AB  - The Vlasina plateau shows significant floristic diversity counting 956 species of which 91 may be categorized as endangered
in the flora of Serbia. The genus Geranium is present in the
flora of this region with few species and they are the subject
of our research. The chemical composition of volatile compounds of aerial and underground parts of eight Geranium L.
species (G. macrorrhizum L., G. phaeum L., G. sanguineum L.,
G. robertianum L., G. palustre L., G. pyrenaicum Burm. f., G.
columbinum L. and G. lucidum L.) collected in flowering stage
from Vlasina plateau (Serbia) was examined. The samples of
volatile fraction were obtained by steam distillation and analyzed using GC-FID and GC-MS. The cluster analysis revealed
the separation of volatile compounds of Geranium species to
two clusters. The aerial and underground parts volatiles of G.
macrorrhizum were separated from the other species, based
on the high sequiterpenes content (92.3% and 94.6%), mostly
germacrone (73.3%) in the aerial and δ-guaiene (76.8%) in
the underground parts. The volatile fractions of other species
were mainly composed of sesquiterpenes (10.8-61.8%), diterpenes (12.9-43.0%) and fatty acids and their derivatives (6.6-
21.6%). The exception was the fraction of the underground
parts of G. phaeum which was predominantly made by fatty
acids and their derivatives (76.6%). In the volatile fraction of
G. palustre aerial parts β-selinene (18.6%) and (E)-caryophyllene (15.7%) prevailed. Hexadecanoic acid (15.4%), germacrene D (15.4%), (E)-caryophyllene (10.6%), phytol (10.4%)
and caryophyllene oxide (10.2%) were the most abundant
compounds in volatile fraction of G. pyrenaicum aerial parts,
while phytol (13.2%) and (E)-caryophyllene (9.5%) in the volatile fraction of G. lucidum aerial parts. Hexadecanoic acid
and phytol were dominant compounds in the volatile fraction
of aerial parts of G. sanguineum (21.1% and 17.8%), G. robertianum (12.5% and 19.3%), G. phaeum (7.3% and 41.4%) and
G. columbinum (14.5% and 29.5%). Volatiles of aerial parts of
G. robertianum were also characterized by (E)-caryophylene
(8.0%) and caryophyllene oxide (7.4%), while the volatiles of
G. sanguineum contained β-bisabolene (5.2%). The volatiles
of G. palustre aerial parts have been studied for the first time.
The chemical characterization of volatile compounds of Geranium species may possibly have chemotaxonomic importance
and is significant for further research of Vlasina plateau native
flora.
