BACKGROUND Nigella sativa Linn (Ranunculaceae) is popularly known as black cumin with a wide spectrum of pharmacological activities including anti-inflammatory, antibacterial, antifungal and antihelmenthic. The seeds are externally applied for eruptions of skin. The seeds are used traditionally for psoriasis tropicus with general pain and eruption of patches. OBJECTIVE The ethanolic extract o...

Aqueous and ethanolic extract of Osbeckia nepalensis Hook was evaluated for the antihyperglycemic activity in alloxan induced diabetic rats. Hyperglycemic was confirmed to Albino rats (150200 g) by treated with alloxan upto 320.6 ± 3.59 at 1 hr, 445.6 ± 4.23 at 5 days from non treated rats of 316 ± 3.56± mg/ dL. A significant hypoglycemic activity of aqueous and ethanolic extract was confirmed ...

The antioxidant action of ethanolic extract from Agaricus bisporus which is available in the supermarkets of Bucharest, Romania, was assessed by determining its reducing power and its radical scavenging activity. The determinations were made by analyzing the freeze-dried ethanolic extract. The radical scavenging activity was determined using 2, 2-diphenyl-1-picrylhydrazyl (DPPH), superoxide rad...

CONTEXT Dental caries, a ubiquitous multifactorial infectious disease, is primarily caused by microorganisms like Streptococcus mutans and Lactobacillus acidophilus. Use of antimicrobials is an important strategy to curb cariogenic microorganisms. AIM The aim was to evaluate the in vitro antimicrobial activity of C. sinensis extract on S. mutans and L. acidophilus. STUDY SETTING AND DESIGN ...

The objective of present study is to evaluate the antiulcer activity of ethanolic extract of flower of Azadirachta indica. The cause of ulceration in patients is mainly due to hyper secretion of gastric acid and pepsin. Plant extracts and polyherbal formulations are some of the most attractive sources of new drugs and have been shown to produce promising results in the treatment of gastric ulce...

The ethanol extract of Tephrosia purpurea Linn. (Family: Leguminosae) was found to significantly inhibit the carbon tetrachloride-induced lipid peroxidation in vivo and superoxide generation in vivo. The ethyl acetate fraction of the same extract was studied for free radical scavenging and antilipid peroxidation activity. The IC 50 values in both of these in vitro assays were found to be signif...

In the present study, a 50% ethanolic extract of Orthosiphon stamineus was tested for its α-glucosidase inhibitory activity. In vivo assays of the extract (containing 1.02%, 3.76%, and 3.03% of 3'hydroxy-5,6,7,4'-tetramethoxyflavone, sinensetin, and eupatorin, resp.) showed that it possessed an inhibitory activity against α-glucosidase in normal rats loaded with starch and sucrose. The results ...

Hibiscus rosasinensis flower is known as hair growth promoter in traditional and folklore medicines. Petroleum ether extract of H.rosasinensis is reported in literature for hair growth promotion. The study was aimed to investigate the efficacy of ethanolic extract of H.rosa sinensis flower as hair growth promoter. Female wistar rats were selected for hair growth promotion studies. They were div...

The aim of the study was to explore a propriety standardized ethanolic extract from leaves of Orthosiphon stamineus Benth in improving impairments in short-term social memory in vivo, possibly via blockade of adenosine A2A receptors (A2AR). The ethanolic extract of O. stamineus leaves showed significant in vitro binding activity of A2AR with 74% inhibition at 150 μg/ml and significant A2AR anta...

BACKGROUND In the present study, we tested a 50% ethanolic extract of Orthosiphon stamineus plants and its isolated bioactive compound with respect to their α-glucosidase and α-amylase inhibitory activities. METHODS Bioactive flavonoid sinensetin was isolated from 50% ethanolic extract of Orthosiphon stamineus. The structure of this pure compound was determined on the NMR data and the α-gluco...
