitresin, density 0.85 g / mL, refractive index 1.464 at 20°C and soluble in ethanol; the presence of terpenes was detected by thin layer chromatography. By the extraction method of maceration in dichloromethane and petroleum ether of leaves and flowers of a dry sample with 13 % residual humidity, it was concentrated in a rotary evaporator obtaining 5.4 % of dry extract, the extract was analyzed by gas chromatography coupled to In a mass spectrum (GC/MS), 11 components were identified in leaves, the majority component being terpinen-4-ol with 37.45 ...
