摘要
以从栀子属植物的果实中提取的环烯醚萜类化合物京尼平为代表,研究其与皮胶原的反应性。采用UV、TLC等方法并结合已有的文献资料,探讨了京尼平与皮胶原的反应机理。用DSC法分析了京尼平的鞣制效果,并对最佳鞣制条件(京尼平的用量、鞣制时间、鞣液温度及pH值等)进行了筛选。结果表明:用干皮粉质量5%的京尼平,在pH=7·5左右鞣制24h后,其DSC曲线的Tp可达到85℃,同时皮粉被染成深蓝色。因此我们认为,京尼平可以作为皮革工业的一种潜在的、可再生的、清洁高效的鞣剂和染料。
Genipin is the iridoid glycoside geniposide isolated from the fruit of Gardenia jasminoides Ellis. UV, TLC method was used to investigate the reactivity of genipin with leather fibers and their reaction theory. The tanning property of genipin, as well as the tanning conditions such as dosage of genipin, time, temperature and pH value etc was analyzed by DSC. The results show that the Tp of DSC curve reachs 85℃ and the hide powder becomes dark blue color under the following condition : dosage of ginipin is 5% of dried hide powder, pH value is 7. 5, tanning time is 24h. Therefore genipin could be used as a potential, regenerative, cleansing and effective tanning agent and dyestuff.
