摘要
研究大孔吸附树脂纯化木薯叶黄酮的工艺条件,比较大孔树脂HPD100、D151、001×1·1、NKA-9、H103和D101对木薯叶黄酮的吸附性能,并对影响树脂解吸的各种因素进行了研究。在考察的6种树脂中,树脂HPD100最适于木薯叶黄酮的分离纯化,具有较高的吸附性,达208mg/g(干重),同时具有良好解吸性能,用7倍树脂体积的70%乙醇洗脱,解吸率可达96·78%。
The purified condition of macroporous resin was optimized,and the technological parameters of purifying flavonoids in cassava leaves were established.The adsorption and desorption performance of macroporous resins （HPD100,D151 ,001 × 1.1, NKA-9, H103 and D101 ）on flavonoids in cassava leaves were studied,and correlative technical parameters were investigated.Among these six macroporous resins, the optimum macroporous resin HPD100 was screened out, with high desorption （208mg/g dry weight） and desorption rate （96.78%） .70% ethanol： macroporous resin （7： 1, v： v） could accomplish desorption completely.
