摘要: 以废弃香蕉皮为原料,采用L9(34)正交试验的方法对提取香蕉皮多糖的条件进行优化筛选,进一步用DEAE-52色谱柱纯化,得多糖组分bpp1、bpp2和bpp3,并利用HPLC分析bpp1分子质量,结果表明:香蕉皮多糖提取最佳工艺条件为温度85℃、浸提时间5h、pH8,提取率为2.75%;bpp1分子质量为442068u。

Abstract: In this study, an orthogonal array design involving 9 experiments of 3 variables at 4 levels was applied to optimize the extraction of crude polysaccharides from banana peels. Polysaccharides bpp1, bpp2 and bpp3 were obtained from the crude extract by DEAE-cellulose ion-exchange chromatography. Molecular weight determination of bpp1 was performed by HPLC. The optimum conditions for extracting polysaccharides from banana peels were found to be extraction at pH 8 and 85 ℃ for 5 h. The yield of crude polysaccharides under the optimized conditions was 2.75%. The molecular weight of bpp1 was measured to be 442068 u.
