摘要

大量的Engraulis ringens（秘鲁凤尾鱼）与单尾目Pleuroncodes monodon（munida）一起被捕获，其潜在的生物活性脂质尚未被商业利用。在本研究中，从用己烷提取的munida脂质中获得了含有类胡萝卜素色素（虾青素）和必需脂肪酸（EPA+DHA）的脂质：异丙醇（He-I）、丙酮（Ac）、乙醇（Et）和超临界CO2+乙醇（SC-CO2-Et）。通过动脉粥样硬化指数（AI）、血栓形成指数（TI）和低胆固醇血症与高胆固醇血症（H:H）的比值来测定脂肪酸的功能质量。最高的虾青素（ASTX）含量（4238.65和4086.71µg/g脂质）对应于使用Ac和SC-CO2-Et的提取。EPA+DHA的含量范围为31.15%-31.85%，功能质量范围为0.56-0.61（AI）、0.19-0.21（TI）和1.73-1.81（H:H）。因此，SC-CO2-Et提取是可取的，因为其对环境的影响较小。IA和IT质量指数表明，食用munida脂质是健康的，尽管H:H比例显示相反。

Extraction of bioactive lipids from Pleuroncodes monodon using organic solvents and supercritical CO2

A huge volume of Engraulis ringens (Peruvian anchoveta) is caught together with the species Pleuroncodes monodon (munida), whose potential bioactive lipids are not commercially exploited. In the present study, lipid with carotenoid pigment (astaxanthin) and essential fatty acids (EPA+DHA) were obtained from munida lipids extracted with hexane:isopropyl alcohol (He-I), acetone (Ac), ethanol (Et) and supercritical CO2 + ethanol (SC-CO2-Et). The functional quality of the fatty acids was determined by atherogenicity index (AI), thrombogenicity index (TI) and the hypocholesterolemia:hypercholesterolemia (H:H) ratio. The highest astaxanthin (ASTX) contents (4238.65 and 4086.71 µg/g lipid) corresponded to extractions using Ac and SC-CO2-Et. EPA+DHA ranged from 31.15 to 31.85% and the functional quality ranges were between 0.56-0.61 (AI), 0.19-0.21 (TI) and 1.73-1.81 (H:H). Consequently, SC-CO2-Et extraction would be advisable because of its low environmental impact. The IA and IT quality indexes suggest that the consumption of munida lipids would be healthy, although the H:H ratio shows the opposite.
