Phytochemical screening, gas chromatography-mass spectrometry (GC-MS) analysis of phytochemical constituents and anti-bacterial activity of Aerva lanata (L.) leaves

The present study is aimed to determine the phytochemical screening and anti-bacterial activity of the extracts (acetone, ethyl acetate and ethanol) of medicinal plant, Aerva lanata leaves against bacterial strains. Acetone, ethyl acetate and ethanol extracts of A. lanata leaves were prepared using Soxhlet apparatus. These extracts of A. lanata leaves were checked for their anti-bacterial activity by well diffusion,...

Effects of volatile oils of the Microlobius foetidus on trypsin, chymotrypsin and acetylcholinesterase activities in Aedes aegypti (Diptera: Culicidae)

Volatile oils of Microlobius foetidus were used for the evaluation of mortality, trypsin, chymotrypsin and acetylcholine inhibition and Aedes aegypti morphology. Bioassays were made with different concentrations (25, 50 and 100 μg/ml) and alterations in the gut of 4th stage larvae were observed. Volatile oils affected larvae in all stages, with 100% mortality for the 100 μg/ml concentration (LD50 >33.02). The...

Evaluation of activity exerted by a steroid derivative on injury by ischaemia/reperfusion

There are reports which indicate that some steroid derivatives have activity atcardiovascular level; nevertheless, there is scarce information about the effects exerted by the progesterone derivatives on cardiac injury caused by ischemia/reperfusion. In this study, a new steroid (progesterone derivative) was synthetized with the objective of evaluating its activity on ischemia/reperfusion injury. The Langendorff...
