High Performance Thin Layer Chromatography (HPTLC) is the most simple separation technique available today which gives better precision and accuracy with extreme flexibility for various steps (stationary phase, mobile phase, development technique and detection). We planned our work as to investigate the HPTLC fingerprinting profile of alcoholic extracts of stem bark of F. bengalensis Lin. Colle...
Herbal therapy was the common treatment prescribed by Iranian physicians for wound healing. "Zemad" was the most ancient pharmaceutical dosage form used in Iranian Traditional Medicine (ITM) for skin diseases. In the present research, formulation of a traditionally used Poly Herbal Paste (PHP) for wound healing was performed. Moreover, the fingerprint of the product was prepared by HPTLC method...
AIM Detection of aflatoxin B1 in Livestock compound Feed and feed ingredients by high-performance thin layer chromatography (HPTLC). MATERIALS AND METHODS Chromatography was performed on HPTLC silica gel 60 F 254, aluminum sheets by CAMAG automatic TLC sampler 4, with mobile phase condition chloroform:acetone:water (28:4:0.06). Extraction of aflatoxin B1 from samples was done as per AOAC meth...
The separation of 9 organophosphates (monocrotophos, quinalphos, triazophos, parathion-methyl, isofenphos-methyl, temephos, parathion, phoxim-ethyl, and chlorpyrifos) by high-performance thin-layer chromatography (HPTLC) with automated multiple development was studied. The HPTLC method was developed and validated for analysis of residues of phoxim-ethyl and chlorpyrifos in tea. The sample was e...
Sphingolipids have hydrophilic and hydrophobic properties, different saturation and combination of the oligosaccharide chains and mass homology of species located in a narrow m/z region hampering their recognition. To target sphingolipids for diagnostic purposes, standardized methods for lipid extraction, quali- and quantitative assessments are required. In this study, HPTLC-MALDI MS was adopte...
Background Osteoporosis is a skeletal disorder characterised by compromised bone strength resulting in an increased risk of fracture. Although DXA the only technology that can be used for diagnostic classification osteoporosis according to WHO, computed tomography imaging (CT) densitometry spine has equal or superior ability predict vertebral fractures postmenopausal women. Therefore continued ...
Introduction: Osteoporosis is a multifactorial disease that leads to etiology leading to morbidity and economical disturbances. This study designed to evaluate the prevalence of osteoporosis in patients referred to Gorgan’s densitometry centers with respect to age, gender and BMI. Methods: In this descriptive-analytic study, from 3000 subjects referred to the densitometry centers of Gorg...
With the evolution of bone densitometry, differences in technologies, acquisition techniques, reference databases, reporting methods, diagnostic criteria and terminology have developed and the International Society for Clinical Densitometry (ISCD) periodically holds Position Development Conferences, the latest in 2007. The Brazilian Society for Clinical Densitometry (SBDens), with support from ...
Background: Polycarpaea corymbosa is one of the plants cited as ‘Parpata’ in Ayurvedic literature and indicated for boils, inflammatory swellings, and ulcers. Aim: The present study is an attempt to generate and encompass the data of physical parameters for ascertaining the identification and develop a validated HPTLC method for quantification of lupeol in P. corymbosa. Materials and Methods: T...
Plants and plant-based products are the bases of many modern pharmaceuticals that are current in use today for various diseases. The aim of the study was to investigate the biochemical constituents and high performance thin layer chromatography (HPTLC) finger printing of the ethanolic extract of Evolvulus alsinoides. Phytochemical screening was done by standard procedures and HPTLC method was a...
