The purpose of the present study was to identify, by gas chromatography (GC) and GC-mass spectrometry (GC-MS), the components of the spontaneously emitted volatile organic compounds (VOCs), obtained by Solid-Phase-Micro-Extraction (SPME) and that of the hydrodistilled oil of the fresh flowers and leaves of Ononis natrix, as well as to compare them. The hydrodistilled leaf oil was rich in non-terpenoid aldehydes, whereas its aroma profile contained mainly sesquiterpene hydrocarbons with α-copaene and germacrene D as their major components. The hydrodistilled oil of the fresh flowers, however, revealed nearly equal amounts of terpenoid and non-terpenoid compounds; 51.00% and 46.54%, respectively. The aroma profile of the fresh flowers was dominated by monoterpene hydrocarbons with α-pinene (42.96%) and α-thujene (20.17%) as the predomi¬nant two monoterpenes. Based on the high total phenol and flavonoid contents of the water and ethanol extracts, LC-MS analysis was carried out to identify the major compounds from each sample. From the water extract, eleven compounds were identified, whereas the ethanol extract contained eight, whereby luteolin (from the water extract) and apigenin (from the ethanol one) were named as the major flavonoids, respectively.

Terpenoid Aldehydes

Hemigossypol (HG) and 6-methoxyhemigossypol (MHG) were the major terpenoid aldehydes isolated from stem stele tissue of 6-week-old verticillium-wilt-susceptible Rowden and verticillium-wilt-resistant Seabrook Sea Island 12B2 (SBSI) cotton plants infected for 14 days with Verticillium dahliae. HG constituted 90 and 45 mol % and MHG 6 and 41 mol % of the induced terpenoid in the steles of Rowden and SBSI, respectively. No terpenoids were detected in extracts of noninfected steles.The cellular localization of terpenoids in infected and noninfected stems was studied histochemically with a SbCl3 reagent. Terpenoids first occurred in both SBSI and Rowden in scattered, usually solitary, paratracheal parenchyma cells appressed to infected xylem vessels. After extensive fungal colonization, diffusion of induced terpenoids obscured the initial, discrete sites of localization.
