- Abstract
Kholani Coffee is a high-quality Coffea arabica cultivar in southwest Saudi Arabia. The objective of our research was to determine the phytochemical profile of the Kholani cultivar using LC-MS/MS analysis of whole coffee cherries (WCC) and coffee green beans (CGB) aqueous extract and GC-MS analysis of (CGB) nhexane extract. Additionally, well diffusion method was used to assess the antimicrobial efficacy of the extracts against six pathogenic microorganisms. LC-MS/MS analysis of water extracts produced 34 phytochemical compounds, of which 16 were identified based on previous studies; 18 were identified from Coffea arabica extracts for the first time; these compounds may be responsible for the distinctive characteristics of the Kholani cultivar. Including four compounds with high-quality separation (100%) and the following molecular formulas: C21H9N3O2S, C22H45NS4, C23H28N10O6, and C27H22N10O10. Ten phytochemicals were produced by GC-MS analysis of n-hexane extract, with varied intensities and retention times. The most significant compounds were 2-ethyl nitrobenzene and prenyl vinyl acetylene with the highest intensity. Our findings showed that all examined bacterial strains were sensitive to coffee extracts. Where (WCC) water extract was shown to have the largest inhibition zone against Proteus mirabilis. Neither Penicillium digitatum nor Aspergillus niger was sensitive to the (CGB) water extract or n-hexane. Our investigations showed that the Kholani cultivar of coffee cherries and green beans is a good source of several phytonutrients.
