title: Pyran-2-one Derivatives from the Roots of Croton crassifolius.
abstract: One new pyran-2-one derivative [crotonpyrone C (1)] and two known ones (2-3) were isolated from the supercritical fluid extract (SFE) of the roots of Croton crassifolius. Their structures were elucidated using spectroscopic (IR, UV, 1D and 2D NMR) and HRESIMS methods. The isolated compounds were evaluated for their anti-angiogenic activity using a zebrafish model, but showed little activity.
