Crude leaf extracts

The bioreduction of Zinc nitrate hexahydrate using crude leaf extract of Gulmohar, by a combustion method at 400 oC was carried out to form the ZnO nanostructures. The structural, morphological and optic properties of the nanostructures were characterized by UV- Visible spectroscopy, XRD analysis, FTIR spectroscopy, SEM, and TEM.

This study was conducted to evaluate the effect of crude and different solvent extract of Leaf of Lantana camara, an aggressive invasive weed against plant pathogenic fungi Colletorichum falcatum causing Red rot of sugarcane disease under in vitro conditions. Aqueous crude extract and solvent extracts such as extracts Methanol, Ethyl acetate, Chloroform were tested at 2mg/mL, 4mg/mL and 8mg/mL concentrations. Results revealed that all the 3 solvent extracts showed significant inhibition at higher concentrations when compared to the Standard Fluconazole (15μg/ml).

The present study was intended to delineate the Anti Helminthis activity of Ankolam leaf extract. The crude extract was obtained by the employment of Soxhlet extraction method. The extract was used to screen the antagonistic activity in vitro by taking Pheretima posthumous as the study subject. B y the employment of molecular sequencing the identity of plant was confirmed as Alangium salviifolium. The results obtained proved the capability of extract to down regulate the biological activities of subject. Mortality was induced by varying concentrations (100-1000 ppm/ml).

The nutrient, minerals and vitamin analysis of Moringa oleifera leaf meal (MOLM) was analyzed in this study. Moringa leaves were harvested from different parts of Namakkal district of Tamilnadu. Stem and branches were cut from Moringa trees and spread out under the shade to dry at 35oC for seven days. The leaves were then removed manually, grounded into powder and preserved for use. The proximate analysis of sample for moisture, crude protein, crude fibre, ether extract, total ash was done as per the AOAC (1995). The nutrient composition of leaves recorded as...

Bridelia micrantha commonly known as coastal golden leaf is a member of the family Phyllanthaceae. In preliminary studies, nine fractions, named F1- F9, were obtained by fractionating the crude methanol extract of the stem bark of Bridelia micrantha using column chromatographic techniques. The F6 fraction was found to be the most active when tested for the antibacterial activity. This study is thus aimed at investigating the effect of fractionation on antibacterial activity of F6 fraction.

Sacred basil (Ocimum sanctum) is contains active ingredients such as alkaloids, enzymes and other inorganic elements. With a view to assess the fungitoxicity of Ocimum sanctum against the fungal pathogens, studies were conducted on the fungitoxicity of Ocimum sanctum against fungal pathogens. It is concluded that all the four forms i.e., crude (10%), powdered (10%), boiled (10%) and ethanol (1%) extract of Ocimum sanctum leaf significantly inhibited the growth of the test fungus viz., Rhizoctonia solani, R. bataticola, Phoma sorghina, Colletotrichum gloeosporioides, Fusarium oxysporum f.sp.

Microbes are the sources of many food poisoning cases, usually due to improperly processed food and fruit juice separation by hand or juice mill. It is now commonly accepted that fruit juice consumption is a risk factor for infection with enteric pathogens. The trouble begins when certain bacteria and other harmful pathogens spores of multiply and spread in ubiquitous and environments. However, fruit juice Sample was collected from the various places of Kanpur, India and observed the highest microbial load in nutrient agar (4.3X107 ) viz., Shivrajpur, rose bengal chloramphenicol agar (2.
