Abstract

The chemical constituents of the oil from Taxodium distichum (L.) were collected in mide of summer , essential oils were extracted from fruit by hydrodistillation method ( clevenger – type apparatus ) which apparatus planed to take oil in runing time without stoping of process. In this extraction we collected three fraction and then oils analyzed by GC and GC/MS . The major constituents in fraction – 1 were a - pinene (61.8%) which decrease in fraction – 2 (57.1%) and in fraction – 3 (14.8%) , and another compound 1- terpineol in fraction – 1 were (31.5%) and in fraction – 2 increased (32.5%) but in fraction – 3 again decreased (24%) and for b - caryophyllene in fraction – 1 with (1.2%) in fraction – 2 are increased (7.2%) and in fraction – 3 again increased (24.6%) .
