Volatile constituents of leaves and stem of Justicia secunda Vahl have been investigated. The respective plant parts were extracted using hydrodistillation techniques and the volatile constituents were quantitatively analysed with Gas chromatography coupled to a mass spectrophotometer (GCMS). The results deduced from the spectra of the plant stem and leaf indicated the presence of twenty-four volatile compounds consisting of two (2) monoterpenoids, four (4) sesquiterpenes, one (1) sesquiterpenoid and seventeen (17) non-terpenoids. The isolated compounds and their concentrations were diethyl phthalate (28.71%), bis(2-ethylhexyl) phthalate (52.52%), (3aR, 4R, 7R)- 1,4,9,9-tetramethyl -3,4,5,6,7,8-hexahydro-2H-3a,7-methanoazulen-2-one (6.71%), 13-methyl-Z-14-nonacosene (1.08), 5(1H)-azulenone (34.67%), guaia-1(10), 11-diene (9.54%), γ-elemene (6.59%), 11-octadecenoic acid methyl ester (5.97%), hexadecanoic acid methyl ester (5.95%), trans-13-octadecenoic acid (5.01%), 1-ethoxy-2,2-dimethyl-3-(2-phenyl ethynyl)-cyclopropane (4.10%),  9(1H)-phenanthrone (3.28%), longifolene (2.93%), 2-hydroxycyclopentadecanone (2.92%), patchoulene (2.59%), 9-octadecenoic acid methyl ester (1.72%), oleic acid (1.26%) and 2-octylcyclopropaneoctanal (1.10%). The present study indicates that the stem and leaf of J. secunda Vahl is rich in volatile compounds that can provide useful medicinal or other industrial purposes.
