摘要: 本文研究了高效液相色谱-电喷雾串联质谱定性、定量检测砀山酥梨及其制品中的酚类物质。样品中的酚类物质在70min内得到分离,酚类物质由色谱的保留时间、质谱信息和参考文献确定。质谱检测在负离子模式下,利用全扫描模式、多反应检测模式和中性丢失模式进行。本研究在砀山酥梨中共检出酚类27种,主要酚类物质是绿原酸,含量为180mg/L,其次为熊果苷、没食子酸、咖啡酸、咖啡奎宁酸、表儿茶素、儿茶素、柚(皮)苷、芦丁、槲皮素-葡萄糖苷、槲皮素-半乳糖苷、槲皮素-鼠李糖苷、香豆酸-葡萄糖苷、槲皮素-戊糖苷、鼠李糖素-葡萄糖苷、槲皮素等。

Abstract: High performance liquid chromatography( HPLC)-UV detection-electrospray ionization(ESI) mass spectrometry was used to determine qualitatively and quantitatively the phenolic compounds of Dangshan pear and its juice. Phenolic compounds were saperated in 70min, the main groups of phenolic compounds found according to retention times, spectral data and literature references, mass spectrometry in tandem mode with negative ion detection, using full scan, multi reaction monitor and neutral loss model. The major compounds in Dangshan pear were found to be chlorogenic acid, its concentrate was about 180mg/L in fresh fruit, others was found to contain arbutin, gallic acid, caffeic acid, caffeoylquinic acid, catechin, epicatechin, rutin, quercetin-3-galactoside, quercetin-3-xyloside,q uercetin-3-rhamnoside,q uercetina nd soo n.
