printing and packaging industries make three phases of solid, liquid and gaseous contaminants which can cause very dangerous problems. the presence of alcohols, inks, and cleaners can result in massive range of industrial pollutants. always respiratory problems, fatigue, dizziness, weakness, abnormal behavior, memory impairment, insomnia, loss of appetite, and impaired vision and hearing and ca...

Natural products from fungi are reported for various anticancer, antioxidant and other biological activities. So in search for novel bioactives from fungi isolated and identified from infected leaves of Rhododendron sp. Thus the isolated fungus was identified as Monochaetia kansensis, was extracted with variety of solvents of increasing polarity such as chloroform, Dichloromethane and ethylacet...

The aim of the study was to analyze the constituents of the dichloromethane fraction obtained from A. moluccana and also to evaluate the anti-inflammatory and antinociceptive properties of α,β-amyrenone isolated from A. moluccana in mice. The dichloromethane fraction was evaluated by gas chromatography and submitted to purification. The mixture of α,β-amyrenone was isolated and then evaluated u...

The dermatophytes are filamentous fungi that cause cutaneous fungal infections because they use keratin as a nutrient source. For this study the antidermatophyte activity of the extracts and derivates from leaves of Piper regnellii was analyzed. From the dichloromethane extract (EBD) neolignans such as eupomatenoid-3 and eupomatenoid-5 were obtained, and it was submitted to fractionation to rem...

Ethanol extract and fractions obtained from leaves of Solanum lycocarpum were examined in order to determine their phenolic composition, antioxidant, antibacterial, anti-inflammatory, and cytotoxic potential. High performance liquid chromatography coupled with DAD analysis indicated that the flavonoids apigenin and kaempferol were the main phenolic compounds present in dichloromethane and ethyl...

Dichloromethane (methylene chloride) is a widely used chlorinated solvent. We review the available epidemiology studies (five cohort studies, 13 case-control studies, including seven of hematopoietic cancers), focusing on specific cancer sites. There was little indication of an increased risk of lung cancer in the cohort studies (standardized mortality ratios ranging from 0.46 to 1.21). These c...

leukemia is a blood disease which is caused by the inhibition of differentiation and an increased proliferation rate. nature has been known as a rich source of medically useful substances. high diversity of bioactive molecules extracted from marine invertebrates, makes them ideal candidates for cancer researches. the study has been done to investigate cytotoxic effects of dichloromethane brittl...

Anti-amoebic effects of crude root extracts of Senna didymobotrya against Entamoeba histolytica infecting caecum of mice were studied. Caecal amoebiasis was induced by injection of Entamoeba histolytica trophozoites directly into the caecum. Mice were treated orally with the root dichloromethane extracts, ethyl acetate extracts, methanol total extracts, methanol successive extracts, hexane extr...

Five xanthone derivatives and one flavanol were isolated from the dichloromethane extract of Garcinia mangostana. Dichloromethane, ethyl acetate extract and the major xanthone (α-mangostin) were evaluated in vitro against erythrocytic schizonts of Plasmodium falciparum, intracellular amastigotes of Leishmania infantum and Trypanosoma cruzi and free trypomastigotes of T. brucei. The major consti...
