This study aimed to determine the volatile compounds of Wuling area Hawk tea by extracting volatile compounds by headspace solid-phase microextraction and needle trap. The results indicated that forty-seven volatile compounds were identified in Hawk tea, which included thirty-two kinds of free volatile compounds and twenty-six kinds of bound volatile compounds. The results showed that the main free volatile compounds were bornyl acetate, cadinol, and α-eudesmol. Bound volatile compounds were γ-eudesmol, α-selinene, and guaiene. There were seventeen free and bound volatile compounds with odor activity value (OAV) greater than 1. Based on the odor characteristics of those identified compounds, it was concluded that free odor of Hawk tea was mainly from decanal, dodecanal, bornyl acetate, spathulenol, undecan-2-one, and hexanal. Bound odor were β-damascenone, spathulenol, linalool, 2-hexanone, D-limonene, undecan-2-one, and decanal.
