    Author: Arima HK, Rodríguez-Amaya DB.
    Journal: Arch Latinoam Nutr; 1990 Jun; 40(2):284-92. PubMed ID: 2133187.
    Abstract:
    The carotenoid composition of a squash and a pumpkin from Northeastern Brazil was determined. Nineteen carotenoids were detected in Cucurbita moschata variety "Baianinha"; beta-carotene was the principal carotenoid, contributing about 74% of an average total carotenoid content of 317.8 micrograms/g. In C. maxima variety "Jerimum Caboclo", 11 carotenoids were found with lutein, and beta-carotene as the major pigments accounting for about 60% and 27%, respectively, of an average total carotenoid content of 78.4 micrograms/g. The abundance of beta-carotene in the C. moschata variety "Baianinha" makes this squash one of the richest sources of provitamin A. The average vitamin A value was 43,175 IU (International Units) per 100 g or 4,317 RE (retinol equivalents) per 100 g. Its vitamin A values is more than 11 times that of C. maxima variety "Jerimum Caboclo" and five times that of C. moschata cultivar "Menina Verde", the squash found previously to be highest in provitamin A among the Cucurbita vegetables most commercialized in São Paulo (Southeastern Brazil).
