Hemagglutinin from the Root Tuber of Pax.

Objectives: In this study, root tuber hemagglutinin was purified and its physicochemical properties were determined. The antioxidative and anti-hemolytic activities of the hemagglutinin were also investigated.

Materials And Methods: The hemagglutinating assay was used to detect the presence of lectin in the phosphate-buffered saline extract of the root tuber.

Bioactivities of Garcinia kola enzymatic hydrolysates at different enzyme-substrate ratios.

Natural products, such as enzymatic hydrolysates and bioactive peptides from dietary sources, are safe alternatives to synthetic compounds linked to various deleterious effects. The purpose of this study is to determine the in vitro bioactivities (antioxidant and anti-inflammatory activities) of Garcinia kola seeds enzymatic hydrolysates (GKPHs) at different enzyme (pepsin)-substrate ratios.

Physicochemical properties and acute toxicity studies of a lectin from the saline extract of the fruiting bodies of the shiitake mushroom, Lentinula edodes (Berk).

A lectin (LEL) was isolated from the fresh fruiting bodies of the shiitake mushroom Lentinula edodes by a combination of gel filtration chromatography on Sephadex G-150 and affinity chromatography on an N-acetyl-Dgalactosamine-Sepharose 4B column. Its molecular mass, as determined by gel filtration, was estimated to be 71, 000 Daltons and its structure is homotetrameric with subunit molecular weight of approximately 18,000 Daltons. LEL agglutinated non-specifically red blood cells from the human ABO system as well as rabbit erythrocytes and in haemagglutination inhibition assays, exhibited sugar-binding specificity toward N-acetyl-D-galactosamine.
