摘　　要：通过染色试验,研究了环烯醚萜化合物与蛋白质纤维(皮胶原、蚕丝、白发)的染色条件,探讨了所产生的颜色与蛋白质纤维的种类以及环烯醚萜的分子结构的关系。结果表明:天然环烯醚萜类化合物以单体形式与蛋白质发生交联反应,从而产生颜色。这说明其染色机理与传统的天然染料或活性染料有本质的区别。其反应条件温和(35℃左右、弱碱性(pH=7.5～8.0水溶液中、较短时间内(2h左右))。用环烯醚萜化合物染蛋白质纤维时,所呈现出的颜色不仅与环烯醚萜的分子结构密切相关,而且与蛋白质纤维的种类有一定的关系。环烯醚萜很可能作为一类新型的天然活性染料,不仅可以用于皮革、裘皮、丝绸、毛制品的染色,还可以用于制备安全、环保的染发剂。The relationship between dyeing property and molecular structure of iridoid compounds were investigated by dyeing protein fibers, such as collagen, silk and white hair. The experimental results indicated that the natural iridoids could react with protein fibers under a mild condition （ 35 ℃, pH = 7.5 - 8.0 ）, for a short time （ 1 h） and with a low dosage （ 3 % - 5 % （w/w） of fiber）. The induced color could be attributed to the chemical reaction between iridoid compounds and protein fibers, and closely related to the molecular structure of iridoids, and kinds of protein fibers as well. The iridoid compounds, as a natural reactive dye- stuff, might be suitable for dye of leather, fur, silk and wool, and for preparation of the hair - dye with safe and enrironmental property.
