A phytochemical survey for alkaloid-containing plants has been conducted in South Sumatra including traditional medicinal plants. During the 180 satisfactory herbarium sample were obtained and all of them tested alkaloids. The results showed that 33 species gave a positive test alkaloids, high alkaloid contents shown by: Alstonia scholaris, angustiloba, Ervatamia coronariaa, Voacanga foetida Bl...

Aims: The present research is focused on screening in vivo anti-ulcer activity using pylorus ligation and ethanol induced ulcer model. 
 Study Design: Fourty eight rats, randomly divided into groups, were used this study. Bark of Alstonia scholaris air-dried, ground fine powder the preparation an ethanolic extract.
 Place Duration Study: Department Pharmacology, Osmania University, Hy...

Extracts from eleven different plant species such as jute (Corchorus capsularis L.), cheerota (Swertia chiraita Ham.), chatim (Alstonia scholaris L.), mander (Erythrina variegata), bael (Aegle marmelos L.), marigold (Tagetes erecta), onion (Allium cepa), garlic (Allium sativum L.), neem (Azadiracta indica), lime (Citrus aurantifolia), and turmeric (Curcuma longa L.) were tested for antibacteria...

We present the results of an abundance analysis for a sample of stars with −4 <[Fe/H]< −2. The data were obtained with the HIRES spectrograph at Keck Observatory. The set includes 28 stars, with effective temperature ranging from 4800 to 6600 K. For 13 stars with [Fe/H]< −2.6, including nine with [Fe/H]< −3.0, and one with [Fe/H]= −4.0, these are the first reported detailed abundances. For the ...

In the present study, we report greener, simple, cost effective, non-hazardous and ecofriendly synthesis of silver (Ag) nanoparticles from Alstonia scholaris (L.) R. Br. for first time. The using leaf stock acted as a reducing well capping agent simultaneously. bio-reduced were characterized ultra violet-visible spectroscopy (UV) exhibiting blue shift absorption peak in region 440 nm. newly syn...

To determine if either herbaceous or woody plants are more competitive with longleaf pine (Pinuspalustris P. Mill.) seedlings, two vegetation management treatments-herbaceous plant control (HPC, No or Yes) and woody plant control (WPC, No or Yes) were applied in newly established longleaf pine plantings in a randomized complete block 2 x 2 factorial design in two studies (a = 0.05). Both studie...

We use a series of high-resolution simulations of a ‘Milky-Way’ halo coupled to semianalytic methods to study the formation of our own Galaxy and of its stellar halo. The physical properties of our model Milky Way, as well as the age and metallicity distribution of stars in the different components, are in relatively good agreement with observational measurements. Assuming that the stellar halo...

Mature trees of eastern white, jack, Scotch, and shortleaf pines were inoculated with 25,000-34,000 pinewood nematodes, Bursaphelenchus xylophilus, isolated from infected Scotch pines in Missouri. Equal numbers of trees of each species inoculated with distilled water served as controls. Nine of fifteen Scotch pines died within 4 months of nematode infection or during the winter and early spring...
