4 Opiates alkaloids – OPLC alumine oxide –whit ethyl acetate –as mobile phase Not easy in TLC because two classes of alkaloids isoquinolein and morphinan

5 Opiates alkaloids

6 CANNABINOIDS

7 Separation of main Cannabinoids Eluent Iso-octane/Ether : 90 10 v/v external pressure 50 bars eluent flow rate 0.1 mL flash 0.075 mL elution volume 1 mL elution 607 sec

8 Preparative OPLC of cannabinoids (cannabidiol) OPLC TLC control OPLC cannabinol CANNABIDIOL THC

9 Mode préparatif en chimie végétal Extratothéque Intérêt en synthése organique –Séparation de deux produits de synthèse peu facile à séparer en colonne

10 ESSENTIAL OILS

11 Essential oils Separation of two position isomers THYMOL CARVACROL from essential oil of thyme Hexane/ethyl acetate 95/5 v/v on silicagel

12 Study of 7chemotypes of thymes Thymes: Linalool,thuyanol,carvacrol, thymol, lemony,wild,geraniol, borneol.
