Medicinal plants and natural products have many applications in the treatment of viral diseases, due to much lower side effects. Different types of hepatitis, especially hepatitis B, are of the viral diseases whose treatment using herbal medicines is currently of great interest due to the limited availability of effective chemical drugs and having numerous side effects. Due to the attention paid to herbal drugs and their importance for the treatment of hepatitis B, we conducted this review to take a look at the evidence regarding the action mechanisms of viruses, antiviral herbal remedies and various herbal anti-hepatitis drugs and their therapeutic mechanism published until 2017. To provide data for conducting this review, the most up-to-date electronic journals including those indexed in the Pubmed, Elsevier, Institute for Scientific Information, Google Scholar and Scientific Information Database databases and various books, has been used. There are several plants for the treatment of viral diseases, including hepatitis B, which prevent or decrease infection via various mechanisms. Medicinal plants counteract viruses by various mechanisms,...

Bioanalysis is a sub-discipline of analytical chemistry covering the quantitative measurement of xenobiotics (drugs and their metabolites and biological molecules in unnatural locations or concentration) and biotics (macromolecules, proteins, DNA, large molecule drugs, metabolites) in biological system. The focus of bioanalysis in the pharmaceutical industry is to provide as quantitative measure of the active drug and/or its metabolite(s) for the purpose of pharmacokinetics, toxicokinetics, bioequivalence and exposure response (pharmacokinetics / pharmacodynamics studies). Over the past several years dried matrix spot (DMS) sampling technique has emerged as a pertinent method in both qualitative and quantitative bioanalysis context. There are many types of DMS techniques such as dried blood spot (DBS), dried plasma spot (DPS), dried urine spot (DUS) and dried breast milk spot (DBMS). The most commonly used technique is DBS wherein the blood sample is directly soaked on to a paper (with or without treatment) and after drying it can be analyzed by modern analytical, immunological or genomic detection systems. Several advantages of DMS techniques such as low sample...

A LC-MS method was developed and validated for determination of ergocalciferol in human plasma. n-hexane was used as extraction solvent while kinetex C18 50*2.1 mm, 1.7µm was used as analytical column for chromatographic separation. Mobile phase was acetonitrile: 0.1% formic acid in methanol (90:10). Turbo ion spray with positive polarity was used as an interface with API QTRAP 5500 LC/MS/MS system. The calibration range was validated for 2.03 ng/mL to 150.69 ng/mL. Limit of quantification was 2.03 ng/mL. The recovery of Analyte was 97.04% to 99.27%. Labeled erythromycin was used as an internal standard for this method. Inter-batch and intra-batch accuracy and precision were calculated to check method’s performance. Stability was established for all anticipated working conditions for analyte as well as internal standard. Apart from stability experiments, other experiments were also performed to simulate the conditions of subject sample analysis. This method was applied successfully on bioequivalence study to evaluate pharmacokinetic...

The present study was conducted to investigate protective effect of hydro-methanolic (2:3) extract of leaf of Abroma augusta in streptozotocin induced diabetic male albino rat. For this purpose animals were divided into three treatment groups (n = 6): control group, STZ induced diabetic group (STZ 4 mg / 0.1 ml citrate buffer/ 100 g body weight), hydro-methanolic extract of leaf of Abroma augusta treated group (20 mg / 0.5 ml distilled water/100 g body weight). Treatment was conducted for 28 days. Blood glucose, serum insulin, glycated haemoglobin levels along with activities of hepatic carbohydrate metabolic enzymes, hexokinase and glucose-6-phosphate dehydrogenase were assed in all experimental groups. Oxidative stress markers like catalase, peroxidase enzyme activities, conjugated diene and thiobarbituric acid reactive substance levels in liver were measured. All these parameters were significantly recovered towards the control level after the treatment of hydro-methanolic extract. Pancreatic islet diameter, count of islet and number of cells in islets also decreased in diabetic animals. Treatment of these animals with extract resulted significant recovery towards...

The whole plant of Cocculus pendulus (J.R. & G. Forst.) Diels is reported to have quality medicinal values in traditional system of medicines. The various physico-chemical parameters included determination of extractive value, loss on drying, ash values, fluorescence analysis, HPTLC analysis and preliminary phytochemical analysis were performed. The preliminary identification of Cocculus pendulus was observed by studying macroscopical features and the final authentication was confirmed by the botanist. Preliminary phytochemical analysis of whole plant of Cocculus pendulus revealed the presence of various phytoconstituents like alkaloids, carbohydrates, phytosterols, saponins, proteins and mucilage. HPTLC fingerprint analysis of ethanolic extract of plant Cocculus pendulus reveals presence of 13 peaks and 10 peaks in 256 nm and 366 nm respectively. The physico-chemical evaluation of Cocculus pendulus was a useful tool to identify quality, purity and authenticity of Cocculus...
