To test the hypothesis that eastern red cedar (Juniperus virginiana L.) is allelopathic, seedling establishment of five herbaceous prairie species was evaluated by growing seeds in soil collected beneath and adjacent to a stand ofthis tree species. While four species showed no significant effect, the gennination of one species, finger coreopsis (Coreopsis pa/mata Nutt.), was significantly reduc...

Wildflowers attract wildlife, increase pollinator habitat, and enhance the aesthetic value of landscape. Wildflower establishment is increasingly part an effort to reduce maintained turfgrass on golf courses, lawns, other environments. Weed competition decreases wildflower results in poor long-term stands. Research was conducted a controlled environment investigate tolerance species common post...

OBJECTIVES This study aimed to evaluate the protective effects of total flavonoid extract from Coreopsis tinctoria Nutt. (CTF) against myocardial ischemia/reperfusion injury (MIRI) using an isolated Langendorff rat heart model. MATERIALS AND METHODS Left ventricular developed pressure (LVDP) and the maximum rate of rise and fall of LV pressure (±dp/dtmax) were recorded. Cardiac injury was ass...

The EtOAc extract of Coreopsis tinctoria Nutt. significantly inhibited LPS-induced nitric oxide (NO) production, as judged by the Griess reaction, and attenuated the LPS-induced elevation in iNOS, COX-2, IL-1β, IL-6 and TNF-α mRNA levels, as determined by quantitative real-time PCR, when incubated with BV-2 microglial cells. Immunohistochemical results showed that the EtOAc extract significantl...

Marein is the main active substance of Coreopsis tinctoria nutt. It not only has anti-oxidation and anti-tumor effects, but also can lower blood lipid, prevent high glucose, improve insulin resistance, inhibit gluconeogenesis promote glycogen synthesis. However, exact mechanism its action still unclear. Here, we explored effect on resistance. The mice were divided into db/m, db/db, metformin+db...
