An experimental arrangement is described which enables high quality 31P NMR spectra of compressed spinach leaf pieces to be continuously recorded in which all the resonances observed (cytoplasmic and vacuolar Pi, glycerate-3-P, nucleotides) were sharp and well resolved. 31P NMR spectra obtained from intact chloroplasts showed a distinct peak of stromal Pi. An upfield shift of the stromal Pi res...

The purpose of this study was to evaluate the effects of extracts of Coptidis rhizoma, Phellodendri cortex and Gardeniae fructus, which are medicinal herbs in Orengedoku-to (Huanglin-Jie-Du-Tang in Chinese), and crocetin (a major component of Gardeniae fructus) on experimental elevation of aqueous flare in pigmented rabbits. To produce aqueous flare elevation, 0.5 microg/kg lipopolysaccharide (...

Clerodendrum umbellatum Poir (Verbenaceae) is traditionally used in Cameroon for the treatment of many diseases including intestinal helminthiasis. This study was undertaken to assess the in vivo antischistosomal activity of its leaves aqueous extract on a Schistosoma mansoni mice model and to determine the most effective dose of this extract. Mice showing a patent infection of S. mansoni were ...

to determine the neuropharmacological activity of the leaf extract of croton zambesicus in mice and chicks. the effect of aqueous leaf extract of croton zambesicus on thiopental sodium – induced sleeping time in mice, on gross locomotor activity (gla) in 2-day old chicks and effect of extract on apomorphine - induced stereotyped behavior in chicks were evaluated. the aqueous extract (1000 and 1...

The marine sponge Spongosorites halichondriodes, collected from Mumbai coastal area, was studied for presence of bioactive proteins. Sponge species was identified based on Spicules morphology. Crude protein from the sponge was extracted at the concentration of 5.3 mg/mL in methanol and 3.4 mg/mL in aqueous extract. Six bacterial species (Klebsiella pneumonia, Salmonella typhi, Staphylococcus au...

The antibacterial activity of the aqueous, ethanol, methanol and petroleum ether Soxhlet extracts of sundried stem bark of Spathodea campanulata P. Beauv. (Bignoniaceae) was investigated by testing the extracts against B. subtilis, E. coli, P. aeruginosa and S. aureus. The minimum inhibitory concentration (MIC) of the methanol extract was determined against the four bacteria strains and C. albi...

Abtract: The ethanolic and aqueous extracts of the fruits of Tetrapleura tetraptera (Fabiaceae) and seeds of Delonix regia (Bojer ex Hook.) Raf (Fabiaceae) and Raphia vinifera L. (Arecaceae) were tested on the second instar larvae of Anopheles gambiae (L) at varying concentrations. With percentage mortality, T. tetraptera (59.17%) in ethanol was the most effective followed by D. regia (42.78%) ...

In this work we investigated the impact of food disinfection on the beneficial biothiol contents in a suite of vegetables consumed daily, including spinach, green bean, asparagus, cucumber, and red pepper. Four disinfection technologies commonly studied and/or used in food processing and preservation, including hydrogen peroxide, free chlorine, and gaseous- and aqueous-phase ozone, were examine...

Effects of an aqueous extract of orthosiphon thymiflorus on acetyl choline induces contraction on isolated frog rectus abdominis muscle were studies. The aqueous extract of orthosiphon thymiflorus produced significant inhibitory effect on the dose response curve of acetyl choline. It is concluded that the aqueous extract of orthosiphon thymiflorus  may exert an inhibitory effect on the skeletal...
