Abstract:The reaction sequences applied to essential oil of Piper hispidinervum D.C (long pepper) leads to formation of a multicomponent mixture composed, mainly, by piperonal, safrole, isosafrole and terpinolene. Due to importance of the piperonal for the pharmaceutical industry is that proposed separate it by high performance liquid chromatography. In this paper, it was studied the adsorption and mass transfer phenomena of these compounds using ethanol/water 70/30 (v/v) as mobile phase and C18 as stationary phase at … Show more
