Tri-spectroscopically evaluation of some selected Saudi medicinal plants for potential medical applications: UV-Visible, FTIR, and GCMS Analysis

Abstract

The unique botanical diversity of Saudi Arabia has inspired many researchers to prospect deeply in its components. Therefore, this study was designed to identify biomolecular structure of Senna italica, Cymbopogon schoenanthus, Artemisia Judaica, and flowers of Clitoria ternatea, collected from Yanbu – Radwa Mount, in the western region of Al-Madinah Al-Munawwarah – KSA. The extraction of air parts was performed by macerating in pure ethanol and stored for further investigations. UV-Vis, FTIR, and GCMS were utilized to identify the bioactive compounds of the studied plants. In comparison between samples, it was clear that the maximum peak intensity values of phenolic groups were observed in Artemisia Judaica. The highest number of amine functional groups and aromatic rings were demonstrated in Cymbopogon schoenanthus, whereas the lowest numbers are found in the Senna italica and Clitoria ternatea, respectively. This study suggested that phenyl-amino-benzoic-acid compounds detected in extracted plants may contributed to their activity.
