Purification, properties, and crystallographic data for a principal nontoxic lectin from seeds of Abrus precatorius.

Plant Growth Inhibitor from Abrus precatorius Seeds.

Immunopotentiating activity of abrin, a lectin from Abrus precatorius Linn.

A non-toxic dose of abrin, (1.25 microg/kg body wt) consecutively for five days in normal mice stimulated specific humoral responses. A noticeable increase was observed in total leucocyte count, lymphocytosis, weights of spleen and thymus, circulating antibody titre, antibody forming cells, bone marrow cellularity and alpha-esterase positive bone marrow cells. The results suggest that abrin can...

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...

Macroscopic and Microscopic Evaluation of Abrus Precatorius L. (gunja), Seeds

The excessive exploitation of medicinal plants during recent years raises the issues regarding their quality, safety and efficacy. In this respect, there has been a rapid increase in the standardization of medicinal plants with therapeutic potential. In spite of the new techniques, identification and evaluation of plant drugs pharmacognostic study is more cheap and reliable. Abrus precatorius L...
