In the synthesis of Nebivolol [a mixture of (1RS, 1′ RS)-1,1′-{(2RS, 2′ SR)-bis(6-fluoro 3, 4-dihydro-2H-1-benzopyran-2-yl)} -2,2′-iminodiethanol] having four chiral centers, one crucial isomeric impurity at 0.88 RRT was observed in HPLC related substance analysis in gradient HPLC method. This impurity was isolated from synthesized crude impurity substance by preparative HPLC with chiral normal phase and was elucidated as [(R)-1-[ (R)-6-Fluorochroman -2-yl]-2-({(R)-2- [(R)-6-Fluorochro man-2-yl] -2-hydroxyethyl} amino) ethanol] (R, R, R, R- Nebivolol) by means of chromatographic and spectral data. Structural elucidation carried out by spectral data was...

Antibiotic resistance emergence, as well as the Darwinism of up to the minute strains of ailment generating agents, is of grave concern to the global health community. Sustainable therapeutics of an ailment entails the amalgamation of contemporary pharmaceuticals or some potential prospective of novel drugs. Customarily employed medicative plants of Gopalganj community could be an enticing of drugs to fight this problem. This study is targeted at a reconnaissance of the antimicrobial properties of the plants that are customarily being used as traditional health implementation. The antimicrobial potential of five different plant extracts was screened against three pathogenic microorganisms, which were isolated from typical non-healing wounds of patients of Gopalganj district hospital. The microorganisms chosen to evaluate for antimicrobial activity were Proteus mirabilis, Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus. The favorable activity was shown by the extracts of Tridex procumbens L. was found to highest with zone of Inhibitions reaching to 18 mm, 19 mm and 20 they were nearly around the zone of inhibitions of positive...

Diabetes mellitus caused by inherited and/or acquired deficiency in insulin production or by the development of insulin resistance. This is chronic as well as moderately increasing day by day in developing countries as well as globally and has reached about to the epidemic ratio, and now it is a matter of worry for the populations. This deficiency results in increased blood glucose concentrations, which damages many of the body’s systems, in particular the blood vessels and nerves. There are several medications available for the disease. Worldwide, different drugs are prescribed in different manners as well as amount, which may cause severe side effects known as adverse drug reactions (ADRs). So, ADR monitoring is being an important task to reduce the damage by the drugs taken for the disease treatment. This study was performed for the ADRs monitoring of anti-diabetic medication in OPD of tertiary care hospital of northern...

Ethnomedicinal plant-like Gymnosporia montana belonging to the family Celastraceae is commonly known as Vikalo in Gujarat. Ethanomedicinally, fresh leaves of Vikalo are chewed in trible regions of Gujarat to cure jaundice. Phytochemical screening of the plant showed the presence of phytoconstituents like phenol, flavonoids, alkaloids, triterpenoids, and saponin. The present study was undertaken for Phytochemical Investigation, Isolation and Characterization of Betulin from the leaf of Gymnosporia montana. On the basis of characterization studies, the novel compound betulin was isolated by column chromatography; the isolated compound has been evaluated for its physical properties (colour, state, solubility, melting range, and Rf value), which identically resembles the standard...

This study reports the isolation and antioxidant activity of non-polar terpenes extracted from the leaves of Bougainvillea glabra choicy. To characterize the phytochemical constituents of Bougainvillea glabra leaves using the GC-MS method. The 95% ethanol extract was filtered, distilled, and concentrated to obtain the solid greenish residue. The residue was further fractioned by n-hexane, chloroform, ethyl acetate, acetone, ethanol, and methanol. The GC-MS analysis of Chloroform extract of Bougainvillea glabra leaves revealed the presence of thirteen compounds that could contribute to the medicinal quality of the plant. The first compound identified with less retention time (9.50 min) was 1-(1-methyl-decyl)-decahydro-napthalene. The isolation of organic compounds was done using column and thin layer chromatographic techniques. Compound characterization using various spectroscopic techniques identified the final isolated compound as 1-(1-methyl-decyl)-decahydronapthalene. Antioxidant activity was evaluated by the DPPH method. The method of isolation is simple, cost-effective, and...
