使用高效液相色谱 (HPLC) 结合电喷雾电离质谱法对红藻江蓠（日本流行的海藻之一）中的花生四烯酸代谢物类二十烷酸进行了鉴定。前列腺素 (PG) E-2、19-酮-PGE(2) 和 8-羟基二十碳四烯酸 (HETE) 被检测为主要类二十烷酸，PGA(2)、白三烯 B-4 为次要类二十烷酸。 8-和12-HETE在HPLC分析中具有相同的保留时间，但使用这种分析方法，我们能够识别它们。 (C) 1998 Elsevier Science B.V.
Identification of eicosanoids which are metabolites of arachidonic acid in red algae Gracilaria asiatica, one of the popular seaweeds in Japan, was carried out using high-performance liquid chromatography (HPLC) interfaced with electrospray ionization mass spectrometry. Prostaglandin (PG) E-2, 19-keto-PGE(2), and 8-hydroxyeicosatetraenoic acid (HETE) were detected as major eicosanoids and PGA(2), leukotriene B-4 as minor ones in G. asiatica. 8- and 12-HETE had the same retention time in HPLC analysis, but using this analytical method, we were able to identify them.
