Abstract
Abstract Alumina, activated as described, can be used in the chromato‐graphic analysis of the carotenoids of the mango fruit; it effects the separation of four distinct pigments in the fruit. Data for the varieties of fruit are recorded. As mangoes ripen the total carotenoid content and that of the individual pigments rise rapidly to a maximum and then fall later. At temperatures above normal (36° C., 40° C.) these changes are accelerated, but the maximum values are substantially unchanged. Exposure of fruit to ultra‐violet light appears to increase the total carotenoid content (including the maximum value) throughout the ripening period. After the work reported in this paper was completed similar data were published by Sadana and Ahmad 22a for other (Saroli, Desi and Chounsa) varieties of mangoes. They also have observed an increase in pigments, notably β‐carotene, during ripening.
