CHEMICAL COMPOSITION OF THUJA ORIENTALIS L. FRUITS AT DIFFERENT STAGES OF MATURITY

The essential oil obtained by hydrodistillation of the fruits from Thuja orientalis at two stages was analysed by GC and GC/MS. Among the compounds indentified, a-pinene (41.48-45.61 %), N-carene (32.69-34.55) ~-terpinene (2.28-2.51 %), p-eymene (1.29-2.23%), cedrol (1.82-4.50%), camphene (1.78-1.96%), D-Iimonene (1.47.2.40%) and myrtenol 0.27-4.40%) were found to predominate, while other compounds were either in small quantities (i.e. less than 1%) or in traces.
