The fatty acids composition of leaf, stem and fruit of Medicago noeana, M. orbicularis, M. polymorpha var. vulgaris, M. rigidula var. submitis and M. rigidula var. rigidula were analyzed by gas chromatography-mass spectrometry. The analysis fatty acid composition of all the organs of these species revealed that palmitic (C16: 0), stearic (C18: 0), oleic (C18: 1), linoleic (C18: 2) and linolenic acids (C18: 3) were major fatty acids. In addition, lauric (C12: 0), myristic (C14: 0), pentadecanoic (C15: 0), heptadecanoic (C17: 0), palmitoleic (C16: 1), arachidic (C20: 0) behenic (C22: 0) and lignoseric acids (C24: 0) were also found in some species. There was fluctuation in fatty acid levels of different organs. Linolenic acid found in all species, especially at the highest level in leaves. Oleic acid was noted at higher level in fruits of all the species
