Chemical composition of Essential Oils of Four Scandix Species from Different Parts: A Chemotaxonomic Approach.

The chemical composition of the essential oils of dried aerial parts of four Scandix species; Scandix aucheri Boiss., Scandix pecten-veneris L. (aerial parts and fruit), Scandix macrorhyncha C.A. Mey. and Scandix balansae Reuter ex Boiss. was analyzed by using GC and GC-MS. The essential oil yield of S. aucheri showed 37 components, which comprised of 98% of the total essential oil and identified 16 constituents in fruit and 18 constituents in aerial part of S. pecten veneris. 10 compounds were identified which comprised 89.6% of the total essential oil from S. macrorhyncha, and 33 constituents were identified in S. balansae and comprised 83.5% in total essential oil. The main compounds were determined as germacrene D (22.3%), spathulenol (11.5%), in S. aucheri; n-hexadecanoic acids (Palmitic) (28.2%), spathulenol (19.6%) in (aerial parts)- n-hexadecanoic acids (27.7%), octadecanoic acids (6.7%) in fruit from S. pecten veneris; n-hexadecanoic acids (31.5%), 1-heptadecanol (25.2%), in S. macrorhyncha, 9,12-octadecanoic acids (Linoleic) (26.6%), 9-octadecanoic acids (oleic) (15.3%), n-hexadecanoic acids (10.7%) in S. balansae. Fatty acid, sesquiterpene and saturated hydrocarbons were determined as significant compounds for the characterization of Scandix species essential oil. The results were discussed in view of natural products and chemotaxonomy. [ABSTRACT FROM AUTHOR]
