A total of 46 compounds were identified, including eight alcohols, four aldehydes, one acid, 25 terpenes, seven ketones, and one heterocyclic compound. UAE and MAE had 36 and 38 compounds respectively, sharing similar compositional profiles but differing in concentrations, while HRE produced only 25 compounds Sensory evaluation and E-Nose results revealed differences in the aroma profiles of the extracts, with UAE and MAE extracts exhibiting intensified floral and sweet notes, whereas HRE displayed prominent green and spicy characteristics. K-means clustering categorized volatile evolution trends into four distinct subclasses. OPLS-DA identified 13 differential volatiles with variable importance in projection greater than 1, with ROAV analysis further selecting eight key markers, including (1R,7\n                      <jats:italic>S<\/jats:italic>\n                      )-germacra-4(15),5,10(14)-trien-1\n                      <jats:italic>\u03b2<\/jats:italic>\n                      -ol,\n                      <jats:italic>\u03b1<\/jats:italic>\n                      -humulene, copaene,\n                      <jats:italic>\u03b2<\/jats:italic>\n                      -cadinene, (E)-\n                      <jats:italic>\u03b2<\/jats:italic>\n                      -caryophylene,\n                      <jats:italic>\u0393<\/jats:italic>\n                      -cadinene, humulene oxide II, and caryophyllene oxide.
