To see the relative tolerance of the plant species, ten different plant species i.e. Ficus rumphii, Pongamia pinnata, Alstonia scholaris, Holoptelea integrifolia, Saraca indica, Pithecolobium dulcis, Cassia simea, Bauhinia variegata, Azadirachta indica and Grewelia robusta was taken from residential (SI), industrial (SII) and commercial (SIII) area of the city as this florais very much common t...

This study was carried out to assess the radioprotective effect of Alstonia scholaris against gamma irradiation in mice. Adult Swiss albino mice were exposed to different doses of gamma radiation in the presence (experimental) or absence (control) of Alstonia scholaris extract (ASE). Dose tolerance of ASE, DRF, CFU colonies in spleen, LPx and GSH were studied. The optimum dose for radioprotecti...

Alstonia scholaris (L.) R. Br. is a plant of family Apocynaceae and has a great medicinal importance. It is widely used by tribal people to treat various diseases and ailments. The present communication deals with the organoleptic and preliminary physico-phytochemical studies of the stem bark of the plant. The organoleptic study was done according to the W.H.O. guidelines for medicinal plants. ...

Folkloric use of root-bark extract of Alstonia boonei in the treatment and management of many disease conditions may be associated with free radical scavenging as part of its mechanisms of action. We therefore evaluated the ability of different solvent fractions of the methanol extract, crude precipitate from the extract, and isolated compound from the crude precipitate for scavenging 2,2-diphe...

OBJECTIVES The present study was carried out to investigate the in vivo antimycobacterial activity of methanol extract of Alstonia scholaris and Mucuna imbricata in murine model. MATERIALS AND METHODS Female BALB/c mice were infected with the Mycobacterium tuberculosis H37Rv suspension. Extracts were administered orally for 2 weeks from 7th day postinfection at a dose of 200 mg/kg and rifampi...

One of the biological wealth that grows in Papua is Alstonia scholaris, known by Maybrat tribe as swe plant and used a traditional medicine for antidiabetic. The Swe tree contains lot white sap tastes very bitter. There also bitter taste roots, bark, leaves so it thought to contain bioactive compounds alkaloids which have potential This study aims extract determine antidiabetic activity inhibit...

In this research, the foliar uptake patterns of three toxic metals (Pb, Cd, and Cu) bound to airborne particulate matter (PM) were investigated using two evergreen tree species (Senna siamea Alstonia scholaris) at six different locations (two residential, traffic, commercial, industrial) plus one control site in a subtropical urban environment. The concentrations Pb, Cu measured from dust, leaf...

This report describes the synthesis of metallic silver nanoparticles (AgNPs) using extracts of four medicinal plants (Aegle marmelos (A. marmelos), Alstonia scholaris (A. scholaris), Andrographis paniculata (A. paniculata) and Centella asiatica (C. asiatica)). The bio-conjugates were characterized by UV–visible spectroscopy, scanning electron microscopyenergy dispersive spectroscopy (SEM-EDS), ...
