摘要:

选择7 种大孔吸附树脂,通过研究其对竹叶黄酮的吸附率和解吸率,筛选出较优的竹叶黄酮吸附剂。结果表明:AB-8 型大孔树脂吸附量大,易于洗脱,纯化分离效果好;获得竹叶黄酮最佳分离纯化工艺参数为上柱溶液pH5.0,以1.0mL/min 的吸附流速上样,用4 倍床体积的60% 乙醇溶液以1.5mL/min 洗脱速率洗脱。该工艺生产的竹叶黄酮纯度达到54.16%。

Abstract:

To screen an optimal adsorbent for purification of flavonoids from bamboo leaves, 7 macroporous resins were compared for difference in adsorption and desorption performance. AB-8 resin was chosen due to the merits of large adsorption capacity, easy desorption and high resolution. Besides, the optimal adsorption/desorption process for purification of bamboo leaf flavonoids using AB-8 resin was investigated. Results showed that the optimal pH and flow rate of sample solution were 5.0 and 1 mL/min, respectively and the optimal desorption was achieved by using 4 BV of 60% aqueous ethanol at a flow rate of 1.5 mL/min. Under such conditions, the purity of bamboo leaf flavonoids obtained was up to 54.16%.

Key words: macroporous resins, bamboo leaves, flavonoids, separation, purification
