Antinociceptive activity of Ricinus communis L. leaves.
OBJECTIVE To evaluate the antinociceptive activity of the methanol extract of Ricinus communis leaves (MRCL). METHODS Antinociceptive activity was evaluated using acetic acid induced writhing test, formalin induced paw licking and tail immersion method in mice at doses of 100, 125 and 150 mg/kg bw. RESULTS The results indicated that MRCL exhibited considerable antinociceptive activity again...
متن کاملSynthase Gene from Ricinus communis L
1 L-myo-Inositol-1-phosphate synthase (EC 5.5.1.4, MIPS), an evolutionarily conserved enzyme protein, catalyzes the conversion of D-glucose-6-phosphate into 1 L-myo-inositol-1-phosphate (MIP), which is the fi rst and rate-limiting step in the biosynthesis of all inositol-containing compounds (Ray Chaudhuri et al., 1997; Abid et al., 2009). MIPS is found in diverse organisms, both eukaryotic and...
متن کاملLead uptake, bioaccumulation and tolerance in summer savory (Satureja hortensis L.)
The objective of this study was to determine the effects of lead (Pb) exposure on bioaccumulation, growth, and tolerance mechanisms in summer savory (Satureja hortensis L.). Plants were subjected to different levels of Pb concentrations including 0 (control), 5, 10, 25, 50 and 100 mg L-1 in growing medium. Pb treatment led to significant increase in root and shoot Pb content. Calculation of BF,...
متن کاملNitrate reductases from leaves of Ricinus (Ricinus communis L.) and spinach (Spinacia oleracea L.) have different regulatory properties.
The activity of nitrate reductase (+Mg(2+), NR(act)) in illuminated leaves from spinach, barley and pea was 50-80% of the maximum activity (+EDTA, NR(max)). However, NR from leaves of Ricinus communis L. had a 10-fold lower NR(act), while NR(max) was similar to that in spinach leaves. The low NR(act) of Ricinus was independent of day-time and nitrate nutrition, and varied only slightly with lea...
متن کاملPotential of Ricinus Communis L. and Brassica Juncea (L.) Czern. under natural and induced Pb Phytoextraction
Put “metal into the petal” of plants which literally means bioavailability and translocation of the heavy metal to the plants is an important factor in phytoextraction. A green house experiments was conducted to study potential of Ricinus communis and Brassica juncea in metal accumulation at different concentration of Pb and also the effect of the application of two different chelators i.e., ED...
