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 β-sitosterol (554–632 g kg-1) following by campesterol (139–180 g kg-1), stigmasterol (82–130 g kg-1) and Δ5-avenasterol (86–138 g kg-1).
