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...
Studies of Indigofera tinctoria Linn has shows that it possesses low toxicity. Phytochemical evaluation of leaf extract of Indigofera tinctoria Linn has been carried out to characterize some constituents present therein. Qualitative analysis of the extracts showed the presence of flavonoids, alkaloids, glycosides, terpenoids. Five compounds have been isolated from petroleum ether extract and me...
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...
Introduction: Leucas aspera (family-Lamiaceae) has great therapeutic significance in the Indian system of medicine due to its rich antioxidant activity. The main objective present work was evaluate physicochemical, phytochemical, qualitative high-performance thin layer chromatography (HPTLC), and study L. in-house mother tincture (alcoholic extract) 2 market samples reputed brands. Materials me...
Identification of 19 molecular species globotriaosylceramides (Gb3) in extracts from a Fabry's plasma patient and healthy control was performed by High-Performance Thin-Layer Chromatography (HPTLC)-densitometry online coupling to Mass Spectrometry (MS). Separation carried out on LiChrospher plates using Automated Multiple Development (AMD). Densitometry twin combining detection the visible at 5...
Advances in the applications of thin-layer chromatography (TLC) and high-performance thin-layer chromatography (HPTLC) for the separation, detection, and qualitative and quantitative determination of pesticides, other agrochemicals, and related compounds are reviewed for the period 1998-2000. Analyses are covered for a variety of samples, such as food, biological, and environmental, and for res...
The aerial parts of Cissus quadrangularis L.Variant I and II are being used therapeutically for various ailments in indigenous system of medicine. Detailed pharmacognostical studies on the aerial parts were made. Variant I and II were analysed for their physiochemical, microscopical, fluorescent, qualitative and quantitative phytochemical, TLC and HPTLC characteristics. Quantitative variations ...
