Oil and protein percentages, ash, iodine value, fatty acid and sterol compositions were studied in 28 Arachis hypogaea L. cultivars originating from Ecuador. Results showed lower protein percentages in the varieties hypogaea (27.3%) and hirsuta (25.9%) than in the varieties fastigiata (29.4%), peruviana (29.4%), and aequatoriana (31.3%). The principal fatty acids were linoleic and oleic. The variety hypogaea exhibited higher concentrations of oleic acid (45.1%). The sterol composition showed higher concentration of -sitosterol following by campesterol, stigmasterol, and 5-avenasterol.
