In order to isolate and identify the unpleasa odor of wild hemp leaves, tops of the plant its flowering time was extracted with petroleu ether at first and the residue was extracted wi 90% ethanol. In this ethanol soluble fractic piperidine contained in free and combined for, in hemp was isolated and identified by meal of the paper chromatography analysis and i_??_frared spectra.
The melting point of the picrolonate derive from wild hempen piperidine was 242_??_245°C and that of authentic piperidine was 242_??_244°C The infrared spectra of both picrolonates wei found to be coincident and Anal., found:_??_20.08, calcd. for C15H19N5O5: N, 20.06%.
