Plant Growth Inhibitor from Abrus precatorius Seeds

Plant Growth Inhibitor from Abrus precatorius Seeds.

Polysaccharide structure of degraded glucomannan from Abrus precatorius Linn. seeds.

Degraded glucomannan was isolated from Abrus precatorius Linn. seed polysaccharide (Papilionaceae). Acid hydrolysis and methylation studies produced certain degraded methyl sugars as, 2, 3, 6-tri-O-methyl-D-glucose and 2, 3, 6-tri-O-methyl-D-mannose in 1:4 molar ratio. On the basis of hydrolysis and methylation experiments, a polysaccharide structure has been assigned to the degraded glucomanna...

Antitrypanosomal isoflavan quinones from Abrus precatorius.

Human African trypanosomiasis is a neglected tropical disease in sub Saharan Africa that is fatal if left untreated. In a search for new natural products with antitrypanosomal activity, we recently identified abruquinones B and I from Abrus precatorius as potent in vitro trypanocidal compounds with high selectivity indices. To obtain sufficient compound for in vivo efficacy tests in mice, a sec...
