| Abstract: | Volatile oil in Ampelopsis grossedentata were extracted by solid phase micro-extraction, separated and identified by GC-MS, and the relative content was determined by normalization method. 78 components were isolated and 63 compounds were identified, which accounted for 80.6% of volatile oil components. Result showed that the main components of volatile oil in A. grossedentata were： ethanol（16.66%）, 1.3-di-tert-butyl benzene（9.44%）, 2-methyl decane（4.95%）, 2.4-dimethyl-1-decene（4.65%）, 2.4-dimethyl-1-heptene（4.51%）, 7-methy-11-undecene（4.45%）,2.6-dimethyl-nonane（4.36%）, sabinene（1.86%）, α-pinene（1.85%）, ethylformate（1.83%）, tridecane（1.72%）, β-thujone（1.44%）, 1-undecene（1.29%）, 2,3,5,8-tetramethyl-decane（1.27%）, 4.6-dimethyl-dodecane（1.02%）, accounting for 76% of the total volatile compounds. |
