摘要

The ubiquitous consumption of junk foods has drastically contributed to the exponential rise in the incidence of obesity. Hence, the present study explores the therapeutic effect of selected indigenous wild bean <i>Sphenostylis stenocarpa</i> (<i>Otili</i>) and condiment fermented <i>Parkia biglobosa</i> (<i>Iru</i>) on obese rats. The rats were fed with a high fat diet for four weeks and the gut microbiota was monitored every other day throughout the period of the experiment. Then, the fecal metabolome was analysed by Gas Chromatography Mass Spectroscopy (GC-MS). Although there was a decrease in the mean weight of rats treated with fermented <i>iru</i> compared with those given <i>Otili</i>, it was not statistically significantly (p ≤ 0.05). The organisms identified from the fecal samples of the fermented <i>Iru</i> groups are <i>Proteus vulgaris</i>, <i>Bacillus cereus</i> and <i>Esherichia coli</i> while those identified from the <i>Otili</i> group include <i>Escherichia coli</i>, and <i>Citrobacter Freundii</i>. However, further study revealed that <i>Otili</i> and <i>Iru</i> had a similar faecal metabolome. Medium chain fatty acids, such as Decanoic acid, Octanoic acid, ethyl tetradecanoate, Hexadecanoic acid, Methyl tetradecanoate, 9-Hexadecanoic acid, Hexadecnoic acid, cis-10-Hepadecanoic acid, are the most common compounds found in this study. This suggests the fact that the associated gut microbiota from breakdown of respective food samples must have actively mediated in their roles of ameliorating the effect of obesity.
