Abstract (Summary)

This study aimed to qualitatively identify the presence of saponins in Colubrina arborescens bark extract. Known as the Mauby tree in native tropical countries, the bark is brewed to create a beverage that is utilized as a folk remedy; however, there is a dearth of existing research on its physiological benefits to humans. Prior research shows the beneficial effects of saponins on cardiovascular disease, cancer, diabetes mellitus, and inflammation. Using a foam/froth test, the physical presence of saponins was positively verified in the Mauby extracts. Additionally, using qualifier ion percentages, gas chromatography (GC)— mass spectrometry (MS) potentially identified three phytosterol saponin precursors (i.e., campesterol [99%, 96%], stigmasterol [97%, 92%], and sitosterol [undetected, 99%]) and two triterpenoid saponins (i.e., taraxasterol [70%,] and lanosterol [64%, 62%]) in undiluted and diluted samples, respectively. Consequently, future research is necessary to further verify the identities and quantify the saponins potentially identified in the Mauby bark.
