Essential oil ofPeucedanum oreoselinum fruits collected near Vilnius

Fruits ofPeucedanum oreoselinum (L.) Moench, were collected at three sites in 1995–1998 and contained 1.5–5.0% essential oil. Analyses were performed using GLC and GC-MS. The main component of the essential oil is limonene (44.1–82.4%). The majority of examined samples contained more limonene than has been reported in the literature. Only in sunny locations do plants synthesize significant quantities of γ-terpinene (12.2–17.5%) and β-pinene (8.5–14.5%). Small quantities of α-pinene are present in all studied samples of essential oil (4.0–8.3%). Monoterpenes comprise 97.1–98.6% of the essential oil. The remainder consists of sesquiterpenes.
