[Quality control of essential oil of muscat sage (Salvia sclarea) during laboratory and industrial preparation. IV. Causes of color changes].
Essential oils of muscat sage--of various habitats in different developmental stages as well as the essential oils prepared with half industrial and laboratorial procedures--have been studied. It has been found that compositions of essential oils do not differ significantly, the difference is only in such an extent that could be expected on the ground of environmental and ontogenetic effects. On the basis of tests it has been established that formation of brown oil is in connection with content of copper of apparatus (boiler, tube); Therefore applications of vessel and connections containing copper or copper impurities must be avoided in preparation of the clear essential oil.
