shows LC–MS chromatogram for aqueous leaf extracts of Ximenia americana. The peaks represent phytocompounds with different retention times. The identities of phytocompounds were proposed based on their general fragmentation pattern and using reference spectra published by the library–MS databases of the National Institute of Standards and Technology (NIST). Twenty phytocompounds were successfully identified, including flavonoids (epicatechin, gallocatechin, quercitrin, kaempferol-G-O-arabinopyranoside, kaempferol-G-l-rhamnoside, quercetin-G-glucosyl-rhamnosyl, quercetin-3 glucoside, and quercetin-3-0-Beta-d-glucoside), tannins (gallotannin and ellagitannin), phenolic acids (protocatechuic acid, gallic acid, caffeic acid, ellagic acid, and m-coumaric acid), glycosides (quercetin-3, O-alpha-L-rhamnoside, quercetin rhamnoside, and quercetin-G-L rhamnoside), a fatty acid (tariric acid) and a phytosterol (beta-sitosterol)
