Application of micro-thin-layer chromatography as a simple fractionation tool for fast screening of raw extracts derived from complex biological, pharmaceutical and environmental samples

Low-parachor solvents extraction and thermostated micro-thin-layer chromatography separation for fast screening and classification of spirulina from pharmaceutical formulations and food samples

“…This work is continuation of our research focusing on development of micro-TLC platform for the fast analysis of low-molecular mass compounds from spirulina samples [55][56][57][58][59][60]. The main goal of this paper is to demonstrate the separation and detection capability of micro-TLC technique for the classification and assessment of spirulina and other selected herbal pharmaceutical and food products.…”

New approach for sensitive photothermal detection of C60 and C70 fullerenes on micro-thin-layer chromatographic plates

“…This obviously limits detection possibility of fullerenes using optical Vis images. Therefore, different detection methods for contrast increasing involving UV absorbance and fluorescence quenching have been reported [34,35].…”

“…For that reason, number of separation and detection protocols, mainly involving column chromatography, has been developed [32,33]. In the previous papers we demonstrated high ability of reversed phase micro-TLC technique for separation of low-molecular mass fullerenes, particularly C60 and C70, separated as chromatographic standards and from complex environmental samples [34,35]. In this work we propose new approach for thermovision detection and quantitative measurement of C60 and C70 fullerenes separated on micro-TLC plates with developing distance of 45 mm.…”

Temperature-controlled micro-TLC: A versatile green chemistry and fast analytical tool for separation and preliminary screening of steroids fraction from biological and environmental samples

“…This work is a continuation of our previous research focusing on development of micro-TLC methodology for fast fractionation and analysis of low-molecular mass compounds, mostly from complex samples [12,13,15,[17][18][19]. The main goal of this paper is to demonstrate the separation and detection capability of micro-TLC technique towards steroids compounds that can be present in highly loaded organic matrix extracts.…”
