“…Earlier phytochemical investigations of C. pentagyna from different origins have revealed the identification of different compounds such as gallic acid, caffeic acid, and chlorogenic acid in fruit, pulp and seed of Iranian species [ 15 , 16 ]; hyperoside, rutin, isoquercitrin, sexangularetin-3- O -glucoside, isoorientin, isoorientin-2- O -rhamnoside, isovitexin, orientin, orientin-2- O -rhamnoside, vitexin, and vitexin-2- O -rhamnoside in leaves of Austrian species [ 17 ]; coumaric acid, chlorogenic acid, caffeic acid, ferulic acid, quercetin 3- O -glucoside (isoquercetin), quercetin, quercetin 3- O -rutinoside (rutin), (-)-epicatechin, kaempferol 3- O- glucoside, hyperoside, apigenin, cyanidin 3- O -glucoside, luteolin and procyanidins B1 and B2 in fruits, flowers and leaves of Serbian species [ 18 ]; and a number of flavonoid aglycones, flavonoid O - and C -glycosides, organic and phenolic acids and proanthocyanidins in leaf, flower and fruit of Romanian species [ 19 ]. Previous studies showed that these phytochemicals have been linked to the health-promoting effects of this species, including cardiovascular system influence, antioxidant, anti-cancer, antimicrobial, anti-inflammatory and antihypercholesterolemic activities [ 9 , 20 ]. As an effective method with high sensitivity and resolution, liquid chromatography coupled with electrospray ionization tandem mass spectrometry (LC–ESI-MS/MS) is widely used for plant metabolomics analyses and species discrimination.…”
