Objective: To study the volatile oil and fat-soluble components of Alectoria jubata.Method: The volatile oil and fat-soluble components were analyzed by gas chromatography-mass spectrometry (GC-MS).Result: The 34 volatile oil compounds were identified in the extracts of A. jubata

accounting for 17.93% of the total constituents. Terpenes (6.71%)

ketones (4.19%)

alcohols (3.27%) were the main compound types in the volatile oil. Its major components included 4-penten-2-one(4.19%)

cis-7-tetradecen-1-ol (3.03%)

3

7-dimethyl-1-octene (1.30%)

neohexane (1.28%) and germacrene D (1.01%). Meanwhile 33 fat-soluble components were identified in the extracts of A. jubata

accounting for 89.63% of the total constituents. Fatty acids (81.65%)

alkanes (4.49%) and alcohols (1.67%) were the main compound types in the fat-soluble components. Its major components included linolelaidic acid methyl ester (34.98%)

oleic acid methyl ester (10.94%)

pentadecanoic acid 14-methyl-

methyl ester (7.40%) and octadecanoic acid methyl ester (4.13%).Conclusion: The volatile oil and fat-soluble components were extracted and the compounds were identified for the first time. This research could provide a scientific basis for further research and development of A. jubata.
