E. Bylaite et al., INFLUENCE OF HARVESTING TIME ON THE COMPOSITION OF VOLATILE COMPONENTS IN DIFFERENT ANATOMICAL PARTS OF LOVAGE (LEVISTICUM-OFFICINALE KOCH.), Journal of agricultural and food chemistry, 46(9), 1998, pp. 3735-3740
The essential oils from different botanical parts (leaves, stems, flow
ers, and seeds) of lovage (Levisticum officinale Koch.) were analyzed
at various phases of plant growth. The seasonal changes in leaves were
less considerable than in the stems. Seeds and flowers possessed the
highest yield of oil. alpha-Terpinyl acetate was found to be the domin
ating compound in leaves and stems (up to 70%), beta-phellandrene in s
eeds and flowers (61.50% and 40.80%, respectively); Z-ligustilide was
confirmed as a major lovage phthalide constituting from 4.40% to 11.70
% in leaves and from 4.80% to 13.80% in the stem's essential oils depe
nding on the harvesting time.
