Quinone pigments in the crinoids were investigated. New quinone sulfates 1 and 3 were isolated from Tropiometra afra macrodiscus and Oxycomanthus japonicus, respectively. The structures 1 and 3 were determined to be 1,6,8-trihydroxy-3-propylanthraquinone-2-carboxylic acid 6-O-sulfate (ptilometric acid 6-O-sulfate) and 2-butanoyl-3,6,8-trihydroxy-1,4-naphtoquinone 6-O-sulfate, respectively, by chemical and spectroscopic analysis. Ptilometric acid 6-O-sulfate (1) showed an antifeedant activity on fish.
研究了脊索动物中的醌色素。分别从 Tropiometra afra macrodiscus 和 Oxycomanthus japonicus 中分离出了新的醌硫酸盐 1 和 3。通过化学和光谱分析,确定 1 和 3 的结构分别为 1,6,8-三羟基-3-丙基蒽醌-2-羧酸 6-O-硫酸盐(ptilometric acid 6-O-sulfate)和 2-丁酰基-3,6,8-三羟基-1,4-萘醌 6-O-硫酸盐。Ptilometric acid 6-O-sulfate (1) 对鱼类具有抗食源性活性。
