AIM To examine the efficacy of three extraction techniques: Soxhlet-extraction (SE), cold-maceration (CM) and microwave-assisted-extraction (MAE) using 80% methanol as solvent. METHODS The study was performed on each of 50 g of Vernonia amygdalina (VA) and Occimum gratissimum (OG) leaves respectively. The percentage yield, duration of extraction, volume of solvent used, qualitative and quanti...

Fresh leaves of vitex negundu were collected and macroscopic and microscopic characters were determined. Soxhlet extraction of the powdered leavers was carried out using petroleum ether (40:60) and chloroform. Idenitification of important phytoconstituents was carried out. Characterization by TLC showed the presence of vitexin. The processed leaf extract was tested for antimicrobial activity. T...

Different types of terpenoids were separated from extract of bark of Oroxylum indicum. The composition of phytoconstituents terpenoids was determined by GC and GC-Mass technique. Sixteen components were identified, out of which three components are major constituents. Identification of all the components was done by spectral studies, retention time and by comparing with standards. PHYTOCHEMISTRY

objective: the present study was conducted to detect possible chemicals (phytoconstituents), prove ethno-medicinal value of the plant, and investigate antimicrobial, anthelmintic, and total phenolic content of crude methanolic extract of the solanum violaceum plant.  materials and methods: phytochemical screening was carried out using different chemical group test methods. in anthelmintic activ...

Underutilized legumes are common crops in developing countries with superior dietary potentials that could be useful sources of protein as well some phytoconstituents. They more tolerant abiotic environmental conditions like drought than the major legumes. This makes them adapted to harsh soil and climatic conditions, which helps minimize pressure brought on by climate change. However, despite ...
