The antiretroviral activities of extracts of Euphorbia hirta were investigated in vitro on the MT4 human T lymphocyte cell line. The cytotoxicities of the extracts were tested by means of the MTT cell proliferation assay, and then the direct effects of the aqueous extract on HIV-1, HIV-2 and SIV(mac251) reverse transcriptase (RT) activity were determined. A dose-dependent inhibition of RT activ...

Intraspecific variation was examined among 25 mitochondrial DNAs (mtDNAs), representing between two and five lines of eight agriculturally important Brassica species. Each of the approximately 140 restriction sites surveyed was invariant within each species. Only two length polymorphisms, deletions of 700 bp and 100 bp in a Brassica nigra line, were detected. A single inversion polymorphism was...

The present investigation aims to evaluate biomimetic synthesis of silver nanoparticles using endophytic bacterium EH 419 inhabiting Euphorbia hirta L. The synthesized nanoparticles were initially confirmed with change in color from the reaction mixture to brown indicating the synthesis of nanoparticles. Further confirmation was achieved with the characteristic absorption peak at 440 nm using U...

Antimicrobial activity and cytotoxicity of fifty one extracts of different parts of 14 plants were studied. Ethanol, methanol, aqueous, butanol, and n-hexane extracts were tested against three gram negative, two gram positive bacteria, and two fungi. Cytotoxicity and phytochemical screening were determined using MTT and TLC assays, respectively. Of the fifty one extracts, twenty two showed acti...

The present communication is reports a new record of Usnea hirta (L.) Weber ex F.H.Wigg. family Parmeliaceae collected from the Western Ghats Karnataka. differs already known U. ghattensis in having norstictic acid, fatty acid murolic group and presence isidia thallus.

Euphorbia hirta is a common medicinal plant in folk and traditional medicine systems. This has shown promising effects against several human ailments infectious diseases. Therefore, it important to summarize the activities value of hirta. The main intent this literature review was phytochemical content pharmacological applications about pharmacology phytochemistry collected from different globa...

We assessed evidence of exposure to viruses and bacteria in an unmanaged and long-isolated population of Soay sheep (Ovis aries) inhabiting Hirta, in the St Kilda archipelago, 65 km west of Benbecula in the Outer Hebrides of Scotland. The sheep harbour many metazoan and protozoan parasites but their exposure to viral and bacterial pathogens is unknown. We tested for herpes viral DNA in leucocyt...
