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

Abstract

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.
