VITAMIN C AND CHLOROPHYLL
Several years ago it was pointed out1 that there is in general a parallelism between the distribution of vitamin C and that of chlorophyll and perhaps other plant pigments. The green portions of plants were especially excellent sources of cevitamic (ascorbic) acid. Recently2 a further study of this relationship has been made. Guinea-pigs fed a basal scurvy-producing ration were given as a supplement either the green leaves, the colorless leaves or the roots of certain plants, including carrot, turnip, endive, lettuce, onion and beet. The effect of the various supplements on the body weight, the appearance of hemorrhages at the joints, loosening of teeth, hemoglobin and erythrocyte content of the blood, and the cevitamic acid content of certain organs at necropsy was determined. In addition, the cevitamic acid content of the supplements was determined chemically by titration with 2-6-dichlorophenol-indophenol. In every instance the vitamin
