Variability of Volatiles of Wild Hops (Humulus lupulus L.) Growing in Eastern Lithuania

Abstract

Wild hop (Humulus lupulus L.) cones were collected in 12 localities of Eastern Lithuania. α-Humulene (11.1–33.4%) dominated in seven oils, myrcene (15.7–21.1%) in four oil samples and γ-elemene (14%) in one oil. The other most prominent constituents of the essential oils were α-humulene (14.2–16.2%), myrcene (7.7–19.3%), β-caryophyllene (7.6–14.5%), (E)-β-farnesene (7.8–10.4%),γ-curcumene (15.8%), ar-curcumene (10.4%), zingiberene (8.4%) and β-bisabolol (11.8–13.5%). Sesquiterpene hydrocarbons comprised the largest group of oil constituents (45.6–73.7%). One hundred and twenty identified compounds made up 83.4–99.5% of the oils.
