Lignin and polyphenols as allelochemicals
Industrial Crops and Products, 2008By the microbiological action, lignin from vegetal wastes is transformed at soil level in organic prebiotic products with physiological activity on plants development. On the other hand, some micromolecular compounds resulted from plant wastes decomposition, along with polyphenols coming from extraction of plant residues could play a role of ...

Biological activity of allelochemicals
The field of therapeutic medicine and drug discovery is undergoing a renaissance, marked by a renewed interest in natural products as a source of novel pharmaceuticals. In the age of advanced synthetic chemistry and biotechnology, the vast potential of natural compounds often remains untapped, yet history has repeatedly shown that nature harbors a ...Kumar, Samit, Mishra, Pratima

Allelochemics as Systematic Markers
1982Life, as we know it, is inconceivable without hydrogen, carbon, nitrogen, oxygen, phosphorus, sulphur etc. The production of the heavier of these elements requires several billion years of “cooking” time in the interior of a star. The time lapse from the “Big Bang” to the final gravitational collapse of a universe, however, is, according to Einstein’s ...

Bioavailability of Allelochemicals in Soil
2008Abstract : The successful spread of the weeds Acroptilon repens (Russian knapweed, RK) and Centaurea maculosa (Spotted knapweed, SK) has been attributed to the exudation of allelopathic chemicals by their roots. RK releases 7,8-benzoflavone and SK releases (+/-)- catechin.

Evolution of Allelochemics in Angiospermae
1982Primitive angiosperms may owe their woody habit to a gymnosperm-type ancestry. Gymnosperms, in which, significantly, alkaloids are rare, possess the metabolic pathway sugar → shikimic acid → chorismic acid → phenylalanine → cinnamic acid → cinnamyl alcohol (Fig.
