Abstract

The volatile components extracted from needles of four Picea Mill. species (P. pungens Engelm., P. mariana (Mill.) Britton, P. glauca (Moench) Voss., P. rubens Sarg.) were analyzed by HS-SPME / GC–MS. Thirty-one, thirty-four, twenty-seven and twenty-four compounds were identified representing 91.77%, 92.70% 92.38%, 94.06% of the oil respectively. The main components were bornylacetate (29.40%), camphor (26.43%), -myrcene (7.47%) and camphene (7.01%) in P. pungens. The main components were camphene (22.03%), bornylacetate (21.64%), -pinene (16.62%) and borneol (7.79%) in P. mariana. The main components were bornylacetate (31.25%), limonene (17.27%), -pinene (15.85%) and camphene (13.65%) in P. glauca. The main components were borneol (12.38%), -pinene (10.36%), germacrene D (9.86%) and -cadinene (8.25%) in P. rubens.
