“…TLC on silica gel [11] developed later is based on the area of TG spot seen on the TLC in comparison to a standard and is merely qualitative and does not allow the exact determination of the degree of conversion. Bansal et al [12] recently reported a TLC method and image analysis to detect glycerol in biodiesel. This method is based on the area of the spot seen on the TLC in proportion to the amount of glycerol in the sample, followed by image analysis using the Matlab program.…”

A quantitative method is reported for the estimation of glycerol during transesterification of oil to form biodiesel. The reagent used to derivatize glycerol was 9,9-dimethoxyfluorene. Glycerol is estimated by both UV-visible spectrophotometric and high performance liquid chromatography methods. Using the former method, detection limits of 0.05% w/w of glycerol in biodiesel was established. Validation of the developed method was done using the Greenhill method for determination of free glycerol formed during the transesterification reaction.

The objective of this study is to evaluate the chemical compounds present in the Malabar tamarind seed oil. The oil was extracted from the seeds of Malabar tamarind fruits collected from NBPGR Regional station, Thrissur. The seeds yielded 46.5 % of oil. Parameters such as the peroxide value, iodine value, saponification value, and acid value of the extracted Malabar tamarind seed oil were determined. These values were used to predict the quality of fatty acid methyl esters present in the oil. UV absorption spectroscopy of the oil showed hypsochromic shift, and the maximum absorbance was at 269 nm. The Fourier Transform Infrared Spectrum revealed the presence of olefin hydrogen and carbonyl group of ester compounds in the oil sample. The evaluation of the chemical compounds in the oil using gas chromatography coupled with mass spectrometry (GC-MS) revealed that, a total of five fatty acid methyl esters were present in the oil sample. Among the five fatty acid esters present in the Malabar tamarind seed oil, Methyl 16-methyl heptadecanoate (54.57 %) was found to be the predominant compound. This study also supports the presence of olefins in the long chain fatty acids from Nuclear Magnetic Resonance (NMR) data. There is a significant correlation between the properties and the characteristic profile of the oil sample. This study is the first report that shows Malabar tamarind as a promising source of oil seeds.

“…These cultures were used as inoculum at 1.0 v/v for all experiments performed in 200-mL baffled shake flasks containing 40 mL of culture medium in a rotary shaker at 200 rpm. The effects of culture conditions and medium components on TG production were studied in the culture medium, comprising glycerol for crude glycerol, exact glycerol concentration was determined by thin layer chromatography TLC 15 as a carbon source and nitrogen source.…”
