 "The chemical constituents of the essential oil Pelargonium graveolens leaves were analyzed by GC and GC-MS. Thirty compounds accounting for 99.1% of the oil were identified. The main components identified were citronellol (33.6%), geraniol (26.8%), linalool (10.5%), citronellyl formate (9.7%) and p-menthone (6.0%)." \\

+"Dimethylamylamine (DMAA) known as ‘methylhexanamine’ or ‘methylhexaneamine’ is a sympathomimetic component found in sports supplements (Monakhova et al., 2014). The trade name ‘Geranamine’ refers to geranium oil claimed as natural source of DMAA (Ping, Jun, Qing, 1996), however studies to date are unable to confirm DMAA presence in geranium oil (Austin, Travis, Pace, Lieberman, 2014)." \\
