Oil, protein, ash, carbohydrate, iodine value, fatty acid and sterol compositions were studied in 46 aboriginal Arachis hypogaea cultivars originating from Bolivia. The oil and protein contents varied between 440 and 547 g kg-1 and 242 and 547 g kg-1, respectively. Results showed a lower protein content in the variety hypogaea (264.4 g kg-1) than in the varieties fastigiata (299.7 g kg-1) and peruviana (294 g kg-1). The carbohydrate content ranged between 86 and 216 g kg-1. The principal fatty acids were oleic (358-536 g kg-1) and linoleic (250-462 g kg-1). The variety hypogaea exhibited higher concentrations of oleic acid (449.0 g kg-1). The sterol composition showed higher concentration of beta-sitosterol (554-632 g kg-1) following by campesterol (139-180 g kg-1), stigmasterol (82-130 g kg-1) and delta5-avenasterol (86-138 g kg-1).
