  ABSTRACT: The volatile constituents of the essential oil of Hymenocrater longiflorus Benth. growing wild in Kurdistan-Iran were investigated using the GC and GC/MS techniques. Fifteen compounds, representing twenty (97.03%) of the total oil were identified. The main components were: α- Pinene (22.47%), β-Caryophyllene (18.05%), β- Eudesmol (14.92%), α-Copaene (9.84%), γ-Elemene (6.79%), δ-Cadine-ne (6.13%), (–)Bornyl acetate (5.61%), α-Amorphene (3.84%), α-Fen- chyl acetate (2.35%) and β-Pinene (2.07%). Some of the physicochemical properties like the logarithm of calculated Octanol-Water partitioning coefficients (log Kow), total biodegradation and (TBd in mol/h and gr./h), water solubility (Sw, mg.L-1 at 25oC) and median lethal concentration 50 (LC50) were calculated for the 15 com- ponents of Hymenocrater longiflorus Benth.
