Photoluminescence of plant extract solutions has been investigated for discrimination of plant life forms (grasses, forbs, and shrubs) using principal component analysis (PCA). Clippings from each of six plant species representing three different plant life forms potentially found in the diets of free-ranging herbivores in the Chihuahuan Desert of North America were investigated for possible di...

Skin health is increasingly becoming an important aspect of primary health care among many communities particularly because of the increased challenge of HIV-AIDS, skin conditions being among the common opportunistic diseases in immuno-compromised individuals. This study investigated the use of traditional remedies in managing various skin conditions in the Central Province of Kenya. Fifty-seve...

background : mosquitoes transmit serious human diseases, causing millions of death every year. vector control is facing a threat due to the emergence of resistance to synthetic insecticides. insecticides of botanical origin may serve as suitable alternative biocontrol techniques in the future. nine different locally available medicinally important plants suspected to posse larvicidal property w...

background the production of nanoparticles using a biosystem is considered green chemistry. application of plant extracts as a biological process has been proven to be suitable for synthesis of nanoparticles. objectives this study designed in order to evaluate the production of silver nanoparticles using juglans regia leaf extract and to compare the outcome of different preparation methods of p...

objective(s):one strategy for the treatment of diabetes is inhibition of pancreatic α- amylase. plants contains different chemical constituents with potential for inhibition of α-amylase and hence maybe used as therapeutic. materials and methods: urtica dioica and juglans regia linn were tested for α-amylase inhibition. different concentrations of leaf aqueous extracts were incubated with enzym...

In this study, we present a proposal for the physical and chemical quality control of the powder of the species T. parthenium (feverfew) and its hydroalcoholic extract obtained by percolation. The sesquiterpene lactone parthenolide, the main active compound of this plant, was quantifi ed by HPLC and its content was found to be 0.49% in the powder and 1.06% in the extract. The total content of f...

Acalypha manniana (Euphorbiaceae) is a plant popularly used in Cameroon and in several parts of Africa for the treatment of various microbial diseases like diarrhea and skin infections. The present study was designed to evaluate the phytochemical composition, antimicrobial and radical-scavenging activities of A. manniana methanol leaf extract and its fractions. The methanol extract was partitio...

lycium species is a popular medicinal plant in the traditional chinese medicine and lycium ruthenicum is a native medicinal plant of iran. lycium genus has several biologically important properties too. investigation of chemical composition of ethyl acetate extract of this plant is the goal of this study. two coumarins (scopoletin and sculetin) and methyl-2-hydroxy-4-undecanoxy-trans-cinamate w...

in order to find the plant extracts with antifungal activity, 18 plant species were screened. in this study, distilled water, methanol, chloroform, aceton and ethanol were employed to obtain crude extract from plant samples. the extracts were tested against sugar beet root rot agents, rhizoctonia solani and phytophthora drechsleri. the inhibitory effect of different extracts was investigated by...

Mapungubwe Cultural Landscape (MCL) woody vegetation was characterized to establish structural and compositional attributes. Stratified random sampling based on major soil types was used and nine plant variables were measured in 137(20x30) m2 sampling plots; these being genera, species and family names; basal circumference; plant height; depth and diameter of tree canopy; number of s...
