The predominant carotenoids in extracts of female and hermaphrodite Papaya fruits ( Carica papaya L) Solo cv Sunrise were determined by high‐performance liquid chromatography on a C 18 reversed‐phase column using a diode‐array detector. Three classes of carotenoids were separated and identified from the papaya extract without saponification; these were xanthophylls, hydrocarbon carotenoids and carotenol fatty acid esters. The xanthophylls were identified as trans ‐zeaxanthin, cryptoflavin and β‐cryptoxanthin; other xanthophyls were detected in very small quantities. The major hydrocarbon carotenoid was identified as lycopene. Carotenol fatty acid esters were identified as carotenol fatty acid esters of β‐cryptoxanthin, cryptoxanthin‐5,6‐epoxide, lutein, zeaxanthin and violaxanthin. There were no qualitative differences among the carotenoid pattern of female and hermaphrodite papaya fruits. Changes in carotenoid composition during ripening in hermaphrodite and female papaya fruits (cv Sunrise) were investigated in three different stages of ripeness. These changes could be shown in terms of Hunter colour values.
