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).
对来自巴西东北部的一种南瓜和一种西葫芦的类胡萝卜素成分进行了测定。在南瓜属品种“Baianinha”中检测到19种类胡萝卜素；β-胡萝卜素是主要的类胡萝卜素，在平均总类胡萝卜素含量317.8微克/克中约占74%。在南瓜属品种“Jerimum Caboclo”中，发现了11种类胡萝卜素，其中叶黄素和β-胡萝卜素为主要色素，分别占平均总类胡萝卜素含量78.4微克/克的约60%和27%。南瓜属品种“Baianinha”中β-胡萝卜素的丰富含量使其成为维生素A原最丰富的来源之一。其平均维生素A值为每100克43,1,75国际单位（IU）或每100克4,317视黄醇当量（RE）。其维生素A值是南瓜属品种“Jerimum Caboclo”的11倍多，是南瓜属品种“Menina Verde”的5倍，“Menina Verde”是此前在圣保罗（巴西东南部）最商业化的南瓜属蔬菜中维生素A原含量最高的西葫芦。
