This is the first report of pectenolone and pectenoxanthin, two types of carotenoid, in the muscle of the Yesso scallop.3 Roles of the carotenoids composition and accumulation in Yesso scallopThe method for detecting carotenoids using reverse phase high performance liquid chromatography was developed. The conditions of RP-HPLC analysis were an analytical scale (200×4.6 mm, inner diameter 5μm) Eclipse XDB-C18 column of Agilent corporation; 10μl injection volume; 25°C column temperature; acetonitrile, methanol and methylene dichloride mobile phase (40:56:4, V/VV) with 0.1% BHT; 1.0 ml per minute flow rate; 450 nm UV-VIS detector; 8 minutes elution.The carotenoids from orange muscle of Yesso scallop of 7, 10, 12, 15, 18, 22 months old was detected using the method refered above.

通过柱层析、高效液相等手段对橘红色闭壳肌中的主要类胡萝卜素进行了提取分离，分离提纯得到两种类胡萝卜素，并通过MS、~1H-NMR和~(13)C-NMR对其进行结构鉴定，结果表明(3S，3\'R)-3，3\'-dihydroxy-7\'，8\'-didehydro-β，β-Caroten-4-one和(3S，3\'S)-7，7\'，8，8\'-tetradehydro-β，β-Carotene-3，3\'-diol，俗称pectenolone和pectenoxanthin是橘红色闭壳肌中的主要类胡萝卜素，这是国内外首次对虾夷扇贝闭壳肌中的类胡萝卜素进行提纯及结构鉴定。3虾夷扇贝类胡萝卜素的种类组成和累积变化规律建立了橘红色闭壳肌中类胡萝卜素的HPLC分析定量检测技术：色普柱为Agilent公司的Eclipse XDB-C18柱200mm×4.6mm，i.d.5μm进样体积，5μl ；流速1ml/min；检测波长450nm；柱温25℃；流动相为乙腈：甲醇：二氯甲烷(V/V/V=40：56：4并加入0.1%的BHT；分离时间为8min。
