Influência da secagem sobre o rendimento e composi？？o química dos compostos voláteis das raízes de Piper piscatorum Trel. & Yunck. (Piperaceae)

in this study, we evaluated the yield and chemical composition of volatile compounds obtained from fresh, dried at 30 and 40 oc respectively of piper piscatorum, employing the technique of hydrodistillation. the volatile were chemically characterized by gc-ms and gc-fid. the main volatile compounds were selin-11-en-4-a-ol (57,63 ± 3,07%; 53,95 ± 1,56% and 56,20 ± 0,43%) and benzyl benzoate (15,40 ± 0,36%; 16,32 ± 0,85% and 15,04 ± 0,24%).the drying of the raw material reduced yield of volatile compounds, changing their chemical compositions.
