Three flavonoids were isolated for the first time from the Sudanese medicinal plants Albizia zygia. Compounds 1-3 were identified by interpretation of ESI mass data, (1)H, (13)C and 2D NMR as well as by comparison with published data as 4',7-dihydroxyflavanone (1) 3',4',7-trihydroxyflavone (2), 3-O-methylfisetin (3',4',7-trihydroxy-3-methoxyflavone, 3). All flavonoids were tested against Plasmo...

The investigation was aimed to evaluate the antifungal and antifumonisin activities of budmunchiamine A and pithecolobine against Fusarium verticillioides. The budmunchiamine A was isolated from Albizia amara and pithecolobine from Albizia saman. The results demonstrated that both budmunchiamine A and pithecolobine significantly inhibited the growth and fumonisin B1 production by F. verticillio...

Background Albizia zygia is used in Ghanaian traditional medicine for the management of mental disorders. The present study tested the hypothesis that an extract of the leaves of Albizia zygia (AZE) may possess antipsychotic and antidepressant properties. Method The novelty- and apomorphine-induced locomotor and rearing behaviours of AZE in mice were explored in an open-field observational te...

Invasive species (IS) threaten biodiversity and ecosystem functioning. To achieve landscape-scale reductions in IS and the associated gains for biodiversity, IS control efforts must be expanded across private lands. Enhancing IS control across private lands requires an understanding of the factors that motivate residents to engage or prohibit residents from engaging in efforts to control IS. Dr...

Soil pH declined from 5.9 to 5.0 in 8 years beneath plantations of Eucalyptus saligna (Sm.) in Hawaii. In stands of Albizia falcataria, (L.) Fosberg, the soil pH change was more dramatic, declining from 5.9 to 4.6. We measured several components of soil acidity beneath four mixtures of the two tree species to gain insight on the processes responsible for the decline in soil pH. These components...

the inhibitory activities of aqueous and solvent extracts of twelve selected medicinal plants were evaluated against biosynthesis of aflatoxin b1 (afb1) by aspergillus flavus. the a. flavus was isolated from maize, and aflatoxin b1 biosynthesis was confirmed by comparison with standard afb1 using tlc method. in vivo antiaflatoxigenic efficacies of activity guided solvent extracts were determine...

The antioxidative activities of the ethanol and aqueous extracts of the leaf and root samples of Albizia antunesiana were determined across a series of four in vitro models. The results showed that all the extracts had reducing power (Fe(3+)- Fe2+), DPPH, hydroxyl and nitric oxide radical scavenging abilities. The ethanol root extract had more potent antioxidant power in all the experimental mo...

Rheological properties of waxy barley flour (WBF) dispersions mixed with various gums (carboxyl methyl celluleose, guar gum, gum arabic, konjac gum, locust bean gum, tara gum, and xanthan gum) at different gum concentrations were examined in steady and dynamic shear. WBF-gum mixture samples showed a clear trend of shear-thinning behavior and had a non-Newtonian nature with yield stress. Rheolog...

Falcataria moluccana (albizia) is an exotic nitrogen (N)-fixing tree currently invading riparian forests in Hawai‘i, U.S.A. This study examined how this invasion is impacting stream ecosystems by using naturally occurring stable isotopes of carbon (C) and N to compare food web structure between a noninvaded and an albizia-invaded stream reach on the island of Hawai‘i. Isotopic signatures of par...

This paper deals with intended to determine the decay resistance of mango (Mangifera indica) and raintree (Albizia saman) wood in fungal field test. In test, a white rot fungus (Schizophyllum commune) was used laboratory. The average weight loss Mangifera indica Albizia saman blocks inoculated for 16 weeks were 35.28% 23.80% respectively. test 42.36% 28.54% respectively M. A. wood. both degrada...
