Abstract:

The volatile oils extracted from the whole plants of Atriplex tatarica by water steam distillation and Soxhlet extraction were analyzed by GC-MS. The relative content of each component was determined by area normalization. Fifty-three compounds were separated and fifty-one of them were identified from the oil of water steam distillation method, the major constituents are 1-methoxy-4-(1-propenyl)-benzene (45.84%), heptacosane (9.82%), 1H-indol-5-ol (6.81%), benzenacetic acid, ?α-hydroxy-, and 2-methylpropyl ester (4.03%). Twenty-six compounds were separated and twenty-two of them were identified from the oil of Soxhlet extraction method, the major constituents are nonacosane (22.63%), (z,z)-9,12-octadecanoic acid (16.69%), hexadecanal (6.89%), and n-hexadecanoic acid (5.43%).

Key words: Atriplex tatarica, volatile constituents, GC-MS
