Popis:	Essential oils were obtained by hydro distillation from aerial, seed and root parts of Asystasia gangetica (L) and analyzed for their constituents by gas chromatography (GC) and gas chromatography coupled with mass spectrometry (GC-MS). Fifty-four compounds were identified in aerial, twenty-one in seed, fifteen in root, respectively which are responsible for 96.80 %, 65.11 % and 78.50 % of oil in each. Aerial is dominated by phthalates (39.00 %), cycloalkanes (28.23 %) and aromatics (17.14 %); the most abundant compounds are toluene (9.12 %), methylcyclohexane (9.02 %) and bis-isodecyloctylphthalate (6.05 %). Others in aerial are branched (6.13 %) and straight chain (3.24 %) alkanes, esters (1.71 %), alcohol (0.72 %), acid (0.36 %), hetero compound (0.27 %), ketone (0.18 %) and terpenoid (0.09 %). Phthalates (24.67 %), alcohols (16.28 %) and straight chain alkanes (8.56 %) are the largest groups in seed oil, with dinonylphthalate (9.40 %), 1-octenol (8.05 %) and methylcyclohexane (6.04 %) as most...
