What are the morphological characteristics of this plant?
Coreopsis lanceolata has lanceolate, entire leaves that are typically 2 to 8 centimeters long and arranged alternately along a stem that reaches heights of 10 to 40 centimeters. The plant features composite flower heads characterized by bright yellow ray florets surrounding a central disk of darker yellow tubular florets. These floral structures are supported by stalks that emerge from a basal rosette of foliage. The foliage is often somewhat fleshy or thickened, reflecting its adaptation to specific soil conditions. Small, inconspicuous bracts are positioned beneath each flower head to provide structural support.
What is the geographical distribution of this plant?
This plant is native to the central and southeastern United States, ranging from Texas in the west to North Carolina in the east and extending north toward Missouri and Nebraska. It primarily populates open prairies, rocky slopes, and disturbed sites throughout the Great Plains and the Southeast. Individual populations are often found in well-drained soils across various states including Oklahoma, Arkansas, and Tennessee. This species thrives in sunlight-rich environments within these specific regional territories. Its distribution patterns are closely tied to the grassland and woodland edge habitats found across these midwestern and southern landscapes.
How is this plant cultivated?
This plant thrives in full sun and well-drained soil within USDA hardiness zones 4 through 9.
It is a drought-tolerant perennial that requires minimal supplemental watering once its root system is established. To maintain healthy growth, provide locations with sandy or rocky substrates to prevent moisture retention. You should remove dead flower heads throughout the summer to encourage continuous blooming.
Pruning the foliage back in early spring helps stimulate fresh growth for the new season.
What parts of this plant are used medicinally?
This plant medicinal uses involve the whole plant, including the flower, leaves, and stems. The yellow flower heads are often collected for their potential properties in traditional remedies. Some herbalists utilize the entire herb to prepare infusions or topical applications. These preparations are sometimes believed to assist with skin ailments or digestive concerns. Careful identification is necessary before using any part of the species for health purposes.
According to a study published by "Bioorganic & medicinal chemistry letters", the yellow flowers of the perennial plant Coreopsis lanceolata were investigated for their medicinal potential. The total flavonoid content in the EtOAc fraction of the flower methanol extract was found to be 420mg/g. These flowers showed the inhibition of cell proliferation and the possible induction of apoptosis in human leukemia HL-60 cells. Phytochemical research led to the isolation of rare flavonoids such as a flavanone, chalcones, and aurones. Specifically, 4-methoxylanceoletin demonstrated potent antiproliferative activity.

What traditional systems uses this plant?
This plant, known as lanceleaf coreopsis, was historically utilized by various Native American tribes for its medicinal properties, specifically as a remedy for skin ailments and digestive issues.
Indigenous groups often prepared infusions or decoctions from the plant to treat minor wounds and inflammations. Some traditions also involved using the foliage to alleviate stomach discomfort or as a topical wash for irritations. Beyond its medicinal applications, the plant held ecological significance within the traditional landscapes managed by these communities.
These historical practices reflect a deep understanding of local botanical resources for maintaining community health.
What are the pharmacological activities of Coreopsis lanceolata?
This plant has demonstrated significant pharmacological potential through its anti-apoptotic, anti-diabetic, anti-oxidant, anti-leukemic, and antiproliferative activities. Its antioxidant properties help neutralize harmful free radicals, thereby reducing oxidative stress within biological systems. The plant also exhibits antiproliferative and anti-leukemic effects, which are crucial for inhibiting the uncontrolled growth of malignant cells. Furthermore, its anti-apoptotic mechanisms can influence programmed cell death pathways in various disease models. These combined therapeutic actions suggest that Coreopsis lanceolata could serve as a valuable source for developing new medicinal treatments.
According to a study published by "Antioxidants (Basel, Switzerland)", Coreopsis lanceolata L. flower extracts, specifically the 70% ethanol extract known as CLF1 and the water extract known as CLF2, contain 10 types of phenolic compounds. In vitro studies showed that CLF ameliorated H2O2-induced oxidative stress and induced the expression of antioxidant enzymes in PC12 cells. The CLF1 extract enhanced the expression of the Bcl-xL protein while reducing the expression of Bax and the cleavage of caspase-3. In vivo, pretreatment with 200 mg/kg of CLF1 increased the Bcl-2 protein and decreased Bax in a C57BL/6 mice model. These results suggest that CLF1 exerts neuroprotective effects against oxidative stress-induced apoptosis by regulating the expression of the Bcl-2 family.
The primary pharmacological activities of this plant are shown in the list below.
- anti-apoptotic
- anti-oxidant
- antiproliferative
- neuroprotective
- pro-inflammatoty inhibition
What medicinal compounds this plant contains?
This plant contains the medicinal compounds 4-methoxylanceoletin, astragalin, aurones, flavonoids, and leptosin. These specific chemical constituents contribute to the biological activities and potential therapeutic properties of the species. The presence of flavonoids and aurones suggests that the plant possesses significant antioxidant capabilities. Additionally, specialized compounds like 4-methoxylanceoletin and leptosin are characteristic of its unique chemical profile. Astragalin further enhances the complex phytochemical makeup found within its tissues.
According to a study published by "Molecules (Basel, Switzerland)", Coreopsis lanceolata flowers contain high flavonoid structure content including two aurones and two flavonols. The four identified flavonoids are leptosidin (1), leptosin (2), isoqueracetin (3), and astragalin (4). High-performance liquid chromatography analysis of the MeOH extract determined the content levels of these compounds to be 2.8 ± 0.3 mg/g for 1, 17.9 ± 0.9 mg/g for 2, 3.0 ± 0.2 mg/g for 3, and 10.9 ± 0.9 mg/g for 4. These compounds showed radical scavenging activities and recovery activities in Caco-2, RAW264.7, PC-12, and HepG2 cells. Additionally, the MeOH extract, EtOAc fraction, and compounds 1-3 suppressed NO formation in LPS-stimulated RAW 264.7 cells. All four compounds also recovered pancreatic islets damaged by alloxan treatment in zebrafish.
