    Cardopatium corymbosum (L.) Pers. (Asteraceae) has been used ethnomedicinally against intestinal worms, for skin diseases, and in wound treatment. This study investigated the phytochemical profile and biological activities of ethanol (CCE), methanol (CCM), and water (CCW) extracts of C. corymbosum. LC-MS/MS analysis revealed the presence of various metabolites. Antioxidant activities of the extracts were determined by measuring 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activities and ferric-reducing power (FRAP). The cytotoxicity against human breast cancer (MCF-7) and human umbilical vein endothelial (HUVEC) cell lines were determined using the (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) (MTT) assay. Enzyme inhibitory activities against α-amylase, α-glucosidase, acetylcholinesterase (AChE), butyrylcholinesterase (BChE), thioredoxin reductase (TrxR), and elastase were measured to assess potential antidiabetic, anti-Alzheimer's, anticancer, and antiaging/wound healing effects. CCM exhibited the highest total phenolic and flavonoid contents and antioxidant activity. Fumaric acid, chlorogenic acid, vanillic acid, and rutin were identified as major components in CCM. C. corymbosum extracts, particularly those from CCE and CCM, displayed significant cytotoxicity on MCF-7 cells while exhibiting lower toxicity towards HUVEC cells. Notably, CCM demonstrated potent α-glucosidase inhibitory activity, while no α-amylase inhibition was observed. All extracts showed weak inhibition of AChE, BChE, and elastase. Conversely, the extracts displayed moderate TrxR inhibitory activity. These findings suggest that C. corymbosum possesses significant antioxidant, enzyme inhibitory, and cytotoxic potential, highlighting its promise as a source of novel bioactive molecules.
