High performance thin layer chromatography (HPTLC) combined with on-spot detection and characterization via easy ambient sonic-spray ionization mass spectrometry (EASI-MS) is applied to the analysis of biodiesel (B100) and biodiesel-petrodiesel blends (BX). HPTLC provides chromatographic resolution of major components whereas EASI-MS allows on-spot characterization performed directly on the HPT...

High-performance thin-layer chromatography (HPTLC)-bioassays are promising new methods for detecting bioactive chemicals in food packaging. Here, we test whether direct-acting genotoxic detectable contact materials (FCM) using HPTLC-bioassays. First, an interactive worksheet lays out steps to calculate needed detection limits (bio)analytical from regulatory limits, including thresholds of toxic...

Abstract High-performance thin-layer chromatography (HPTLC), as the modern form of TLC (thin-layer chromatography), is suitable for detecting pharmaceutically active compounds over a wide polarity range using gradient multiple development (GMD) technique. Diode-array detection (DAD) in conjunction with HPTLC can simultaneously acquire ultraviolet?visible (UV?VIS) and fluorescence spectra direct...

Six natural polyphenolic compounds, brevifolin carboxylic acid, brevifolin, ellagic acid, methyl gallate, gallic acid and protocatechuic acid have been isolated from the methanol extract of the whole plant of Erodium cicutarium (L.) L.'Hérit. (Geraniaceae). Structures were determined by conventional methods of analysis and confirmed by MS and NMR spectral analysis. The distribution of these com...

A radial "high-performance" thin-layer chromatographic (HPTLC) method is described by which the percentages and ratios of phosphatidylinositol, sphingomyelin, lecithin, phosphatidylethanolamine, phosphatidylglycerol, and dimethyl phosphatidylethanolamine may be determined simultaneously. An additional method for radial HPTLC determination of saturated phosphatidylcholine is described. We report...

BACKGROUND Over exploitation of many traditional medicinal plants like Myrica esculenta has become a threat and in the near future, many medicinal plants may be unavailable for use of industry. OBJECTIVE Present study outlines the concept of plant part substitution. Stem bark and small branches of M. esculenta are compared on the basis of physicochemical analysis, phytochemical analysis, tota...

Background: Essential oils constitute a major class of natural products. They possess various biological activities like anti-inflammatory, anti-oxidant, analgesic, and antimicrobial have immense application in food, cosmetics pharmaceutical industries. In the current study, essential were extracted from six medicinal plants including Myristica fragrans (endosperm seed or karnel mace), Illicium...
