Evaluation and Characterization of Malabar Tamarind [Garcinia cambogia (Gaertn.) Desr.] Seed Oil.

ABSTRACT: 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.

Project description:Obesity is a major global health problem which is associated with various diseases and psychological conditions. Increasing understanding of the relationship between obesity and gut microbiota has led to a worldwide effort to use microbiota as a treatment for obesity. However, several clinical trials have shown that obesity treatment with single strains of probiotics did not achieve as significant results as in animal studies. To overcome this limitation, we attempted to find a new combination that goes beyond the effects of probiotics alone by combining probiotics and a natural substance that has a stronger anti-obesity effect. In this study, we used a diet-induced obesity mouse (DIO) model to investigate the effects of combining Lactobacillus plantarum HAC03 with Garcinia cambogia extract, as compared to the effects of each substance alone. Combining L. plantarum HAC03 and G. cambogia, treatment showed a more than two-fold reduction in weight gain compared to each substance administered alone. Even though the total amount administered was kept the same as for other single experiments, the combination treatment significantly reduced biochemical markers of obesity and adipocyte size, in comparison to the treatment with either substance alone. The treatment with a combination of two substances also significantly decreased the gene expression of fatty acid synthesis (FAS, ACC, PPARγ and SREBP1c) in mesenteric adipose tissue (MAT). Furthermore, 16S rRNA gene sequencing of the fecal microbiota suggested that the combination of L. plantarum HAC03 and G. cambogia extract treatment changed the diversity of gut microbiota and altered specific bacterial taxa at the genus level (the Eubacterium coprostanoligenes group and Lachnospiraceae UCG group) and specific functions (NAD salvage pathway I and starch degradation V). Our results support that the idea that the combination of L. plantarum HAC03 and G. cambogia extract has a synergistic anti-obesity effect by restoring the composition of the gut microbiota. This combination also increases the abundance of bacteria responsible for energy metabolism, as well as the production of SCFAs and BCAAs. Furthermore, no significant adverse effects were observed during the experiment.
