Regeneration of plants and production of volatiles from callus cultures ofMelissa officinalis L. 4. volatile components from headspaceanalysis[German]

摘要

Using headspaceanalysis we were able to detect several saturated and single unsaturated C-6-aldehydes, -alcohols and -acetate esters. Normally only tiny amounts of these substances can be extracted by watersteam distillation and only traces of these compounds are emited by living plants. In difference to mono- and sesquiterpenes, the accumulation of C-6-components is rising with time of analysis and the amount of these substances is also rising by a second headspaceanalysis. Due to the accumulation pattern, C-6-aldehydes, -alcohols and -acetate esters are presumably generated during headspaceanalyses by an enzyme system from linolenic and linoleic acid and therefore are not genuine constituents of essential oil.
