Nanoscience and nanotechnology have been rapidly developing due to the increased use of nanoparticles in several fields including health (antibacterial agents), medicine, chemistry, food, textiles, agricultural sectors, nanofluids. The study aimed biologically synthesize AgNPs using leaf stem extracts Tabernaemontana ventricosa. were successfully synthesized verified UV-visible spectroscopy; ho...

Conopharyngine, the major alkaloid present in the leaves of Tabernaemontana (Conopharyngia) pachysiphon var. cumminsi (Stapf) H. Huber was isolated and identified by Thomas & Starmer (1963). The same alkaloid has also been found in the stem bark of a Nigerian variety of the same species by Patel & Poisson (1966) and in the stem bark of Conopharyngia durissima by Renner, Prins & Stoll (1959). Co...

Extracts from leaves and stem bark of Peschiera van heurkii (Muell. Arg.) L. Allorge (syn. Tabernaemontana van heurkii Muell. Arg., Apocynaceae) have been assayed for antileishmanial and antibacterial activities. The activities were concentrated in the alkaloid fractions which yielded 20 indole and bisindole alkaloids. The strongest leishmanicidal and antibacterial activities were observed with...

The aim of the present study was to assess the effects of chronic and acute treatment of the essential oil (EO) of Kelussia odoratissima Mozaff. on the development of morphine tolerance and dependence in mice. Mice were rendered tolerant to and dependent on morphine by subcutaneous injection of morphine over a period of 5 days. Tolerance was assessed using the tail-pinch test and withdrawal sig...

During an investigation of the fungal diversity of Korean soils, four Penicillium strains could not be assigned to any described species. The strains formed monoverticillate conidiophores with occasionally a divaricate branch. The conidia were smooth or finely rough-walled, globose to broadly ellipsoidal and 2.5-3.5 × 2.0-3.0 μm in size. Their taxonomic novelty was determined using partial β-tu...

We measured anti-nociceptive activity of prim-o-glucosylcimifugin (POG), a molecule from Saposhnikovia divaricate (Turcz) Schischk. Anti-nociceptive or anti-inflammatory effects of POG on a formalin-induced tonic nociceptive response and a complete Freund's adjuvant (CFA) inoculation-induced rat arthritis pain model were studied. Single subcutaneous injections of POG produced potent anti-nocice...

Apresentamos um levantamento com informações taxonômicas e de distribuição, além uma chave identificação Apocynaceae para a Estrada Parque do Pantanal Mato Grosso Sul, Brasil. A se configura como recorte da biodiversidade pois abrange quatro suas 11 sub-regiões desse domí­nio fitogeográfico (Abobral, Nabileque, Nhecolândia Paraguai) defronta-se o Maciço Urucum. Foram localizadas 15 espécies dis...
