Fatty acid composition of total leaf lipids of 23 species from five series of the genus Alchemilla L. was studied by GC. Fatty acids identified and quantified are C 12:0, C 14:0, G 16:0, G 18:0, G 20:0, G 22:0, G 24:0, G 26:0 and G 28:0 as saturated, and G 16:1, G 18:1, G 18:2 and G 18:3 as unsaturated with the major fatty acids G 18:2 and G 18:3. The highest content of fatty acid was quantified in A. hirtipedicellata (78.34%) for ser. Elatae, A. A.erytropoda (68.74 %) for ser. Pubescentes, A. rizensis (76.47%) for ser. Sericeae, A. dura (73.94%) for ser. Galycinae and A. psedocartalinica (74.58%) for ser. Vulgares. The G 18:1 acid was determined in trace amounts while G 20:0, G 22:0, G 24:0 and G 28:0 acids were not determined in most of these species. Taxonomic value and phylogenetic implications of results are discussed.
