Stenocereus stellatus fruits from Puebla, Mexico, with red, purple, yellow, and white pulp were characterized regarding their total betalain content, and physicochemical properties. The total betalain content was 856.07-2968 mu g per gram of pulp dry weight. Using principal component analysis, the levels of pigments in S. stellatus fruits were compared with 32 samples from other cactus fruits. As a result, three confidence intervals for total betalain content (g g(-1)) were calculated: low (<1208), medium (2935-3288), and high (4488-9248). Thus, the cactus fruits can be categorized as a poor, good, and excellent source of betalain pigments.
