✦ Synopsis

Seeds of 11 sorghum cultivars (Sorghum bicolor) from Argentina were analysed for proximate composition, fatty acids and sterols. Oil, protein, carbohydrate and ash contents varied between 41 and 66 g kg-', 111 and 156 g kg-', 670 and 730 g kg-' and 13-8 and 20.6 g kg-' of dry matter, respectively. Fatty acid profiles revealed that the major acids were palmitic (15.1-24.8%), oleic (29.9-41.8%) and linoleic (35.9-51.3Yo). Unsaponifiable matter was examined for sterols. Sitosterol was the prominent component in all cultivars (434-57.9%), followed by campesterol(18.7-29.1%) and stigmasterol (12.4-20.5?40).
