The Ferula genus is a very rich source of sesquiterpene coumarins. The chemical constituents derived from Ferula spp (aerial parts and roots) have been extensively investigated by a few research groups, notably, more than 200 compounds consisting of essential oils, coumarins, phenylpropanoid derivative and steroidal compounds have been identified [1]. Studies on the chemical constituents of this genus have developed rapidly over the last 20 years and around 130 different sesquiterpene coumarins have been reported from this genus [2]. Materials and methods: The methods used in the process of investigation on the qualitative analysis as well as separation include thin layer chromatography (TLC), silica gel column chromatography (silica gel: 200-300 mesh, Qingdao Marine Chemical Company, China), sephadex LH-20 column chromatography (LH-20 gel: Amersham Pharmacia Biotech, Sweden), and HPLC with a ODS-A (50 µm) column produced by YMC Co.Ltd (Japan). 1H NMR, 13C NMR, and 2D NMR spectra were recorded onVarian MR-400, VNMRS-600 NMR spectrometers with TMS as an internal standard. Experimental part. The dry aerial parts of Ferula feruloides (4 kg) were powdered and extracted with 70% EtOH six times at room temperature and concentrated under reduced pressure to give 340 g of residue. The concentrates were reconstituted with distilled water in a ratio of 1:1 (concentrate: distilled water), then it was extracted successively with different organic solvent with increasing polarity such as petroleum ether (36.0 g), chloroform (44.0 g), ethyl acetate (17.0 g) and n-BuOH (21.0 g).
