In the present study, the antimicrobial efficacy of acetone, methanol and water extracts of leaf, stem bark and fruit of Elaeocarpus tuberculatus Roxb. (Elaeocarpaceae) were examined against four bacterial species (Shigella sonnei, Salmonella typhi, Staphylococcus aureus and Klebsiella pneumoniae) and a fungal species (Candida albicans) using the agar well diffusion method. Results showed that ...

Ailanthus excelsa (Stem bark) are used in folk medicine for a treatment of inflammation, arthritis, expectorant, stimulant and asthma. Acute toxicity study of A. excelsa stem bark was performed on mice (Swiss) and albino rats (Wistar strain),given single doses 1,10, 50, 100 ,1000 and 2000mg/kg,po. showed normal behavior and no mortality up to 14 days except 500,1000 and 2000mg/kg dose 20%, 60.0...

The methanol extracts of Sphenocentrum Jollyanum organs were assessed for their anti-oxidant and anti-angiogenic activities using DPPH and CAM assays respectively. The results indicated the stem bark as the most active organ with an IC50 of 1.80 ± 0.25 and 1.00 ± 0.20 score (at 500 μg/pellet) on DDPH and anti-angiogenesis assays respectively. Further fractionation of the stem bark revealed the ...

The effect of sub-lethal doses (40% and 80% of LC(50)/24h) of plant derived molluscicides of singly, binary (1:1) and tertiary (1:1:1) combinations of the Rutin, Ellagic acid, Betulin and taraxerol with J. gossypifolia latex, leaf and stem bark powder extracts and their active component on the reproduction of freshwater snail Lymnaea acuminata have been studied. It was observed that the J. goss...

Diabetes mellitus type 2 is a metabolic disorder characterized by hyperglycemia including insulin resistance and relative lack of insulin. Type 2 diabetes is expected to reduce ten-year-shorter life expectancy. In this research article, we have isolated two terpenoids from the stem bark of Syzygium alternifoliumby column chromatography.The isolated compounds were identified as friedelin and 3β-...

Dried stem bark extracts of Saraca asoca Roxb. Prepared by different extraction methods (Soxhlet, Ultrasonication assisted & Microwave assisted extraction) with ethanol 90%, ethanol 60% and acetone. The acetone extract prepared by Ultrasonication assisted extraction, showed significant antidiarrhoeal property in castor-oil induced diarrhoea in albino rats at a dose of 200 mg/kg, b.w. as compare...

The volatile oil from the stem bark of Scutia buxifolia (Rhamnaceae) has been obtained by hydrodistillation and analyzed by GC-MS. Twenty-one components were identified representing 99.93 % of the total oil composition, spathulenol (35.87%), β-cubebene (17.26%), germacrene D (6.43%), linalool (5.19%), carvacrol (4.05%) were the main components of S. buxifolia essential oil. Antioxidant and anti...

Stem bark of Nyctanthes arbor-tristis Linn. was extracted in methanol to evaluate their analgesic and anti-inflammatory activities. The analgesic activity was determined on Wistar albino rats by hot plate method, tail flick assay, and tail immersion method using Morphine sulphate as standard drug at a dose of 5 mg/kg of body weight and the results were expressed as mean increase in latency afte...

Acacia jacquemontii was assessed for active principles to ascertain the rationale for its use in traditional medicine. Preliminary phytochemical screening of the stem bark extracts showed that it possessed the active principles alkaloids, glycosides, saponins, terpenoids and tannins. The antimicrobial activity of the extracts was assayed against pathogenic strains of Bacillus cereus, Bacillus p...
