Vascular architecture of the monocot Cyperus involucratus Rottb. (Cyperaceae)
The arrangement of vascular bundles in the stems of monocots has been described repeatedly as "scattered." But to the trained eye it is clearly ordered as verified by the use of the R index of Clark and Evans. The arrangement of bundles in leaves and sclerenchyma bundles in stems are also ordered. An equation was developed for the probability distribution frequencies (pdf) for leaf intervein di...
متن کاملMorphine withdrawal attenuating effect, toxicity and alkaloid composition of Sophora alopecuroides L. var. alopecuroides
Background and objectives: The seedsof Sophora alopecuroides L. var. alopecuroides may benefit treatment of opioid dependence. Therefore, the plant alkaloid composition, toxicity and effects on morphine withdrawal were studied. Methods: The alkaloid composition was determined by GC and GC/MS analysis. Mice were made dependent by morphine injec...
متن کاملRelease of metal impurities from carbon nanomaterials influences aquatic toxicity.
Few studies have considered the environmental impacts of impurities and byproducts associated with low-efficiency nanomanufacturing processes. Here, we study the composition and aquatic toxicity of low-purity, as-produced fullerenes (C60) and metallofullerene waste solids, both of which were generated via arc-discharge synthesis. Scanning electron microscopy with energy dispersive X-ray spectro...

متن کاملEvaluation of Anti-diabetic Potential of Cyperus Pangorei Rottb. Ethylacetate Subfractions
A study was undertaken to fractionate and characterize the antidiabetic potential of Cyperus pangorei rhizomes. The column chromatography and HPTLC study was performed on ethyl acetate fraction and five sub-fractions were separated and subjected for the evaluation of antidiabetic potential in streptozotocin induced diabetic rats. The experimental data indicated that the ethyl acetate sub-fracti...
