The biochemical properties of carotenoids from 2 species of freshwater bivalve, namely, Unio douglasiae nipponensis and Anodonta lauta, and 2 species of freshwater snail, namely, Cipangopaludina chinensis laeta and Semisulcospira libertina, were investigated. Diatoxanthin and fucoxanthin were identified as major carotenoids in both bivalves. In contrast, lutein and zeaxanthin were found to be the major carotenoids in C. chinensis laeta. In addition, a series of keto carotenoids was also identified in S. libertina.
对两种淡水双壳贝类，即日本背角无齿蚌和椭圆背角无齿蚌，以及两种淡水螺类，即中国圆田螺和放逸短沟蜷中的类胡萝卜素的生化特性进行了研究。在这两种双壳贝类中，二羟基玉米黄质和岩藻黄质被鉴定为主要类胡萝卜素。相比之下，叶黄素和玉米黄质被发现是中国圆田螺中的主要类胡萝卜素。此外，在放逸短沟蜷中还鉴定出了一系列酮类类胡萝卜素。
