Abstract

The effect of water stress on the polyacetylenic constituents of carrots (Daucus carota L, cv ‘Orlando Gold’) was studied by liquid chromatographic analysis. Eleven polyacetylenes were isolated fiom plants grown in the greenhouse under normal conditions and under conditions simulating drought or waterlogging. Three compounds were identified. These include the known carrot polyacetylenes falcarinol (cis‐heptadeca‐1,9‐diene‐4,6‐diyn‐3‐ol), falcarindiol (cis‐heptadeca‐l,9‐diene‐4,6‐diyn‐3,8‐diol), and falcarindiol‐3‐monoacetate (cis‐3‐acetoxyheptadeca‐1,9‐diene‐4,6‐diyn‐8‐ol). Three of the eight unidentified compounds were produced only by one or both stressed samples. The other eight (including the three knowns) were less concentrated in the stressed samples than in the control.
