Aims and objectives: Periodontal disease is the most common disease associated with microbial infection with destruction of supporting structures. The aim of the present study is compare the antimicrobial efficacy of plants of lythraceae family with hiora mouthwash in subjects with chronic periodontitis. Materials and methods: A total of 90 subjects were taken and randomly divided into three groups with 30 each. Group 1 received punica mouthwash, group 2 with lawsone mouth wash and group3 hiora mouth wash. Oral rinse technique was performed. Total microbial load and specific aerobic and anaerobic bacteria like Streptococci, staphylococci species, Agregatibacter actinomycetemcomitans, and Porphyromonas gingivalis were determined. Subjects were instructed to use given mouth washes twice daily with volume of 5ml/rinse for 30 sec and later post therapeutic samples were collected 1hr and 1week following drug usage and they were evaluated for total microbial load. Results: Statistical analysis was performed using chi square and one way ANOVA. All the three groups were compared at different time intervals which showed significant difference (P=0.000*) in...

The prime aim and object of present investigation is to develop and validate a novel, precise, accurate, specific, rapid and economic stability- indicating isocratic reverse phase liquid chromatography method for the quantitative simultaneous estimation of Tenofovir disoproxil fumarate and Emtricitabine in bulk and marketed formulations. Estimation of drugs in this combination was achieved with a C18 column [Agilent TC-C18 (2) column. 5mm, 4.6´250 mm]kept at ambient temperature, using mobile phase of composition Methanol and phosphate buffer (30:70 v/v, pH 4).The flow rate was 1.0 ml/min and the effluents were monitored at 261 nm, using variable wavelength UV detector. The retention time of Tenofovir disoproxil fumarate and Emtricitabine were 2.81min and 4.72min respectively. Validation of the method was done according to the ICH guidelines for different analytical parameters. The method was found to be linear over a range of 40-80mg/ml for Tenofovir disoproxil fumarate and Emtricitabine. The established method proved as reproducible one with a %RSD value of less than 2 and having the robustness and accuracy within the specified...

Today’s generic drugs manufacturing industry need robust analytical methods for analysis of generic drug products to provide best quality pharmaceutical formulation. Entacapone, Levodopa and Carbidopa tablets is such a product which is used for the treatment of Parkinson’s disease. This paper presents a robust HPLC method that has been developed for estimation of % drug release of Entacapone in this multi component drug formulation. HPLC column used for separation was Cosmosil 5PE-MS 150mm x 4.6 mm with 5 micron particle size. Combination of phosphate buffer pH 2.5, acetonitrile and methanol was used for mobile phase in isocratic mode with UV detection at 280 nm. The method was validated to ensure suitability of the method for quantitative determination of % drug release of Entacapone in presence of Levodopa and Carbidopa in this triple drug combination pharmaceutical formulation. Proposed method was found to be specific, precise, robust, accurate and linear in range 0.066 to 0.33 mg/mL of...

Staphylococcus aureus biofilm has been known as one inducing factor for the bacteria’s resistance to various antibiotics. One strategy which may increase the efficacy of the antibiotic is by combining the antibiotic therapy with antiinfective from natural resources. This research was evaluating the potency of three known antiinfective essential oil derived from leaves of Piper betle L., Ocimum basilicum L. forma citratum Back and Cymbopogon citratus L., in a combination with antibiotics i.e. chloramphenicol, streptomycin, and erythromicin towards S. aureus ATCC 29213. The essential oils were obtained by steam-hydrodistillation of the fresh raw materials. Microdillution technique combined with colorimetric was used to determine the biofilm inhibition. Crystal violet was used for biofilm staining of which the reading was performed on a microplate reader. Fractional Inhibitory Concentration Index (FICI) values was evaluated based on the comparison of % inhibitory obtained from the essential oils and the antibiotics in a single and in a combination. The essential oils alone has the PMIC50 (planktonic) values as follows, 0.2% (P. betel), 0,3% (C....

Cjanus cajan (L.) Millsp belonging to the family Fabaceae commonly known as pigeonpea or arhar. The present study conducted to assess the phytochemical and pharmacognostic in terms of organoleptic, fluorescence analysis and physicochemical parameters of seed coat and cotyledon of C. cajan. Differential extraction yielded of seed coat extracts of petether, chloroform, ethanol and aqueous shows 6.3%, 1.14%, 11.36% and 9.32% and cotyledon extracts of pet ether, chloroform, ethanol and aqueous shows 7.34 %, 4.25%, 10.45 % and 8.45 % respectively. Physicochemical parameters such as total ash, acid insoluble ash and water soluble ash of seed coat and cotyledon were found to be 14.5% and 11.5%, 8.35% and 7.36%, 2.11% and 3.39% respectively. Further the mineral elements like zinc, magnesium and copper content were found more in seed coat whereas, maximum content of iron were observed in cotyledon. The fluorescent analyses of powdered drug play an important role in the determination of quality and purity of the drug. Phytochemical analysis revealed the presence of glycosides, tannins, flavonoids, phenols, lignins,...
