INTRODUCTION The larvicidal activity of Solanum lycocarpum against Culex quinquefasciatus is unknown. METHODS We evaluated the larvicidal activity of extracts of the green fruits of Solanum lycocarpum against third and fourth instar larvae of C. quinquefasciatus. RESULTS Dichloromethane and ethyl acetate fractions showed the greatest larvicidal effect at 200mg/L (83.3% and 86.7%, respective...

The clastogenic effect of total dichloromethane, methanol and water extracts, four bioactive fractions and three individual constituents from Carthamus lanatus aerial parts were evaluated in mice by bone marrow chromosome aberration assay with mitomycin C as positive control. Significant differences in the percentage of aberrant mitosis of the extracts were observed. The dichloromethane extract...

Ethanol and dichloromethane extracts of a Brazilian green propolis from Baccharis dracunculifolia were analyzed by HPLC-APCI-MS and GC-MS, respectively. The HPLCAPCI-MS technique, at the positive mode, furnished a complete and unequivocal chemical composition of the green propolis sample. It serves as fi ngerprint for different propolis samples. The composition of the ethanol extract consisted ...

In ancient to modern system of medicine Curculigo species has been recommended for relief of different central nervous system disorders. Under this reserach study the hexane, dichloromethane, ethyl acetate, methanolic and water extracts of Curculigo orchioides root were evaluated for anxiolytic activity using Elevated Plus Maze model (EPM) and Light Dark model (LDM) in mice. The methanolic and ...

The distribution constants of amitraz and its three main metabolites (DMFF, DMF, DMA) for water–organic solvent (n-hexane, toluene, dichloromethane, chloroform) extraction systems were estimated. Based on the analysis substances in studied systems, it was established that dichloromethane is optimal choice liquid-liquid method development their simultaneous determination honey. Amitraz stability...

Radiation chemistry was used as an alternative methodology for synthesizing conducting copolymers in water and dichloromethane.

For the purpose of the development of a skin-whitening agent, Sophora flavescens was evaluated for tyrosinase inhibitory activity and its active principles were identified following activity-guided isolation. The ethanol extract and dichloromethane fraction from S. flavescens showed significant inhibition of mushroom tyrosinase. From the dichloromethane fraction, three known prenylated flavonoi...
