采用高效液相色谱-常压化学电离-质谱（HPLC-APCI-MS）分析了25种本土珊瑚甲醇提取物的类胡萝卜素成分。其中9种提取物在450 nm处均有可检出峰，紫外/可见光谱均具有类胡萝卜素特异性。类胡萝卜素峰的大量数据表明，在文献比较的基础上，只鉴定出了周内素，这表明可能存在新的类胡萝卜素结构。这是首次报道的对韩国本土珊瑚类胡萝卜素的调查，需要进一步的工作来探索类胡萝卜素及其在韩国本土珊瑚生态系统中的潜在作用。
In this study, methanol extracts from 25 indigenous Korean corals were prepared and their carotenoid constituents were analyzed by high-performance liquid chromatography-atmospheric pressure chemical ionization-mass spectrometry (HPLC-APCI-MS). Among them, extracts from nine species showed detectable peaks in the HPLC chromatogram at 450 nm and the ultraviolet/visible spectra exhibiting carotenoid-specific characteristics were chosen. The mass data of carotenoid peaks revealed that only peridinin could be identified based on literature comparison and suggested the potential presence of novel carotenoid structures. This is the first reported investigation of indigenous Korean coral carotenoids and further work is needed to explore the carotenoids and their potential roles in the ecosystem of indigenous Korean corals.
