摘　　要：本文研究了甲酸、乙酸、丙酸、已酸和环已烷酸缓冲溶液对水解类鞣质亲水性的影响。结果表明,鞣质的溶解度随酸根浓度的增加而明显增加,酸根所含的脂肪碳原子越多,对鞣质的溶解度增加的促进作用越明显。这表明,植物鞣质的疏水基团(如棓酰基)与有机酸根的脂肪链发生了疏水结合。With four typical hydrolysable plant polyphenois,the relation between vegetable tannin structures and their hydrophobic properties had been investigated.The results indicated that the galloyl group in tannin is the hydrophobic one.That is,the more galloyl groups the tan- nins contain,the stronger the hydrophobic property they have.The neutral salts enhanced the hydrophobic property of vegetable tannin obviously.
