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 ...
متن کاملLeaf-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...
متن کاملStudies 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...
متن کاملInfluence of Rhizobia Inoculation on Biomass Gain and Tissue Nitrogen Content of Leucaena leucocephala Seedlings under Drought
Anticipated increases in the frequency of heat waves and drought spells may have negative effects on the ability of leguminous trees to fix nitrogen (N). In seedlings of Leucaena leucocephala inoculated with Mesorhizobium loti or Rhizobium tropici, we investigated how the developmental stage and a short drought influenced overall biomass and the accumulation of carbon and N in plant tissues. In...
متن کاملSustain-Release of Various Drugs from Leucaena Leucocephala Polysaccharide
This study examines the sustained release behavior of both water-soluble (acetaminophen, caffeine, theophylline and salicylic acid) and water-insoluble (indomethacin) drugs from Leucaena leucocephala seed Gum isolated from Leucaena leucocephala kernel powder. It further investigates the effect of incorporation of diluents like microcrystalline cellulose and lactose on release of caffeine and pa...
