volatile components of three parts of pimpinella tragium vill. (umbelliferae family) from iran were investigated qualitatively and quantitatively for the first time. essential oils were isolated by hydro-distillation from stems plus leaves, inflorescence and seeds of p. tragium individually. the plant materials were collected from polour (northeast of tehran province). the yields of the stems p...

      The chemical composition of the essential oil obtained from the aerial parts of Laurus nobilis L. has been examined by gas chromatography (GC) and GC- mass spectrometery (MS). The main components of the oil were identified. 1,8-Cineole was the major component in the oil together with b-terpinyl acetate, terpinene-4-ol, a-pinene, b-pinene, p-cymene, linalool and ...
