Ephedrine occurs as fine, white, odorless crystals or powder and darkens on exposure to light. De plus, elle augmente l'agressivité et permet de faire reculer le seuil de fatigue. De formule brute C10H15ON, l'éphédrine est un alcaloïde extrait des rameaux de plantes de la famille des gnétacées, les éphédras, dont il existe de nombreuses variétés ; celles de Chine, du Tibet et du Pakistan sont les plus employées ; elles poussent généralement à l'état sauvage dans ces régions.Pour extraire l'éphédrine, qui représente 1,8 p. 100 de tous Chem., 63(18), 1991, 2021-2024.ass: Standard non-polar; Column diameter: 0.32 mm; Column length: 12 m; Column type: Capillary; Heat rate: 10 K/min; Start T: 40 C; End T: 290 C; Start time: 1 min; CAS no: 299423; Active phase: SE-30; Carrier gas: He; Phase thickness: 0.25 um; Data type: Normal alkane RI; Authors: Neill, G.P. ; Perrigo, B., A practical gas chromatographic screening procedure for toxicological analysis, Can.Soc.Forens.Sci.J., 9(2), 1975, 69-74.ass: Standard non-polar; Column length: 6 ft; Column type: Packed; Heat rate: 8 K/min; Start T: 130 C; End T: 290 C; End time: 8 min; Start time: 2 min; CAS no: 299423; Active phase: SE-30; Carrier gas: Nitrogen; Substrate: Chromosorb W AW DMS (80-100 mesh); Data type: Normal alkane RI; Authors: Peel, H.W.
