The present study aimed to identify the content of astaxanthin and its esterified forms using high-performance liquid chromatography coupled with diode array and atmospheric pressure chemical ionisation mass spectrometry detection in three samples of shrimp waste. The analyses revealed twenty-one astaxanthin derivatives, including astaxanthin in free form, across all three extracts with the highest number of derivatives observed in the head extract. The shell extract had a lower content of astaxanthin and its esterified forms, with monoesterified astaxanthins being the major components, with contents ranging from 0.5-1 mg g. On the other hand, in both global waste and head extracts, astaxanthin diesters were found to be the dominant bioactive compounds, with contents ranging from 0.7-5.2 mg g and 10.2-18.2 mg g, respectively. Notably, the astaxanthin content extracted from head was significantly higher compared to other extracts, indicating its potential as a valuable source of bioactive compounds.
本研究旨在通过高效液相色谱-二极管阵列-大气压化学电离质谱联用检测三种虾废料样品，鉴定虾青素及其酯化形式的含量。分析表明，三种提取物中共发现二十一种虾青素衍生物，包括游离虾青素，其中头部提取物中观察到的衍生物数量最多。壳提取物中虾青素及其酯化形式的含量较低，以单酯化虾青素为主，含量在 0.5-1mg/g 之间。另一方面，在全球废物和头部提取物中，虾青素二酯被发现是主要的生物活性化合物，含量分别在 0.7-5.2mg/g 和 10.2-18.2mg/g 之间。值得注意的是，从头部提取的虾青素含量明显高于其他提取物，表明其作为生物活性化合物有价值的来源的潜力。
