potential tree species for use in the restoration of unsanitary landfills.given that they represent the most economical option for disposing of refuse, waste landfills are widespread in urban areas. however, landfills generate air and water pollution and require restoration for landscape development. a number of unsanitary waste landfills have caused severe environmental problems in developing countries. this study aimed to investigate the colonization status of different tree species on waste landfills to assess their potential for restoring unsanitary landfills in s ...200516132448
novel hosts of the eucalyptus canker pathogen chrysoporthe cubensis and a new chrysoporthe species from colombia.the pathogen chrysoporthe cubensis (formerly cryphonectria cubensis) is best known for the important canker disease that it causes on eucalyptus species. this fungus is also a pathogen of syzygium aromaticum (clove), which is native to indonesia, and like eucalyptus, is a member of myrtaceae. furthermore, c. cubensis has been found on miconia spp. native to south america and residing in melastomataceae. recent surveys have yielded c. cubensis isolates from new hosts, characterized in this study ...200616876702
evaluation of toxicity of plant extracts against vector of lymphatic filariasis, culex quinquefasciatus.conventional insecticides are generally used as larvicides to control culex quinquefasciatus, vector of lymphatic filariasis. this study was undertaken to evaluate the larvicidal activity of some potential larvicidal plants leaf extracts against cx. quinquefasciatus larvae.022561628
phytochemical screening and antimicrobial activities of the constituents isolated from koelreuteria paniculata leaves.methanolic extract of golden rain leaves was fractionated by column chromatography on silica gel and 18 fractions were obtained. antimicrobial activities of fractions were investigated against bacillus subtilis, staphylococcus aureus, escherichia coli and pseudomonas aeruginosa as quality control bacteria and fungus pyricularia grisea which causes blast disease in rice. fractions showed more antibacterial activity at 0.04 g/ml concentration only on b. subtilis and s. aureus as gram positive bact ...201525813082
new triterpenoidal saponins from koelreuteria paniculata.bioassay guided fractionation and chemical investigation of the ethanolic extract of the aerial parts of koelreuteria paniculata laxm. (sapindaceae), resulted in the isolation and identification of three new triterpenoid saponins 1-3 named paniculatosoid a-c, along with eleven known compounds. the structures of the isolated compounds were elucidated using 1d and 2d nmr experiments, hresims, and comparison with literature data. the occurrence of tridesmosidic saponin is reported for the first tim ...201628250867
purification and characterization of an n-acetylglucosamine-binding lectin from koelreuteria paniculata seeds and its effect on the larval development of callosobruchus maculatus (coleoptera: bruchidae) and anagasta kuehniella (lepidoptera: pyralidae).this study describes the purification of an n-acetylglucosamine-binding lectin from koelreuteria paniculata seeds and its effects on the larval development of callobruchus maculatus and anagasta kuehniella. the lectin (kplec) was characterized and isolated by gel filtration, affinity column, and reverse phase chromatography. sds-page indicated that this lectin is a dimer composed of subunits of 22 and 44 kda. the n terminus exhibited 40% similarity with urtiga dioica agglutinin. kplec was tested ...200312720380
assessing the capacity of plant species to accumulate particulate matter in beijing, china.air pollution causes serious problems in spring in northern china; therefore, studying the ability of different plants to accumulate particulate matter (pm) at the beginning of the growing season may benefit urban planners in their attempts to control air pollution. this study evaluated deposits of pm on the leaves and in the wax layer of 35 species (11 shrubs, 24 trees) in beijing, china. differences in the accumulation of pm were observed between species. cephalotaxus sinensis, euonymus japoni ...201526506104
[atmospheric particle retaining function of common deciduous tree species leaves in beijing].in order to explore the atmospheric particle-retaining function of common deciduous tree species leaves in beijing, six typical tree species (populus, robinia pseudoacacia, koelreuteria paniculata, salix babylonica, acer truncatum, ginkgo biloba) were chosen to measure retaining amount of unit leaf area of air total suspended particles (tsp), coarse particles and fine particulate with aerosol generator (qrjzfsq-i). the results showed that (1) all six tree species leaves had a certain level of re ...201526387301
