Chemical constituents of the volatile compounds from the Cabernet sauvignon,Cabernet gernischt,Chardonnay varieties of wine-grape berries from xiangning County Shanxi province of Loess Plateau region were analyzed and compared by headspace solid-phase micro-extraction(HS-SPME) followed by gas chromatography-mass spectrometry(GC-MS).The result showed 24,20,23 and 27 compounds from Cabernet sauvignon of slope land,Cabernet sauvignon of flat land,Cabernet gernischt and Chardonnay varieties grapes.These volatile compounds belong to five classes whereby their contents decrease in descending order: alcohol,aldehyde,acid and cyclic olefin;as far as single compound concerned,the contents of 1-butanol,hexanal,acetic acid and hexanoic acid were higher.Besides,terrains of vineyards could indeed affect the composition and content of the volatile compounds,although their aromatic profiles were basically consistent.
