One hundred and ninety seven maize samples representing different cultivars, collected from different agroclimatic regions of Karnataka (India) were analysed for moisture content, mould incidence, ergosterol and extent of mycotoxin contamination. Moisture content determination by the hot-air oven method revealed significantly high levels of moisture content(More)
The present study is an effort to identify a potent chemopreventive agent against various diseases (including cancer) in which oxidative stress plays an important causative role. Here, we investigated the effect of a hydroalcoholic (80% ethanol: 20% distilled water) extract of aerial roots of Tinospora cordifolia (50 and 100mg/kg body wt./day for 2 weeks)(More)
The synthesis of a new class of 1,3-thiazolidine nucleoside analogues in which furanose oxygen atom was replaced with nitrogen atom and 2'-carbon atom with sulfur atom is described. N-tert-butoxycarbonyl-2-acyloxy-4-trityloxymethyl-1,3-thiazolidine was coupled with the pyrimidine bases like uracil, thymine, etc. in the presence of lewis acids stannic(More)
A new series of 5,6-dihydro-4H-1,2-oxazines were synthesized via hetero Diels-Alder reaction of alpha-nitrosoolefins with alkenes. alpha-Nitrosoolefins were generated from ketoximes by the action of chloramine-T. The newly synthesized compounds were characterized with IR, NMR, elemental analysis and screened for their antimicrobial activity; they exhibited(More)
Zinc oxide nanoparticles (ZnO-NPs) were synthesized for the first time from any of the species of Ceropegia. Presently, ZnO-NPs were synthesized from the leaf extract of Ceropegia candelabrum with zinc nitrate using a simple hydrothermal process. The synthesized ZnO-NPs showed an absorption peak at 320nm which is one of the characteristic features of(More)
The antioxidant properties of aqueous and solvent extract of seeds of Psoralea corylifolia L. were evaluated in vitro employing different standard assays. All the extracts tested were effective in quenching superoxide anion. Maximum superoxide scavenging activity was observed in the alcohol and water (1:1) extract (AWEP) at 200µg/ml. Lipid peroxidation was(More)
Precursors of podophyllotoxin were synthesized and screened for their antibacterial activity. The results proved that ethyl-2-(3'-methyl-4'-methoxybenzoyl)-3-(4″ methoxyphenol)-cyclopropane-1-carboxylic acid and Ethyl-2-(3'-methyl-4'-methoxybenzyol-3-1 3″, 4″-dimethoxyphenyl)-cyclopropane-carboxylic acid have significant antibacterial activity against(More)
