对金鸡儿中的苯醌色素进行了研究。从非洲黄花和日本棘豆中分别分离得到新的苯二酚硫酸酯1和3。经化学和波谱分析确定其结构分别为1，6，8-trihydroxy-3-propylanthraquinone-2-carboxylic酸6-O-硫酸盐和2-丁酰基-3，6，8-三羟基-1，4-萘醌6-O-硫酸盐。6-O-硫酸酯(1)对鱼类有拒食活性。
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.
