VOLATILE CONSTITUENTS OF THREE PINUS L. SPECIES (PINACEAE) FROM CANADA

Abstract

In this study three Pinus L. taxa from Canada (P. resinosa Sol. ex Aiton, P. flexilis E.James and P. nigra J.F. Arnold) have been studied to determination taxonomical classification based on chemical characters. For this purpose essential oil needless of P. resinosa, P. flexilis and P. nigra were investigated by HS-SPME / GC–MS and twenty nine, thirty two and forty seven components were determined respectively. Caryophyllene (27.60%), -pinene (15.9%), 3-carene (11.4%) and naphthalene (9.37%) in P. resinosa; acetic acid (31.12%), bicyclo (2.2.1) heptan-2-one (21.45%) and germacrene D (6.13%) in P. nigra; -pinene (33.29%), -pinene (16.24%), borneol (8.64%) and limonene (8.06%) in P. flexilis were identified as main components. Consequently, -pinene chemotype was detected in P. resinosa and P. flexilis, whereas acetic acid chemotype was determined in P. nigra. The results have given some clues on the chemotaxonomy of genus and usable potentials of the plants as renewable resources.
