摘　　要：选取4种天然环烯醚萜类化合物进行结构修饰,并将修饰产物用于真丝绸的染色,探讨其结构修饰原理和染色机理。利用紫外可见光谱分析呈色反应过程,测试染色牢度,探索增加天然环烯醚萜类化合物衍生物并拓宽其色谱范围的新途径。结果表明:天然环烯醚萜化合物可通过酯水解、苷交换及酰化反应等结构修饰获得相应的衍生物;修饰产物对真丝绸具有很好的染色效果,染色牢度可达到4~5级。Four natural iridoids were selected for structural modification,and the modified products were used for dyeing of silk.The structural modification principle and dyeing mechanism were discussed.Ultraviolet-visible spectroscopy was used to analyze the color reaction process,test the color fastness,and explore a new way to increase the natural iridoid derivatives and broaden their chromatographic range.The results showed that natural iridoid compounds could be modified by ester hydrolysis,glycoside exchange and acylation to obtain corresponding derivatives.The modified product has good dyeing effect on silk,and the dyeing fastness can reach 4-5 grade.
