 +**Anethum graveolens herb** \\
 The amounts of aroma constituents of A.graveolens (whole herb, chopped, n-pentane/diethyl ether 1:2) varied widely depending on harvesting time. Five major aroma compounds comprised together 65-80% of the extract: α-phellandrene, β-phellandrene, limonene, p-cymene, and 3,6-dimethyl-2,3,3a,4,5,7a-hexahydrobenzofuran (dill ether). \\  The amounts of aroma constituents of A.graveolens (whole herb, chopped, n-pentane/diethyl ether 1:2) varied widely depending on harvesting time.

-"The dependence of the characteristic odour note of dill herb on the concentration levels of five compounds, having the highest odour units in an extract obtained from the fresh material, was studied. [[http://www.chemspider.com/Chemical-Structure.391432.html|(S)-α-Phellandrene]] was evaluated as the character-impact compound of the dill flavour which was rounded off by an additive effect of (3R,4S,8S)-3,9-epoxy-1-menthene ([[https://de.wikipedia.org/w/index.php?title=Anethofuran|dill ether]]). The contributions of myristicin, methyl 2-methylbutanoate and (R)-limonene to the dill flavour appeared less significant." \\ +Main aroma compounds of fresh dill were α-phellandrene (1980mg/kg), dill ether (398mg/kg), β-phellandrene (275mg/kg), and limonene (100mg/kg). Air-drying and freeze-drying led to severe losses of all aroma compounds, especially of α-phellandrene and dill ether. Aroma content of freeze-dried dill was lower than 10% than of fresh herb, but about four-fold  that of dried dill. \\

 "GC-MS studies on essential oil resulted in the identification of 35 components, which account for the 98.9% of the total amount. The major component was carvone (55.2%) followed by limonene (16.6%), dill apiole (14.4%), and linalool (3.7%). The analysis of acetone extract showed the presence of 25 components, which account for 94.5% of the total amount.
