Leaves of Pueraria thunbergiana possess allelopathic activity and the putative compounds causing this growth inhibitory effect were isolated from their aqueous methanol extract. The chemical structures of these growth inhibitors were determined by high-resolution MS and 1 H NMR spectral data as cis,trans-xanthoxin and trans,trans-xanthoxin. cis,trans-Xanthoxin and trans,trans-xanthoxin inhibited...
The residue of peas (Pisum sativum L.) has allelopathic activity and the putative compound causing this inhibitory effect was isolated from a methanol extract of pea shoots. Chemical structure of this compound was determined by high-resolution MS, IR and 1 H NMR spectral data as pisatin. Pisatin inhibited growth of cress (Lepidium sativum L.) and lettuce (Lactuca sativa L.) seedlings at concentrations...
