Plant growth inhibitory alkaloids were isolated from the extract of mesquite [Prosopis juliflora (Sw.) DC.] leaves. Their chemical structures were established by ESI-MS, 1 H and 13 C NMR spectra analysis. The I 50 value (concentration required for 50% inhibition of control) for root growth of cress (Lepidium sativum L.) seedlings was 400 μM for 3 -oxo-juliprosopine,...
The structure–activity relationships of alkaloids (1–5) from mesquite were subjected to assessment of growth inhibition against the shoot and root growth of monocotyledonous plants, barnyard grass, rice and timothy, and dicotyledonous ones, amaranth, lettuce and cress. All alkaloids tested generally showed growth inhibitory against both monocotyledonous and dicotyledonous plants. Furthermore, these...
