Chemical Composition of the Essential Oil of Pimpinella isaurica Matthews subsp. isaurica

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.
