Abstract
The essential oil of aerial parts of P. isaurica wild growing in South Anatolia was extracted by using a Clevenger type apparatus, and analysed by GC and GC-MS. The percentage yield of the essential oil from of aerial parts of Pimpinella was 0.2 %. The oil was colourless to pale-yellow in colour. Fifty-three compounds representing 98.0 % of the P. isaurica oil were identified. The major constituents in the oil from the aerial parts of P. isaurica were: sabinene (12.79 %), myrcene (4.43 %), geijerene (24.30 %), terpinene-4-ol (4.71 %), dictamnol (5.82 %), caryophyllene oxide (3.84 %). Caryophyllene oxide was common to all samples. Other compounds were found in the oils but with some quantitative variation. Fifty-three compounds were identified in the aerial parts oil.
