This study characterizes the volatile aromatic and metabolite components of domestic native Apocynum lancifolium blossom. The accurate characterization of fragrances collected from the blossom was carried out using gas chromatography-mass. A total of 70 chemical components were identified, including ketones of acetophenone (29.22%), phenylethyl alcohol (10.54%), methyl-benzenemethanol (8.43%), benzyl alcohol (7.97%), natural bicyclic sesquiterpene types of caryophyllene (6.08%), gurjunene (6.20%), humulene (1.90%), and ocimene (1.04%). Overall, the content of ketones, alcohols, and terpenes was higher than that of others. The major metabolite components were pentanoic acid, malic acid, fructofuranoside, quinic acid, tagatose, sorbose, galactose, inositol, galactaric acid, glucopyranoside, and octadecenoic acid.
