we determined the concentrations of lead and cadmium in edible parts of colocasiaesculenta,amaranthusspp. and ipomoea batata cultivated on farms in industrially polluted sections of nyabugogomarsh (kigali, rwanda) and quantified metal intake by consumers of these crops. we report that metalconcentrations in crops were within eu limits. the highest metal concentrations were found in amaranthussp...

Polysaccharides from Morchella esculenta have been proven to be functional and helpful for humans. The purpose of this study was to investigate the chemical structure and anti-proliferating and antitumor activities of a Morchella esculenta polysaccharide (MEP) extracted by pulsed electric field (PEF) in submerged fermentation. The endo-polysaccharide was separated and purified by column chromat...

Ustilago esculenta grows within the flowering stem of the aquatic grass Zizania latifolia, resembling a fungal endophyte. The fungus colonizes Z. latifolia and induces swelling which results in the formation of galls near the base of the plant. Due to their unique flavor and textures these galls are considered as a delicacy in southern China. Efficient genetic manipulation is required to determ...

Bacterial adhesion to surfaces is the first step in biofilm formation, which leads development of conditions that may compromise health status patients. Surface modification has been proposed reduce bacterial biomaterials. The objective this work was assess and compare Streptococcus mutans surface biomimetically-modified stainless steel using different topographies. Stainless plates were modifi...

the study of the potntial for using leucaena leucocephala or manihot esculentafor supplementing feeding of west african dwarf goats were carried out from november 2003 to january 2004 inthe experimental farm of the universityof dschang. twenty four west african dwarf goats, were divided in three groups of eight animals, each one 12 months old with average weight of 13.1±4.4 kg, were used in thi...

From neurointermediate pituitary glands of Xenopus laevis and Rana esculenta, previously unreported peptides termed hydrins, active on water permeability of frog urinary bladder and frog skin (Brunn or "water-balance" effect), have been isolated and sequenced. These peptides seem to be derived from the pro-vasotocin-neurophysin precursor. Hydrin 1, found in Xenopus, has been identified as vasot...

The goal of this study was to determine the rat lens aldose reductase-inhibitory effects of 95% ethanol extracts from the leaves of C. esculenta and, its organic solvent soluble fractions, including the dichloromethane (CH2Cl2), ethyl acetate (EtOAc), n-butanol (BuOH) and water (H2O) layers, using dl-glyceraldehyde as a substrate. Ten compounds, namely tryptophan (1), orientin (2), isoorientin ...

Mutagenicity and antimutagenicity potentials were tested using Ames' test in crude distilled water and absolute ethanol extracts from the stems and leaves of Peperomia pellucida (Linn.) Kunth, Eichhornia crassipes Solms, Colocasia esculenta Schott and Brachiaria mutica (Forssk.) Stapf, and the stems of Musa sapientum Linn. No mutagenic effect was found in any of the 10 mg/plate crude extracts o...

Natural products are the best sources of drugs and drug leads this remains true today although fact that many pharmaceutical companies have focused on natural research for two decades. Colocasia esculenta (L) Schott (C. esculenta, Family Araceae) is an annual herbaceous plant with a long history usage in traditional medicine several countries across world grown its edible corm as staple foods t...
