説明
A novel bitter amino acid, pulcherrimine was analyzed by reverse-phase high-performance liquid chromatography using a linear gradient elution consisting of methanol/aqueous/acetic acid and methanol/acetic acid mixture, after being labeled with dimethylaminoazobenzenesulfonyl chloride (Dabs-Cl). Linearity of the calibration curve for pulcherrimine was high (r=0.994) in the tested range from 0 to 4 μg/mL. By this method, the pulcherrimine content in the ovary and testis of the green sea urchin Hemicentrotus pulcherrimus, collected in the sea off Iwaki in November 1998, was analyzed. The mean pulcherrimine content in the ovary was 1.37 mg/100 g. In contrast, no pulcherrimine was detected in all testes examined. Correlation between the bitterness and the pulcherrimine content was statistically significant. These results strongly support that pulcherrimine is a bitter principle in the green sea urchin ovaries.
