The internal standard tridecane was added in terms of 50 [micro]g of the substance per a certain quantity of a plant sample.
In the present study, two different aliphatic hydrocarbons; hexane and tridecane, were identified.

Plant roots exudates influenced root-knot nematodes egg hatch, as root exudates of resistance tomato cultivars were known to produce higher amount of compounds associated with resistance, which included heptadecane, tridecane, tetradecane, hexadecane, pentadecane, hexatriacontane, hexadecane, 2,6,10,14-tetramethyl, octadecane, nonadecane, eicosane and heneicosane against Meloidogyne incognita(Yang et.
Among them the liquid alkanes (undecane dodecane tridecane tetradecane pentadecane hexadecane heptadecane etc.) are widely used in fuel oils and as anti-corrosive agents in lubricating oils and solid alkanes (octadecane nonadecane eicosane heneicosane tricosane tetracosane heptacosane octacosane etc.) find their use in paraffin waxes of different kinds.
From this analysis we found some hydrocarbon compounds like alkane and alkene group compound such as Tridecane ([C.sub.13][H.sub.28]) at retention time 13.41 minutes and compound peak intensity is lower than middle compounds.
africana contains tridecane, nonadecane, pentadecane, hexadecane, eicosene, nonadecene and pentadecene.
Different compounds were detected in different quantities from different sources compounds more than 10% were Toluene (63.515), Benzene1,3-dimethyl (12.589), Undecane (52.29) and Aniline, N-methyl (13.964), compounds from 1 to 10% were Ethylbenzene (2.771) and o-Xylene (3.097) whereas compounds less than 1% were Nonane (0.426), Nonane (0.168), 2-Propenoic acid (0.372), Undecane (0.082), Dodecane (0.074), Tridecane (0.077), Tetradecane (0.069), Pentadecane (0.045), Hexadecane (0.054) and Octadecane (0.031) detected in callus cultures under the influence of MBN2,3 medium.
Examples are undecane and tridecane. These compounds are found in the exocrine secretions of a variety of Hymenoptera, Heteroptera, and beetles, and they are considered weak trigeminal irritants (Alarie et al., 1998).
PM10 from urban Guaynabo, Puerto Rico, has been partially characterized to contain phthalates, malathion, 4-morpholinepropamine, 6-undecylamine, 1-[3-methyl-4-(4-morpholinyl)- l-oxo-2,2-diphenylbutyl]-pyridine, and tridecane (2).
Preliminary gas chromatography/mass spectrometry results for the extracts at the Guaynabo site show that some of the compounds mostly found there are: bis(2-ethylhexyl) phthalate; malathion; dibutyl phthalate; 4-morpholinepropanamine; 6-undecylamine; 1-[3-methyl-4-(4-morpholinyl)-1 -oxo-2,2-diphenylbutyl]-pyridine; and tridecane. Their concentrations range between 1 and 100 ng/[m.sup.3].
