Eggplants ( Solanum spp.) are important vegetable crops, well known for nutritional and medicinal values of their fruits and leaves. In order to select more nutritious varieties in Ghana, 33 eggplant accessions were investigated for nutritional, mineral and antioxidant content of their fruits. Proximate and antioxidant analysis were determined by AOAC and DPPH methods. The results showed significant differences (P1.5 contributed 68.68% of total variability. Dry matter, protein, moisture and carbohydrate contents showed maximum contributions to the total variability. Biplot analysis displayed strong and positive associations among ash, protein and moisture with dry matter; moisture and carbohydrate and; protein and ash. Accessions San 005-01, San 005-02, SA 002-07, SA 002-08 and ST004-03 were identified as good sources of nutrients, minerals and antioxidant properties among the others; and could be used as potential donors for hybridisation programme to develop varieties with higher concentration of these traits. Les aubergines ( Solanum spp.) Sont des cultures légumières importantes, bien connues pour les valeurs nutritionnelles et médicinales de leurs fruits et de leurs feuilles. Pour sélectionner des variétés plus nutritives au Ghana, 33 accessions d'aubergines ont été étudiées pour déterminer la teneur nutritionnelle, minérale et antioxydante de leurs fruits. Les analyses proximale et antioxydante ont été déterminées par les méthodes AOAC et DPPH. Les résultats ont montré des différences significatives (P
