Abstract :The chemical composition of different plant parts varies, both within the plant itself, as well as among different plants,  which is due to their s tructure, s tage of growth and phenological characteris tics. In this s tudy, the results of a research  conducted in 2013, in a subalpine ecosys tem in Epirus insert ignore into journalissuearticles values(Greece); are presented. The objectives of this research were the  determination of crude protein and total fat insert ignore into journalissuearticles values(ether extract); of the ecosys tem’s main grassland plants, per group insert ignore into journalissuearticles values(grasses,  legumes, other forbs);, at different s tages of growth. These plant species were: a); grasses insert ignore into journalissuearticles values(Alopecurus gerardil Vill, Stipa  pennata L., Phleum alpinum L.);, b); legumes insert ignore into journalissuearticles values(Trifolium repens L, Lathyrus aphaca L, Lotus corniculatus L.); and c); other  forbs insert ignore into journalissuearticles values(Ranunculus repens L., Achillea millefolium L. and Geranium lucidum L.);. The results showed that: a); the larges t  amount in crude protein was found in Trifolium repens L. with a percentage of 17.05%, with a s tatis tically significant  difference only with grasses, b); in all plant species, the larges t amounts of crude protein and total fat was observed during  the initial s tage of plant growth, showing a gradual decrease until the final s tage of growth, c); s tatis tically significant  differences appeared in the amount of crude protein and total fat, between the same plant species, at different sampling  dates, and between different plant species in the same sampling dates and d); the amount of total fat in all plant species  was on average 3%.
