【摘要】 从螺旋藻中提取藻胆蛋白，用甲醇解离其硫醚键得藻蓝素。其最佳解离条件是：温度为４０℃，解离时间为２４ｈ，Ｖ（甲醇）∶ｍ （藻胆蛋白） ＝２００∶１ 。提取率可达１－５％ ，产物的ＵＶ，ＩＲ和文献相符。藻蓝素发色团在酸性溶液中呈比较扩展型，而在中性溶液中呈比较闭合的结构。更多还原

【Abstract】 The chromophore of phycobiliproteins,phycocyanobilin,was cleaved from the protein of Spirulina Platensis with methanol.The conditions affecting the cleavage of phycocyanobilin were investigated.The optimum conditions were as follows:cleavage temperature 40℃,cleavage time 24 hours and methanol/phycobiliproteins 200∶1(V/m).The extracting yield of the product reached 1 5%.Its UV and IR spectral data were compatible with those in the literature.The conformation variation of phycocyanobilin in different solutions was studied.更多还原
