shows LC–MS chromatogram for aqueous leaf extracts of Pappea capensis. The peaks represent phytocompounds with different retention times. The identities 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-four phytocompounds were successfully identified, including flavonoids (hesperidin, quercitrin, epicatechin, myricetin, quercetin-3 glucoside, rhamnetin, kaempferol-3-0-arabinopyranoside, quercetin-3-O-beta-arabinopyranosyl, quercetin-3-O-beta-D-L-glucosyl, quercetin-3-O-beta-D-L-glucoside and quercetin-3-O-beta-D-G-glucoside), glycosides (quercetin rhamnoside, kaempferol hexoside and quercetin-3-0-alpha-L-rhamnoside), and phenolic acids (protocatechuic acid, gallic acid, caffeic acid, p-coumaric acid, ferulic acid, 3,4,5,trimethoxycinnamic acid, ellagic acid, chlorogenic acid, gentisic acid and isoferulic acid)
