Viburnum grandiflorum Wall. ex DC., is a plant of Himalaya and Hazara region of Pakistan which was screened for bioactive secondary metabolite and screen for biological activity. Preliminary phytochemical profiling indicated the presence of different classes of secondary plant metabolites such as alkaloids, terpenoids, saponins, anthraquinone. These secondary metabolites vary in types in differ...

The penguin wing oyster Pteria penguin whole body extract was obtained with different solvents. The whole body extracts were assayed for antibacterial activity using agar well diffusion technique against human pathogens. The extracts derived from acetone and chloroform exhibited broad antibacterial activity. Highest activity was exhibited against Klebsiella pneumoniae (6 mm) and Staphylococcus ...

The molluscicidal activity of leaf and rhizome extracts of Iris germanica L. (var. alba) against Biomphalaria alexandrina snails was evaluated and the rhizome extracts were found to be the most potent. Activity-guided fractionation revealed that the chloroform extract showed the highest molluscicidal activity (LC90 = 1.26 mg/l) among the tested extracts of the rhizomes. Fraction B prepared from...

Zanthoxylum rhetsa is an aromatic tree, known vernacularly as "Indian Prickly Ash". It has been predominantly used by Indian tribes for the treatment of many infirmities like diabetes, inflammation, rheumatism, toothache and diarrhea. In this study, we identified major volatile constituents present in different solvent fractions of Z. rhetsa bark using GC-MS analysis and isolated two tetrahydro...

Resin adsorption techniques using three types of resin (DAX-8, AG-MP-50, and WA-10) were employed to characterize the raw water (RW) from the major 3 million m3/day (793 million gal/day) drinking water treatment plant in Bangkok, Thailand. The dissolved organic carbon (DOC) mass distribution sequences of the six organic fractions in raw water, from high to low, were hydrophilic neutral (HPIN), ...

In the search for novel chemical scaffolds leading to potential antihypertensive agents, the methanol extract of Murraya paniculata leaves was assessed for its effects on isolated rat aorta rings. The vasorelaxing effect of the chloroform fraction of the methanol plant extract was the most potent for its vasorelaxing activity on rat aorta rings contracted by 60 mM K(+) (K60). Two coumarins were...

Tuberculosis still remains a leading cause of death in the world. Currently considerable interest in natural products and their derivatives in the area of drug research for multidrug resistant tuberculosis (MDR-TB). The present investigation focused on identification, isolation, characterization of lead constituents and to determine the antitubercular activity of their enriched fractions and is...

Phlomis bruguieri is a native plant in Iran, which deserves phytochemical study. The aim of this study was evaluation its iridoid contents along with antioxidant capacity. Aerial parts the material were extracted methanol and applied on repeated normal column chromatography using hexane: chloroform (70:30), chloroform: (90:10), (100%). fraction eluted (100%) containing polar glycosides selected...
