A subcellular fraction with a high share of carotenoids (about 150 mkg/mg of protein) was obtained from the nerve tissue of Lymnaea stagnalis, the fractionation being made by sucrose density gradient centrifugation. The quantity of carotenoids extracted from fractions was estimated spectrophotometrically. The electron microscope observations demonstrated the presence of structures analogous to fraction components in the mollusc neurones and similar to some kinds of plant chromplasts (carotenoidplasts).
从椎实螺的神经组织中获得了一个类胡萝卜素含量很高（约150微克/毫克蛋白质）的亚细胞组分，该组分通过蔗糖密度梯度离心法进行分离。通过分光光度法估算从各组分中提取的类胡萝卜素的量。电子显微镜观察表明，在软体动物神经元中存在类似于组分成分的结构，并且与某些种类的植物色素体（类胡萝卜素质体）相似。
