Fatty acid composition of leaf lipids of some Alchemilla L. (Rosaceae) species from Northeast Anatolia (Turkey)

Abstract

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, C 16:0, C 18:0, C 20:0, C 22:0, C 24:0, C 26:0 and C 28:0 as saturated, and C 16:1, C 18:1, C 18:2 and C 18:3 as unsaturated with the major fatty acids C 18:2 and C 18:3. The highest content of fatty acid was quantified in A. hirtipedicellata (78.34%) for ser. Elatae, A. erytropoda (68.74 %) for ser. Pubescentes, A. rizensis (76.47%) for ser. Sericeae, A. dura (73.94%) for ser. Calycinae and A. psedocartalinica (74.58%) for ser. Vulgares. The C 18:1 acid was determined in trace amounts while C 20:0, C 22:0, C 24:0 and C 28:0 acids were not determined in most of these species. Taxonomic value and phylogenetic implications of results are discussed.
