Cough is the most common symptom of respiratory diseases. When cough becomes serious, opioids are effective, but they have side effects like sedation, constipation. Therefore, there is a need to have effective antitussive agent which do not have respiratory depressant activity. The present study was carried out to evaluate antitussive activity of Glycyrrhiza glabra and Adhatoda vasica using a cough model induced by sulphur dioxide gas in mice. The effect of the ethanol extracts of Glycyrrhiza glabra and Adhatoda vasica on SO2 gas induced cough in experimental animals have very significant effects at the level of p<0.01 in inhibiting the cough reflex at a dose of 800 mg/kg and 200 mg/kg body wt. p.o., in comparison with the control group. Mice showed an inhibition of 35.62%, in cough on treatment with Glycyrrhiza glabra and 43.02% inhibitionon treatment withAdhatoda vasica within 60 min of the experiment. The antitussive activity of the extract was comparable to that of codeine sulphate (10, 15, 20 mg/kg body wt.), a standard anti-tussive agent. Codeine...

Obesity is one of the main public health problems in developed countries. It is considered to be a risk factor associated with the genesis or development of major chronic diseases, including cardiovascular disease, diabetes, and cancer. Many botanicals may provide safe, natural, and cost-effective alternatives to synthetic drugs. The results of this study show promise for the potential use of these plant materials as a lipase inhibitor in the treatment of obesity. The present study tested the hypothesis that the selected herbs/extracts can inhibit the enzymatic activity of LPL in vitro. Based on the literature review Camellia sinensis leaves was selected for the present study. Methanolic (MCS) and aqueous (ACS) extracts of Camellia sinensis leaves were prepared by soxhlet and hot reflux extraction methods respectively. These extracts were then examined for their in-vitro lipase inhibitory activity at a concentration level of 0.5, 1 and 2 g/l and their percentage inhibitory effect were reported and statistically analyzed. Results of the in-vitro lipase activity reveals that percentage inhibition of MCS was...

Flavonoids have been reported to have many pharmacological activities, antimicrobial, antioxidant, cytotoxic, chemoprevention activities along with strong antiproliferative effects. The fruits of Garcinia lancaefolia Roxb., family Cluseaceae , a plant endemic to Assam has been used in locally to treat many diseases for which it was selected for investigationg its antimicrobial properties. No scientific validation has been made so far on its phytochemical content and the antibacterial activity for which the methanolic and water extract of plant parts were investigated by Agar Well Diffusion method. Furthermore, our phytochemical studies indicated that methanolic extract of Garcinia lancaefolia flowers and fruits contains flavonoids, tannins, reducing sugar, steroid terpene and cardiac glycosides. The total phenolic and flavonoids content studies were quantified for all the plant parts. Antibacterial activities of the crude extract were screened against wound infection causing 5 human pathogens. The most susceptible bacteria were S. aureus, followed by beta hemolytic Streptococcus pyogens, while the most resistant bacteria were E. coli, followed by Bacillus subtilis. From the screening experiment, the crude...

Telosma africanum (N.E.Br) Colville (Ascelpiadaceae) is a slender riverine and deciduous climber used traditionally in the treatment of venereal diseases. Using standard procedures, the pharmacognostic studies, fluorescence analysis and phytochemical screening were carried out. This study revealed the presence of combined Anthraquinone, Saponin, Cardiac glycoside, alkaloids in the leaf and stem. Flavonoid as well as uniseriate trichomes and anisocytic type of stomata were present in the...

Most of the therapeutic agents are recommended through an oral route, but oral route has disadvantages like first pass metabolism, liver toxicity, etc, due to gastrointestinal pH. This leads poor bioavailability of drugs, which are not stable in G.I pH. To overcome this problem, increase the bioiavailibility, reduce the dose and dose dumping Transdermal delivery system is better option as novel drug delivery system, which bypass the hepatic first pass metabolism, and avoid drug degradation due to systemic absorption of the drug. Minimize plasma level fluctuations and extend the drug activity besides improving patient compliance. Sumatriptan succinate is a selective 5-hydroxytryptamine receptor subtype agonist. Sumatriptan succinate is chemically designated as 3-[2-(dimethylamino)ethyl]-N-methyl-indole-5-methanesulfonamide succinate. Sumatriptan succinate is a white to off-white powder that is readily soluble in water. Oral administration of Sumatriptan succinate suffers from poorbioavailability, partly due to presystemic metabolism- some of it gets broken down in the stomach and bloodstream before it reaches the target arteries. Sumatriptan is metabolized primarily by monoamine oxidase A into an indole acetic acid...
