The proximate analyses and levels of carotenoids and minerals in the leaves of Amaranthus viridis L. and A. caudatus L. were measured. A. viridis leaves were composed of 32.2 % crude protein, 11.2 % fibre, 3.68 % fat, 18.7 % ash and a gross energy of 4.19 kcal/g, while in A. caudatus the crude protein content was 27.2 %, fibre 11.1 %, fat 5.40 %, ash 20.1 % and a gross energy of 4.66 kcal/g, all on a dry matter basis. The A. viridis leaves were superior to those of A. caudatus in the chlorophylls and carotenes contents and vitamin A potency. There were very high P concentrations in both leaves, with the value in A. viridis about 18 % higher than in A. caudatus. Na level in A. caudatus was low and there was a particularly high K concentration. These results compare favourably with those reported in many edible tropical leaf vegetables
