Fig. 1From: Induction of programmed cell death in Trypanosoma cruzi by Lippia alba essential oils and their major and synergistic terpenes (citral, limonene and caryophyllene oxide)Typical gas chromatography-mass spectrometry (GC-MS) profiles, in a DB-5 (60Â m) column with a mass selective detector (EI. 70Â eV), of essential oils obtained from Lippia alba Carvone (a) and Citral (b) chemotypes by microwave-assisted hydrodistillation (MWHD). The corresponding peak identification is showed in Table 2Back to article page
