Abstract Phytochemical investigation on the water-soluable portions of the EtOH extracts of the flowers of Coreopsis tinctoria Nutt. led to the isolation of six flavonoids, including a new okanin glycoside. The structures of these compounds were identified by spectroscopic analysis, chemical method, and comparison with the literature.
