摘要
研究了丙酮提取番石榴叶中多酚类物质的最佳条件:体积分数50%丙酮浸提,浸提温度60℃,浸提时间1 h,原料粒度40目;在该条件下总酚得率为14.54%。利用RP-HPLC鉴定了番石榴叶丙酮提取物中多酚类物质,发现了8种酚类物质:山奈素、绿原酸、没食子酸、原儿茶酸、阿魏酸、咖啡酸、槲皮素和卢丁,其中山奈素、绿原酸、没食子酸在番石榴叶中的存在迄今未见报道。
In this paper, the condition of extracting polyphenolic compounds by different solvents was discussed. The optimum extracting condition was determined as： 50% acetone solution, extraction temperature 60℃, extraction time 1h, 40 Mu and the total phenols recovery was 14.54%. In addition, 3 new compounds （gallic acid, chlorogenic acid kaempferol ） and 5 known compounds （procatechuic acid,ferulic acid, caffeic acid, quercetin and rutin ） were identified in the guava leaf extract by RP-HPLC analysis.
