1. Carotenoid pigments of Chlorella and Scenedesmus.The distribution and the content of carotenoids in Chlorella vulgaris and Scenedesmus obliquus were investigated. The pigments were separated by solvent distribution and chromatography on Ca(OH): and identified by their absorption spectra and color reaction. The main carotenoids were α-carotene, 5%; β-carotene, 15%; neo-β-carotene u, 3%; lutein, 63%, and violaxanthin, 4%; and the percentage of the total carotenoids in these pigments was 95%.The content of α-carotene and β-carotene in raw Chlorella was about 20mg% and 70mg% and in dried Chlorella was about 3mg% and 10mg% respectively.2. The absorption test of carotene of Scenedesmus on weanling rats.Weanling rats weighing from 60 to 70g. were used for the absorption test of carotene of Scenedesmus, and after one week feeding on the vitamin A-free diets, they were fed the diets containing 20% of dried Scenedesmus.Ingested carotene and excreated carotene of each rats were measured every day from 3rd day to 5th day in the experimental period.From the results of the experiment, the average rate of absorption of α-carotene and β-carotene of Scenedesmus was 41 and 22% respectively.
