Although invasive alien species (IAS) have a negative impact on native ecosystems and reduce ecosystem services and productivity, the understanding of IAS at the population level is still lacking. Coreopsis lanceolata, a perennial plant native to North America, is expanding its invasive range, but there is limited research on the invasion risk of this species, and measures to control its spread are inadequate. Therefore, we collected findings from selected studies on C. lanceolata, examining its morphological and growth characteristics, reproductive traits, and invasion strategies, sourced from scientific databases using its scientific name as the keyword. Researchers have conducted extensive research on C. lanceolata, primarily focusing on the extraction of chemical compounds for anticancer and antioxidant effects and numerous studies on seed germination conditions in the field of ecology. Coreopsis lanceolata has a negative impact on plant ecosystems in Australia and Japan, and its high invasiveness is associated with high seed production, high seed viability and longevity, rapid reproduction through rhizomes, high surface coverage, and long flowering periods. Few studies have examined the invasive potential of C. lanceolate and management techniques to stop its spread, despite worries about the detrimental effects of invasion on plant ecosystems. Therefore, additional research on the invasion risk and management of C. lanceolata is necessary. This review offers a thorough analysis of C. lanceolata, serving as a scientific foundation for devising future ecosystem management strategies.

The present study investigated the neuroprotective effects of Coreopsis lanceolate extract against hydrogen-peroxide (H₂O₂)-induced oxidative damage and cell death in pheochromocytoma 12 (PC12) cells. Reactive oxygen species (ROS), 2,2'-azinobis (3-ethylbebzothiazoloine-6-sulfonic acid) diammonium salt, and 1,1-diphenyl-2-picrrylhydrazyl radical scavenging activities, as well as the expression levels of proteins associated with oxidative damage and cell death were investigated. According to the results, C. lanceolate extract exhibited inhibitory activity against intracellular ROS generation and cell-damaging effects induced by hydroxyl radicals in a dose-dependent manner. Total phenolic and flavonoid contents were 22.3 mg·g^-1 gallic acid equivalent and 16.2 mg·g^-1 catechin equivalent, respectively. Additionally, a high-performance liquid chromatography (HPLC) assay based on the internal standard method used to detect phenolic compounds. The phenolic compounds identified in C. lanceolata extract contained (+)-catechin hydrate (5.0 ± 0.0 mg·g^-1), ferulic acid (1.6 ± 0.0 mg·g^-1), chlorogenic acid (1.5 ± 0.0 mg·g^-1), caffeic acid (1.2 ± 0.0 mg·g-1), naringin (0.9 ± 0.0 mg·g^-1), and p-coumaric acid (0.5 ± 0.0 mg·g^-1). C. lanceolata extract attenuated pro-apoptotic Bax expression levels and enhanced the expression levels of anti-apoptotic Bcl-2, caspase-3, and caspase-9 proteins. Therefore, C. lanceolata is a potential source of materials with neuroprotective properties against neurodegenerative disorders, such as Alzheimer's and Parkinson's diseases.
