This study was carried out upon chemical
researches of three species Crocus L. that distribute in Central
Anatolia (Eskişehir), Turkey. The volatile compounds were obtained by
microdistillation of the stylus, stigma-tepal parts of three critically endangered and endemic
species of the genus Crocus L., viz. C. chrysanthus (Herb.) Herb., C. antalyensis B. Mathew and C. ancyrensis (Herb.) Maw, and the stylus, stigma parts of C.
sativus L. and the volatiles were analyzed by GC and GC-MS,
simultaneously. Ethyl cinnamate (14.8%), heptanal (14%), and hexahydrofarnesyl acetone (12.8%) were
detected as main constituents in sample of C.
chrysanthus. Hexanal (17.7%), nonanal (17.1%), and undecanal (14.7%) were
found as main constituents in sample of C.
antalyensis. β-Isophorone (14.4%), heptanal (11.5%), and heneicosane (8.5%)
were found as main constituents in sample of C. ancyrensis. Safranal (77.9%), α-isophorone (13.5%), and
β-isophorone (2.2%) were detected as main constituents in sample of C. sativus. In addition, chemical structures of C.
ancyrensis, C. chrysanthus and C. antalyensis are given in this study for the first time.
