Leptosin is an aurone glycoside first reported from the leaves of Flemingia strobilifera, commonly known as kusrunt. Leptosin has also been found in Coreopsis species, including Coreopsis lanceolata and Coreopsis grandiflora. Another accepted name for this chemical is leptosidin 7-O-β-D-glucopyranoside. Leptosperin was originally called Leptosin before being renamed to the name it has now.
Research In a 2021 study, Leptosin was isolated from Coreopsis lanceolata flowers and was found to have antioxidant activity. Leptosin was then tested in zebrafish and the results suggested that the chemical may have potential in diabetes-related research.
