The investigation on phytochemicals from Ferulago angulata (Schlecht) Boiss, indigenous to central parts of Iran

Ferulago angulata (Schlecht) Boiss (Apiaceae) is a perennial herb distributed in the central parts of Iran. In this work, the essential oil of Ferulago angulata aerial parts collected from the central parts of Iran was obtained by using hydrodistillation analysed by GC and GC-MS. Air-dried and powdered plant roots were extracted with n-hexane, dichloromethane and methanol, respectively, using a Soxhlet apparatus. The n-hexane extract was subjected to preparative thin-layer chromatography using chloroform-acetone (95:5) as solvent system to yield two linear furanocoumarins, prantschimgin and oxypeucedanin. The structure of theisolated compounds was elucidated by using spectroscopic data such as H-1 NMR, C-13 NMR, UV and IR. The results of GC-MS analyses showed that gamma-terpinolene (11.97%), alpha-pinene (10.00%), sabinene (6.89%), linalool (5.56%) and cis-ocimene (4.41%) were the main components among 51 constituents characterised in the oil. The oil exhibits considerable phytotoxic activity.
