Thin layer chromatography (TLC) stained with hot acidic p-anisaldehyde, is an interesting, fast, and low-cost technique to monitor main lipid contaminants such as triacylglycerols, diacylglycerols, and monoacylglycerols in biodiesel. These acylglycerols are detectable by the proposed planar chromatographic method, provided the content of the contaminants exceeds the limits recommended by the international norms applicable to biodiesel quality/specification, namely 0.25% in mass for total… Expand

Determination of glyceride and free fatty acid residuals in biodiesel by thin layer chromatography combined with on-line pyrolytic methylation gas chromatography ☆
Abstract A novel method on basis of thin layer chromatography (TLC) combined with on-line pyrolytic methylation gas chromatography (OPM–GC) in the presence of trimethylsulfonium hydroxide (TMSH) wasExpand
Characterization of E 471 food emulsifiers by high-performance thin-layer chromatography-fluorescence detection.
The HPTLC-FLD approach represents a simple, rapid and convenient screening alternative to HPLC and GC analysis of the individual compounds and enables an easy characterization and the direct comparison of emulsifiers through the lipid class pattern, when utilized as a fingerprint. Expand
Lipid analysis by thin-layer chromatography--a review of the current state.
The combination betweenHPTLC and mass spectrometric (MS) detection methods will be discussed and it will be shown that this is a very powerful method to investigate the identities of the HPTLC spots in more detail than by the use of common staining methods. Expand
Production of MAG via enzymatic glycerolysis
Enzymatic glycerolysis of a medium chain methyl ester, methyl laurate was performed using lipase Candida antarctica (Novozyme 435) for 6 hours at 55°C. The percentage of components mixture of productExpand
Chemical Composition of the Lipophilic Fraction of Livistona australis R.Br. Mart., (Arecaceae ) Fruit Pulp and Evaluation of its Antioxidant and Antihyperlipidemic Activities
The lipophilic fraction of the dried pulp of Livistona australis palm fruits (LALF) was investigated for its chemical constituents using ga s chromatography-mass spectrometry (GC-MS) analysis.Expand
Methods of extraction and thin-layer chromatography determination of phospholipids in biological samples
Abstract Phospholipids (PLs) are a class of compounds essential for living organisms, including human beings. This paper presents a brief review concerning the extraction as well as thin-layerExpand

Monitoring lipase-catalyzed methanolysis of sunflower oil by reversed-phase high-performance liquid chromatography: elucidation of the mechanisms of lipases.
Individual calibration curves obtained with UV detection at 210 nm were found to be of use for quantitative analyses of double-bond containing methyl esters and acylglycerols. Expand
Technical aspects of biodiesel production by transesterification—a review
Biodiesel is gaining more and more importance as an attractive fuel due to the depleting fossil fuel resources. Chemically biodiesel is monoalkyl esters of long chain fatty acids derived fromExpand
Biodiesel production by esterification of palm fatty acid distillate
Production of fatty acid methyl ester (FAME) from palm fatty acid distillate (PFAD) having high free fatty acids (FFA) was investigated in this work. Batch esterifications of PFAD were carried out toExpand
Biodiesel from minor vegetable oils like karanja oil and nahor oil
The present study investigated the scope of two minor vegetable oils, i.e. karanja (Pongamia glabra) oil and nahor (Mesua ferrea L., Guttiferae) oil, as raw material for biodiesel fuel. The distilledExpand
Predicting the viscosity of biodiesel fuels from their fatty acid ester composition
