应用液液萃取与分馏技术定性绵柔型蓝色经典微量挥发性成分

摘要

Volatile compounds of supple and mellow flavor type in Yanghe＇s Lansejidian liquor were isolated and separated by liquid-liquid extraction （LLE） and ffactionation. The total of 933 peak were detected, and 672 compounds were identified by gas chromatography-mass spectrometry （GC-MS）. Of these, 261 volatiles were unknown. These compounds were alcohols, aldehydes, ketones, fatty acids, esters, aromatic compounds, phenols, sulfur-containing compounds, furans, epoxy compounds, acetals, pyrroles, pyridines, lactones, and terpenes. Lactones and terpenes were first detected in Chinese liquors.%应用液液萃取和分馏技术研究了绵柔型洋河蓝色经典酒微量挥发性成分,经GC-MS检测,共检测到933个峰,已经鉴定的化合物672种,未鉴定但有色谱峰的化合物261种。白酒微量成分除原先检测到的醇类、醛类、酮类、酸类、酯类、芳香族、酚类、硫化物、呋喃类、氧杂环/环氧化合物、缩醛类、吡咯及吡啶类等化合物外,首次检测到萜烯与内酯类化合物。
