Many plants have been known to synthesize active secondary metabolites to protect themselves from microbial attack which have potential therapeutic applications. The soxhlet extracts of leaf and stem of Iresine herbstii using ethanol, acetone, dichloromethane and petroleum ether were investigated for their phytochemical and antibacterial activity against pathogenic bacteria and compared with th...

greenhouse and laboratory studies were conducted to examine the allelopathic effects of water extracts of pigweed (amaranthus retroflexu l.) leaf, stem, root and flower at different growth stages on canola seed germination and seedling growth. water extracts of leaf, stem, root and flower as individually, binary, ternary and quadri mixtures at 0, 50 and 100% concentrations were made and their e...

Due to the emergence and spread of malaria parasite with resistance to antimalarial drugs, discovery and development of new, safe, and affordable antimalarial are urgently needed. In this respect, medicinal plant extracts are targets to optimize antimalarial actions and restore efficacy of standard antimalarial drugs. The present study was aimed at determining the antimalarial activities of Gyn...

Medicinal plants are an important source of substances which are claimed to induce anti-inflammatory and antioxidant effects. The leaves of the olive tree (Oleaeur opaea) have been used for medicinal purposes since ancient times and research has suggested that olive leaf extracts have antimicrobial and antimutagenic properties. In this study, Olive leaf aqueous extracts were screened for their ...

The extracts of the leaves and stem bark of anacardium occidentale were screened for phytochemically for the presence of secondary metabolites and for in vitro antibacterial activity. The phytochemical screening revealed the presence of alkaloids and tannins. The methanol and aqueous leaf extracts and the methanol extract of the stem bark were tested against Klebsiella pneumoniae, Staphylococcu...

BACKGROUND Pluchea indica (L.) Less. (Asteraceae) is a perennial shrub plant with anti-inflammatory and antioxidant medicinal properties. However, the anti-cancer properties of its aqueous extracts have not been studied. The aim of this study was to investigate the anti-proliferation, anti-migration, and pro-apoptotic properties of crude aqueous extracts of P. indica leaf and root on human mali...

A laboratory experiment was conducted to investigate the efficacy of different plant derivatives against the development of the cowpea weevil, Callosobruchus maculatus (F) (Coleoptera: Bruchidae) fed on cowpea, Vigna unguiculata (W) seeds. The leaf extracts of romatic plants, Murraya koenigii and Azadirachta indica (A.Juss) were evaluated for their growth, adult mortality and oviposition inhibi...

Efforts have been made to assess some plant extracts namely, Lycopersicon esculentum, Tagetus patula, Achras sapota, Azadirachta indica, Datura metel, Cymbopogon citrates, Polyalthia longifolia, Allium sativum and Allium cepa in vitro for the management of leaf spot (tikka) disease of groundnut cultivar Dhaka-1 caused by Cercospora arachidicola and Cercosporidium personatum. Results indicated t...

The objective of this study was to evaluate total phenolic content and antioxidant activity of leaf and different parts of fruit (hull, shell, and kernel) of Bene in Ilam province. Total phenolic content was determined with the Folin- Ciocalteu Reagent (FCR); antioxidant activity of methanolic extracts were examined by DPPH (2,2diphenyl- 1- picrylhydrazyl), FRAP (ferric reducing antioxidant pow...

BACKGROUND Duabanga grandiflora or known in Malaysia as Berembang Bukit, Megawasih, or Pedada Bukit, is a native plant of the Southeast Asian countries. In this study, the anti-viral properties of D. grandiflora were investigated. METHODS The D. grandiflora leaf extracts were obtained with ethyl acetate, hexane, and ethanol as solvents and labelled 37 leaf ethyl acetate (37 L EA), 37 leaf hex...
