Extraction of Chinese star anise ( Illicium verum Hooker) and cinnamon bark ( Cinnamomum zeylanicum Nees) was studied by a new solvent extraction technique involving 1,1,2‐trichloro‐1,2,2‐trifluorethane. Thus useful yields of concrete were obtained (21% and 12% respectively). Hydro distillation of the concretes made it possible to obtain essential oils with yields similar to those obtained by direct hydro distillation of plant materials (9.5% and 1.1% respectively). GC‐MS analysis indicated that the composition of products obtained was similar to that of essential oils obtained by direct hydro distillation.
