From the stem bark hexanic extract of Garcinia chapelieri, chapexanthone A, B were isolated using combinations of column and thin-layer chromatographic methods. Their structures were elucidated by NMR spectroscopic methods, mainly 1D and 2D NMR.

FireStem2D, a software tool for predicting tree stem heating and injury in forest fires, is a physically-based, two-dimensional model of stem thermodynamics that results from heating at the bark surface. It builds on an earlier one-dimensional model (FireStem) and provides improved capabilities for predicting fire-induced mortality and injury before a fire occurs by resolving stem moisture loss...

A new acyclic triterpenoid, sapelenin G (1) was isolated from the stem bark of Entandrophragma cylindricum. Its structure was determined from spectroscopic data and by chemical transformation. © 2007 International Formulae Group. All rights reserved.

Seventy isolates belonging to 3 different species of gram-negative bacilli: E.coli(30), K.pneurnoniae(05), and P.aeruginosa(05), and I specie of gram-positive cocci: S.aureus(30), were used for screening of antibacterial activity of aqueous infusion, decoction and essential oil of cinnamon by standard disc diffusion method. The oil of cinnamon exhibited highest antibacterial activity against S....

The stem heartwood of Lophira alata Banks ex C. F. Gaertn. (Ochnaceae), also called “bongossi”, shows strong resistance against destructive fungi and bacteria and is extensively exploited as fi rst-grade timber. Both aqueous and alcohol extracts of either the leaves, the stem bark or the stem heartwood of this plant are extensively used as antiseptics by many tribes in the central and southern ...

BACKGROUND Gastric peptic ulcer is one of the common disorders of gastrointestinal tract, which occur due to an imbalance between the offensive and defensive factors. It is an illness that affects a considerable number of people worldwide. This study was conducted to evaluate the antiulcerogenic and antiulcer effects and recognize the basic mechanism of action of Piptadeniastrum africanum stem ...

BACKGROUND The present study was carried out to assess the phytochemical and anti-dermatophytic effect of the leaf and bark extracts of Xylosma longifolium Clos. The leaf and stem bark are used by the indigenous people of Manipur, India for treatment of skin diseases. METHODS The leaves and stem barks of Xylosma longifolium were extracted using petroleum ether, chloroform and methanol respect...

This study aimed to evaluate the phytochemical components, antioxidant capacity, and antimicrobial effects of Diospyros villosa (L.) De Winter leaves stem bark. The extracts were obtained using different media (methanol, chloroform, hexane). DPPH FRAP methods used assess activity Folin–Ciocalteu method was determine total phenolic contents crude extracts. against five pathogenic bacteria determ...

amount of information about what contemporaries felt they knew and what they did in actual practice. The first twothirds of the book covers such topics as remedies, diseases, healthy living, surgery and the knowledge, prevention and cure of the plague. And through this Part I, Wear addresses the similarities, differences, continuities and changes reflected in the ideas and practices of learned ...

Subcutaneous treatment of 50% EtOH extract of neem bark (Azadirachta indica A. juss) to male rats at the dose of 10 mg for 30 days caused arrest of spermatogenesis. The diameter of serminiferous tubule, Leydig cell nucleus and epithelial heights of epididymides were significantly reduced (p≤0.001). Sperm motility and density were significantly reduced. Reduced testicular and accessory organ pro...
