摘   要:

Essential oils of the leaf and root of Eryngium foetidum L. from Port Blair (Andaman and Nicobar) and Nadugani (Tamil Nadu) in India were investigated by GC and GC-MS analyses. The oils of the leaf and root from the two locations were found to contain alkanes, alkanals, alkenals, fatty acids, aromatic aldehydes, mono-, sesqui- and diterpenes, aromatic aldehydes and terpene aldehyde esters. The main components of the oil of the leaf from Port Blair were identified as a trimethyl benzaldehyde (16.5 %), dodecanal (4.7 %), muurola- 4,10(14)-dien-1α-ol (10.2 %), neophytadiene isomer (4.5 %), hexahydrofarnesyl acetone (5.5 %), palmitic acid (4.6 %) and phytol (4.9 %). The composition of the root oil from Port Blair was found to be qualitatively similar to that of leaf oil, having the major constituents two isomers of trimethyl benzaldehydes (4.00 % and 57.0 %) and 2-formyl 1,1,5-trimethyl 2,5-cyclohexadien-4-yl-2-methylbutenoate (4.9 %). The leaf and root oils from Nadugani were found to be qualitatively similar but differed widely in their composition from the oils of Port Blair origin. The principal constituents of the oils of the leaf and root from Nadugani were found to be a trimethyl benzaldehyde (14.3 % and 24.1 %), (E)-2-dodecenal (2.8 % and 14.3 %), τ-cadinol (5.1 % and 7.3 %) and α-cadinol (6.9 % and 10.2 %). Many compounds which were hitherto not reported in the essential oils of E. foetidum were identified in the oils from the two locations in India.
