Eight new linear polyacetylene glucosides (1-8), containing two C(10)-, one C(13)- and five C(14)-acetylenes, together with three known polyacetylenes (9-11) were isolated from the florets of Carthamus tinctorius L. Their structures were elucidated by means of spectroscopic methods and chemical evidence. The absolute configurations of compounds 3-9 were confirmed by Snatzke and Gerards's method, observing
从小花的小花中分离出八个新的线性聚乙炔葡糖苷(1-8),含两个C(10)-,一个C(13)-和五个C(14)-乙炔,以及三个已知的聚乙炔(9-11)。 Carthamus tinctorius L.通过光谱学方法和化学证据阐明了它们的结构。化合物3-9的绝对构型已通过Snatzke和Gerards的方法得到证实,观察到在CHCl(3)中加入四(三氟乙酸)二铑(Rh(2)(OCOCF(3))(4)]后诱导的圆二色性。还测试了所有分离的化合物(1-11)对小鼠巨噬细胞中LPS诱导的NO产生的抑制活性,并且在1×10(-5)M的浓度下仅表现出弱的活性。
