Abstract:

The chemical constituents of volatile oil from Lingdera thomsonii Allen was analyzed by GC-MS. The volatile oil was extracted by steam distillation with a yield of 0.55%. A total of 29 constituents were isolated and among them 24 compounds were identified, content of which accounted for 98.89% of total constituents. Most of these constituents were sesquiterpenes or oxygenated compounds, such as 1,7,7-trimethyl-bicyclo[2.2.1]-hept-2-ylester. The peaks appearing at retention time of 45.16 min correspond to acetate retinal and oxidation ledene, suggesting they may exist in the volatile oil.

Key words: Lingdera thomsonii Allen, volatile oil, GC-MS
