Background: Triphala is exclusively used in more than 200 drug formulations in Indian system of Medicine. The formulation process of polyherbal drugs changes the physiochemical properties of the whole drug which need to be studied and understood. Objective: The present work aims to perform the organoleptic features (color, odor, taste), and physicochemical parameters such as pH, loss on drying, ash values viz., total ash, acid insoluble ash, water-soluble ash, extractive values viz., alcohol soluble extractive and water-soluble extractive tests and were determined under variable ratio concept. Materials and Methods: The standard methods as per traditional text were followed and the physicochemical changes were also investigated. Study of individual fruit as well “under variable ratio” concept (Amla: Bahera: Harad (1:1:1), (2:1:1), (1:2:1), and (1:1:2)) of three fruits were performed. Statistical analysis was performed at significant level p ≤ 0.05. Results: The observed range of various tests were as: pH (2.5-5.9), loss on drying (4.48-13.71), total ash (2.92-10.80), acid insoluble ash (0.53-4.92), extractive values viz., alcohol soluble extractive (39.02-73.03) and water-soluble...

Nowadays, the organic way of farming gains much more important and the people believe that the production of plants with organic farming has more nutrients and a lot of health benefits. In this, the green leafy vegetables occupy an important place among the food crops as they provide an adequate number of vitamins and minerals for humans. Solanum nigrum L. and Trigonella foenum-graecum L. are commonly used leafy vegetables in South India and also have so much of medicinal uses. The present investigation aims to identify the effect of different concentration of vermicomposting and biofertilizers on the biochemical content of both leafy vegetables. A total of five experimental models were designed T0 (control) T1 (vermicompost -15gm), T2 (vermicompost -20gm) T3 (vermicompost -15gm + Azospirillum) and T4 (vermicompost -15gm + Azotobacter). Among all treatments, the vermicompost -15gm + asospirillum supplemented seedlings were absorbed significantly more protein, carbohydrates and amino acid content, whereas the chlorophyll content was recorded more in 20g of vermicompost treated seedlings of both...

Antibiotic resistance continues to pose a significant problem in the management of bacterial infections despite advances in antimicrobial chemotherapy and supportive care. Therefore, it is necessary to search the other alternatives that can be effective in the treatment of these infections. The present work was aimed to evaluate the antibacterial and antibiotic-potentiation activities of lemon against drug resistant phenotypes. The sensitivity of S. aureus and P. aeruginosa was determined by performing antibiotic sensitivity test (AST). They were found to be resistant to tested antibiotics and since S. aureus was resistant to oxacillin it was classified as methicillin resistant S. aureus (MRSA). The phytochemical analysis of lemon juice and lemon peel extract showed presence of flavonoids, phenols, steroids, reducing sugar and alkaloid. Antioxidant activity which was determined by Ferric Reducing Antioxidant Power (FRAP) assay method showed increasing trend in reducing power with the increase in concentration for both samples. The antibacterial activity of lemon juice, lemon peel extract and citric acid was screened against resistant isolates by using agar well...

The renin-angiotensin system (RAS) plays an important role in pathogenesis of hypertension, congestive heart failure, and chronic renal failure. In addition to a discussion of the current understanding of the chemical structures and the modes of action of angiotensin converting enzyme (ACE) inhibitors and angiotensin receptor (ATR) antagonists, review includes their SAR analysis and chemical modification for improving their activity. Nowadays different modeling strategies are underway to develop tailor made molecules with the best of properties among nonpeptide renin inhibitors, dual action receptor antagonists (e.g. angiotensin and endothelin antagonists, ACE/NEP inhibitors, AT1/TxA2 antagonists, balanced AT1/AT2 antagonists), triple inhibitors. In the first part is given an overview of various ACE inhibitors. The second part is devoted to overview of angiotensin receptor antagonists. The advances that have been made, new opportunities, and future directions of design and development of these classes have been...

The present study was assessed to determine the effect of various grades of phospholipids on liposomes. The various grades of synthetic phospholipids such as Phospholipon 90G® (PL90G), Phospholipon 80H® (PL80H) and Phospholipon 90H® (PL90H) were used along with cholesterol in stoichiometric ratio (1:0.25, 1:0.5, 1:1, 1:2, 1:3). Using these ratios the paclitaxel liposome was formulated by film hydration method. The prepared liposomes were assessed for characterization using entrapment efficiency, vesicular size, in vitro release and hemolytic toxicity assay. The synthetic grades of phospholipids significantly influenced paclitaxel liposomal formulations. The stoichiometric ratio (1:1) between cholesterol and various synthetic phospholipids was found to be optimized one, from rest of ratios. The characterization confirmed the formation of liposomes. The entrapment efficiency was observed to be high as increasing the ratios between cholesterol and phospholipids, but then declined suddenly as further increasing the ratio. The best liposomal formulations showed the spherical shape with size ranging from <10µm. The optimized paclitaxel liposomes % release in phosphate buffer (pH 7.4) enhanced significantly, and rest of...
