Background: Malaria is a worldwide threat, which affects millions of people. Although several antimalarial has been reported, they are either not effective or toxic. This study evaluated the antimalarial efficacy and safety of stem bark aqueous extracts of Khaya grandifoliola (KG) and Enantia chlorantha (EC) in Plasmodium berghie (NK65S) infected Swiss mice. Methods: Forty-two animals were gro...

With the development of national-scale forest biomass monitoring work, accurate estimation of forest biomass on a large scale is becoming an important research topic in forestry. In this study, the stem wood, branches, stem bark, needles, roots and total biomass models for larch were developed at the regional level, using a general allometric equation, a dummy variable model, a mixed effects mo...

BACKGROUND Records have shown that Combretum adenogonium Steud. Ex A. Rich (Combretaceae) is used in traditional medicine systems of several tribes in Tanzania. This study focused on the investigation of antibacterial activity, anti-HIV-1 protease activity, toxicity properties and classes of phytochemicals in extracts from C. adenogonium Steud. Ex A. Rich (Combretaceae) to evaluate potential of...

Objective: To evaluate the hepatoprotective activity of crude aqueous and ethanol stem bark extracts of Pterocarpus santalinus (Fabaceae) using CCl 4 induced hepatic damage in male Wistar albino rats. Department of Botany, Materials and Methods: The aqueous (45 mg/ml) and ethanol (30 mg/ml) extracts of S.R.N.M.N. College of Applied stem bark in 1% gum tragacanth was administered orally for 14 d...

F IRE HAS COME to be widely llsed as a tool in wildland management, particularly in the South. Its usefulness in fire hazard reduction, removal of undesirable trees, and changing of cover types has been demonstrated. We are continually trying to improve fire lISC, however, by learning more of the specific effects of fire on different species of plants. lvlosr fire effects studies are conducted ...

This study was designed to evaluate the neuroprotective activity of ethanol extract of Pongamia pinnata stem bark in monosodium glutamate-induced neurotoxicity in rats. Neurotoxicity was induced by intraperitoneal injection of monosodium glutamate 2 g per kg body weight daily for 7 days. Ethanol extract of Pongamia pinnata stem bark (200 and 400 mg/kg) was administered orally after 1 h of monos...

Introduction: Multidrug resistance remains a major obstacle hindering successful antimalarial chemotherapy. In the current study, 50% methanol in dichloromethane extract and six compounds from the stem bark of Zanthoxylum gilletii were explored for their antiplasmodial potential against three strains of Plasmodium falciparum. Materials and Methods: The extract was obtained by cold percolation u...

Piliostigma reticulatum (Caesalpiniaceae) is used in Africa as a traditional medicine for the treatment of many diseases, such as malaria, tuberculosis and diarrhoea. We investigated the antidiarrhoeal properties of a crude ethanol extract from the stem bark of Piliostigma reticulatum (EEPR) in Wistar albino rats to substantiate its traditional use and to determine its phytochemical constituent...

1. Fire is important in the dynamics of savanna–forest boundaries, often maintaining a balance between forest advance and retreat. 2. We performed a comparative ecological study to understand how savanna and forest species differ in traits related to fire tolerance. We compared bark thickness, root and stem carbohydrates, and height of reproductive individuals within 10 congeneric pairs, each c...

Medicinal herbs are moving from fringe to mainstream use with a greater number of people seeking for remedies and health approaches from side effects caused by synthetic chemicals. This has aggravated the search for antimicrobials from plants sources. In this study, aqueous extracts of Moringa oleifera samples from different areas of India were screened for antimicrobial activity against two ye...
