Abstract
Under the experimental conditions, fresh carrot root was found to be a much richer source of vitamin A activity than hitherto supposed. Daily doses of 100 mgm. of the fresh root sufficed to cure xer-ophthalmia and restore good growth in rats deprived of vitamin A. Under similar conditions a sample of carrot fat, from which much of the carotene had been removed, was found to be active in a dose of 0.4 mgm. daily. Carotene (M.P. 174[degree] in air) was found, even after many recrystallizations, to be. active in doses of 0.01 mgm. A possible explanation of the divergent results of other workers is put forward.This publication has 9 references indexed in Scilit:
