Abstract

In a “dehesa” of Castilla–La Mancha (CIA “El Dehesón del Encinar”, Oropesa, Toledo) grasssamples were collected during the period October-December. Fatty acids more abundant in theautumn grass were linolenic (C18:3 n-3), palmitic (C16:0), linoleic (C18:2 n-6) and oleic (C18:1 n-9). Average proportions of such fatty acids were 54.96, 21.15, 13.97 and 3.05% respectively.Plot and month had not significant effect on the proportions of such fatty acids. Correlationcoefficients obtained between the C18:3 n-3 proportion and the remaining fatty acids of grasswere negative and significant (P <0.05). Grass average contents in alpha and gamma tocopherolwere 276.81 and 11.22 mg/kg DM respectively. Plot had not significant influence on gammatocopherolcontent.
