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…

This review surveys chromatographic technology that has been applied to the characterization of biodiesel and its blends and primary attention is given to the determination of trace impurities in biodiesel.
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 product
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.
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-layer
Simulated Distillation Approach to the Gas Chromatographic Analysis of Feedstock and Products in the Deoxygenation of Lipids to Hydrocarbon Biofuels
This study focused on devising a method for accurately analyzing the reaction products derived from the upgrading of fats and oils to hydrocarbons. A single method capable of identifying and
Characterization and development of a method to quantify biodiesel obtained from renewable resources
Biofuels are introduced as environmentally friendly alternatives to replace fossil fuels. One of the most studied biofuels is biodiesel, which is produced from vegetable oils, animal fat, and algae
Fuel properties of B100 and blends of Terminalia belerica (Roxb.) oil biodiesel synthesised using SrO as a basic heterogeneous catalyst
ABSTRACT Terminalia belerica (Roxb.) seed oil (TBO), a non-edible feedstock with a high oil content of 32.5%, was subjected to transesterification using commercial SrO as a heterogeneous base
Gliserolisis berenzim oleh metil laurat menggunakan Lipase b Candida antarctica
Production of monolaurin was optimized based on two selected types of CALB, varying enzyme concentrations and reaction time, and characterizations were performed using different techniques namely gas chromatography-flame ionization detector, thin layer chromatography (TLC), and Fourier transform infrared spectroscopy (FTIR) analysis.


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 distilled
