Studies on Leucaena Leucocephala Seed Gum: Rheological Properties

The apparent viscosity (pseudoplastic viscosity) of mucilage of leucaena seed gum was calculated, based on flow curves, obtamed With multiple point viscometer. Attempts were made to correlate the various rheological properties, describIng the_ overall flow behaviOur of gum, with their concentrations. The relationship between N(exponential constant) and concentration was found to be a zero order...

Leaf-closing substance in Leucaena leucocephala.

Potassium (2R,3R)-2,3,4-trihydroxy-2-methylbutanoate (1) was identified as a leaf-closing substance in the nyctinastic plant, Leucaena leucocephala. Compound 1 showed strong leaf-closing activity toward L. leucocephala and was not effective against other nyctinastic plants. The potassium ion was indispensable for the bioactivity of 1. Compound 1 gradually lost its bioactivity because of the exc...

Anthelmintic activity of Leucaena leucocephala protein extracts on Haemonchus contortus.

The objective of this study was to evaluate the effects of protein extracts obtained from the plant Leucaena leucocephala on the nematode parasite Haemonchus contortus. The seeds, shell and cotyledon of L. leucocephala were separated and their proteins extracted using a sodium phosphate buffer, and named as TE (total seed extract), SE (shell extract) and CE (cotyledon extract). Soluble protein ...

Studies on disintegrant action of Leucaena leucocephala seed gum in ibuprofen tablet and its mechanism

Leucaena (Leucaena leucocephala) seed gum (LSG) was evaluated for disintegrant action in lactose (soluble) based tablets containing ibuprofen, a relatively insoluble drug. The properties of tablets evaluated include weight uniformity, hardness, friability, disintegration time and in vitro dissolution (k, T 50 , A 30 ). LSG, at low concentration level (2% w/w), can be used as a disintegrant in t...
