Chemical composition of essential oil of Psidium cattleianum var. lucidum (Myrtaceae)

AFRICAN JOURNAL OF BIOTECHNOLOGY, 2012
The aim of this study was to investigate the essential oil composition of Psidium cattleianum var. lucidum from South Africa. The essential oils were extracted by hydrodistillation and the components were identified by gas chromatography coupled to mass spectrometry (GC-MS) to determine the chemical composition of the essential oil.
