The aromatic components in ‘Green No. 9’ peach fruit were extracted by solid phase micro-extraction （SPME） and analyzed by gas chromatography-mass spectrometry（GC-MS）. Results showed that 69 aromatic components belonging to 9 categories were identified, which accounted for 87.22% of the total peak area. The major constituents were aldehydes, alcohols, esters, ketones and hydrocarbons, etc. （E）- 2-hexenal, 4,4′-（1-methylethylidene） bis-phenol, δ-dodecalactone, 1,2-benzene dicarboxylic acid, butyl 8- methylnonyl ester, 7-decalactone, （Z）-acetate-3-hexen-1-ol, acetic acid hexyl ester, β-ionone, etc. , were main aroma components. Cyclopentanol,2-rnethyl , acetate, cis-, bis（2-methylpropyl）ester, etc., might be unique aroma components of ‘Green No. 9 ’peach fruit.
