Endophytic actinomycetes are the potential source for obtaining novel bioactive compounds. Present study evaluates the chemical constituents in Ocimum basillicum and its endophytic actinomycetes. Eleven endophytic actinomycetes were isolated from O. basillicum plant. Among eleven, one isolate was characterized by 16S rRNA and identified as Streptomyces flavoviridis A3WK. A comparative analysis of the FT-IR, GC-MS, antibacterial, antioxidant and anti-inflammatory properties of plant and endophytic actinomycetes extracts was conducted. 12 compounds each of Streptomyces flavoviridis A3WK and O. basillicum were identified by GC-MS. The FT-IR and GC-MS analysis reveals that S. flavoviridis A3WK has more antimicrobial, antioxidant activity and anti-inflammatory properties compared with the results of O. basillicum. Over all the activity of the endophytic actinomycetes was more compared to that of the O. basillicum extracts. The study reveals to show that the existence of endophytic actinomycetes may enhances medicinal value of the medicinal plants, and hence such studies help in the study of endophytic actinomycetes as well as their relevance in host...

Ephedra gerardiana is an important medicinal plant used as Somalata in Indian Ayurvedic system of medicine and as traditional Chinese medicine since several thousand years. Plant is known to contain valuable secondary metabolite such as ephedrine and pseudo ephedrine. These secondary metabolites are utilized for several medicinal purposes. The present study describes the in vitro regeneration of Ephedra gerardiana using tissue culture technique. Experiments were conducted to study the effect of various combinations of auxins (IBA) and cytokinins (BAP) alone or in different combinations on in vitro culture of nodal segments. Shoot induction and elongation from cultured nodal segments were obtained onto MS medium supplemented with various concentrations of BAP and 15 µM Kinetin. MS+IBA media was utilized for in vitro root induction. Among different media combinations utilized MS+ 5 µM BAP+ 15 µM kinetin was found best for shooting and ¼ MS+ 20 µM IBA was most appropriate for...

A spectrophotometric and reverse phase high performance liquid chromatography methods has been developed for the estimation of Ranolazine in bulk and pharmaceutical dosage form. For UV spectrophotometric method Ranolazine shows maximum absorbance at 273 nm with the concentration ranges of 20-150 µg/mL. The detection limit and quantification limit were found to be 1.23 and 5.21 µg/mL, respectively. Accuracy was in the range of 99.8-100.2%. Intraday and interday precision was in the range 0.16- 0.38% and 0.50-0.82% respectively. The RP-HPLC separation was achieved by using Phenomenex Gemini C18 (100mm X 4.6mm), 3μm column and buffer: acetonitrile (60:40, v/v), (1.0 mL of triethylamine in 1000 mL milli- Q water, pH adjusted to 6 using dilute o-phosphoric acid solution) as mobile phase. The flow rate was 1.0 mL/min and effluents were monitored at 224 nm. The retention time was 5.08 min. The linearity was in the range of 20-150 µg/mL. The detection limit and quantification limit were found to be 1 and 4 µg/mL, respectively. Accuracy was in the range of 99.9-100.1%....

The Pharmacological effects of silver nanoparaticle of Stemodia viscosa aqueous plant extract on albino wistar rats was explored. The plant extract 40 ml was added to 10 ml of 10mM silver nitrate aqueous solution and kept at room temperature for synthesizing silver nanoparaticle. Diabetes was induced in overnight fasted mice by single intra-peritoneal injection of 55 mg/kg of Streptozotozin (STZ), freshly dissolved in 0.1M cold citrate buffer, pH 4.5. After five days of STZ administration, blood was collected and plasma glucose levels were determined. For wound healing activity, a control ointment base was formulated without any drug content. Two creams were formulated by using 5% extract were incorporated in 100gm of cream base. The observation of the percentage wound contraction were made on 4th , 8th , 12th , 16th and 22nd day of post wounding days. All the values were statistically analyzed by unpaired student test comparing with control. The administrations of plant extract to STZ induce diabetic mice, significantly lowered the plasma glucose level as compared to...

Benzimidazole is a heterocyclic aromatic organic compound which has been an important pharmacophore and privileged structure in medicinal chemistry. Substituted benzimidazoles have considerable interest as compounds with a wide spectrum of biological activity and low toxicity. In the present study, a new series of benzimidazole thiourea derivatives are synthesize and screened for antibacterial and antifungal activity. The Methyl 4-(1H-benzo[d]imidazol-2-yl) phenyl carbamodithioate amine derived from Methyl 4-(1H-benzo[d]imidazol-2-yl) phenyl carbamodithioate (TD1-TD6) have been synthesized by reacting the thio methyl group with different amines in presence of ethanol. The synthesized compounds were characterized by FT-IR, 1H NMR, Mass spectra and elemental analysis. The synthesized compounds were screened for their in vitro growth inhibiting activity against four bacterial strains Bacillus subtilis, Staphylococcus aureus (Gram positive bacteria); Escherichia coli, Pseudomonas aureginosa (Gram negative bacteria) and two fungal strains namely Candida albicans and Asperginous niger. The synthesize compounds were compared with standard agents norfloxacin for antibacterial and fluconazole for antifungal activity using well plate method. Compounds exhibit good activity in bacteria Bacillus subtilis and fungous...
