Grewia optiva, a plant of northern area of Pakistan was screened for the natural products, antimicrobial and insecticidal activities. Phytochemical screening, using conventional natural products identification tests indicated the presence of different phytoconstituents. The ethyl acetate and methanolic extracts of the aerial parts of the tile plant revealed the presence of tannins, while terpen...

Alkylresorcinols (5-alkyl-1,3-dihydroxybenzenes) are amphiphilic phenolic lipid compounds that abundant in cereals with highest contents rye. suspected to show a wide range of favourable biological activities. For such and further testing, highly pure alkylresorcinol standards required. Especially, purities >> 98% were partly difficult obtain the past. Here, we aimed isolate most (saturated) al...

Methyl alcohol was administered in drinking water supplied ad libitum at doses of 20,000, 5,000, 500, or 0 ppm to groups of male and female Sprague-Dawley rats 8 weeks old at the start of the experiment. Animals were kept under observation until spontaneous death. Ethyl alcohol was administered by ingestion in drinking water at a concentration of 10% or 0% supplied ad libitum to groups of male ...

Tissues fixed in osmium tetroxide or in combined osmium and glutaraldehyde (Hinde), embedded in Spurr's medium, cut at 0-5-I mum and mounted in Farrants' gum medium containing ethyl gallate, show good staining of lipid-contaning structures (droplets of triglyceride, membranes, mitochondria, etc.) in the light microscope. Such preparations show moderate contrast in the electron microscope withou...

The classes and concentrations of volatile organic compounds (VOC) released from fresh and decaying strawberries were investigated and compared. In this study, a total of 147 strawberry volatiles were quantified before and after nine days of storage to explore differences in the aroma profile between fresh strawberries (storage days (SRD) of 0, 1, and 3) and those that had started to decay (SRD...

The title compound, C4H8O4Te, crystallized from a solution of Te(4+) in ethyl-ene glycol. The Te(IV) atom is in a distorted seesaw coordination defined by four O atoms from two different ethyl-eneglycate ligands. The C atoms of the ethyl-eneglycate ligands are disorderd over two positions, with population parameters of 50.3 (6) and 49.7 (6)% indicating a statistical distribution. Due to the pos...

abstract little information is available concerning morphological responses of lolium perenne cultivars (numan and speedy green) to salinity and trinexapac-ethyl treatment in initial growth. in order to evaluate the effect of salinity treatment (0, 2000, 4000 and 6000 mg/lit) and trinexapac-ethyl levels (0, 50, 100 gr/ha) on morphological responses of 'numan' and 'speedy green' in initial growt...

Helicobacter pylori is a major risk factor for gastritis, ulcers and gastric cancer. This study was aimed to determine the antimicrobial activity of the stem bark of Bridelia. micrantha on H. pylori isolated in South Africa. Extracts and clarithromycin were tested against 31 clinical strains, including a standard strain (NCTC 11638) of H. pylori, by measuring the diameters of the corresponding ...
