several attempts have so far been made in the search of new anticancer agents of plant origin. some studies have reported that different species of pine genus possess cytotoxic activities against various cancer cell lines. in the present study, we evaluated the cytotoxic effects of pinus eldarica bark and leaf extracts or leaf essential oil on hela and mcf-7 tumor cell lines. hydroalcoholic and...

The petroleum ether (60-80o), chloroform methanol extracts of leaves and root bark of ficus glomerata (Moraceae) were prepared by successive solvent extraction followed by vacuum evaporation and the marc left after successive solvent extraction was extracts with boiling water to get aqueous extracts, all the extracts were subjected to qualitative chemical tests to find out phytoconstituents pre...

OBJECTIVE To evaluate in vitro antibacterial effectiveness of five medicinal plants used by an Indian aborigine, against 8 multidrug-resistant (MDR) enteropathogenic bacteria isolated from clinical samples of under-5 hospitalized children. METHODS Antibiotic sensitivity patterns of eight clinically isolated strains of enteropathogenic bacteria, Enterobacter aerogenes, Escherichia coli, Klebsi...

BACKGROUND The emergence of drug resistant malaria is threatening our ability to treat and control malaria in the Southeast Asian region. There is an urgent need to develop novel and chemically diverse antimalarial drugs. This study aimed at evaluating the antimalarial and antioxidant potentials of Acacia nilotica plant extracts. METHODS The antioxidant activities of leaves, pods and bark ext...

In most cases the pharmacological activity of plant extracts is not assigned to single components and often not all active ingredients are known. Approaches other than those considering single compounds only to analyze plant material have proven helpful for a better characterization of extracts in their entirety. In this study extracts of willow bark are analyzed by high-performance thin-layer ...

Background: Antibacterial activities of crude Azadirachta indica (neem) bark and leaf extracts were investigated in bacterial species isolated from clinical samples of diabetic individuals. Methods and Material: Nine different dilutions of methanolic bark and leaf extracts were tested for this purpose in agar well diffusion method. Results: Both the extracts were active against Gram positive as...

Picea abies and Larix decidua were subjected to GC/MS analyses, and antimicrobial (fungi and bacteria) assays of their stem wood and bark extracts were investigated. L. decidua bark extract exhibited the highest antifungal and antibacterial activities against the microorganisms that were screened. The microbes Penecillium ochrochloron and Aspergillus ochraceus were the most sensitive to the ext...

Three to six hours after the administration of extracts of neem bark or flower, the blood glucose levels of normal and streptozotocin-induced diabetic mice dropped significantly. However, neem flower possesses stronger hypoglycemic activity than the bark. Hypoglycemic action of these extracts may be due to their metabolic effect on tissue and or due to increase in insulin secretion.

The leaf and bark fraction extracts of Azadirachta indica A. Juss. (neem) grown in the foothills (subtropical region) of Nepal were evaluated for their antioxidant activity, total phenolic (TP) and total flavonid (TF) contents. HPLC method was employed to quantify the amount of azadirachtin and nimbin present in the seed, leaf and the bark extracts of neem. The result showed that the highest az...

The stem bark of Carallia brachiata was studied for wound healing activity. The bark was extracted with petroleum ether, ethyl acetate and methanol successively. All the extracts were screened for wound healing activity by excision and incision models in Wistar rats. The ethyl acetate and methanol extracts were found to possess significant wound healing activity. The extracts revealed the prese...
