To determine fragrance character of Spirit “Bai” from Shandong. Spirit “Lu”was positive control, “Er”, egative control, three samples were extracted with either,then analyzed qualitatively and quantitatively with ISTD N-amyl acetate (EP) by gas chromatography-mass spectrometry (GC/MS). Fragranter components including ethyl acid ester(E),butanotic acid ester (B),lactic acid ester (L), pentoic acid ester(p), and hexanoic acid ester(H) were chosen.
