| 摘 要： | 为优化柑橘皮中水溶性黄酮类化合物的提取工艺，本文考察了几种树脂对水溶性黄酮的吸附性能。并以95％乙醇为洗脱剂进行了洗脱实验。结果表明：AB-8树脂对水溶性黄酮有很好的吸附性能，最大吸附量为30．2mg／g(水溶性黄酮／湿树脂)；95％乙醇洗脱速度快，洗脱彻底，洗脱剂用量为2倍柱床体积(BV)。用该法提取的产品具有良好的水溶性，最大吸收波长为280n，并且利用高效液相色谱对获得的提取物进行了分离测定。

| Abstract: | In order to optimize the extraction conditions of water-soluble flavones in orange peel, the adsorption abilities of some resins to water-soluble flavones in orange peel have been studied. Furthermore, the desorption conditions of the flavones have also been carried out using a 95% ethanol solution as a desorption reagent. The result indicates that the adsorption ability of AB-8 is the biggest among all resins and its maximum capacity is 30.2mg/g(water-soluble flavones/wet resin). The desorption of the flavones is fast and complete with 95% ethanol when the elution volume is 2 times of bed volume(BV). The flavones obtained by the proposed technique have a good solubility and dispersion in water, and maximum absorbance appears at 280 nm. In addition, the flavones were characterized by HPLC. |
