Extract

It has been shown that extracts of various weeds and crop plants inhibit germination and seedling growth (1, 4, 5, 7). In early experiments (7) it appeared that extracts of leafy spurge (Euphorbia esula) were particularly effective. For this reason it was of interest to more fully characterize the composition of leafy spurge. The present communication summarizes the results of qualitative paper chromatographic determinations for amino acids and sugars.
