In this paper, we reported the isolation and structure resolution of five flavonoids including three flavan-3-ol compounds, (+)-catechin (1), (-)- catechin (2), and catechin 3- O-α-L-rhamnopyranoside (3), one flavone, chrysoeriol (4) and one flavononol, engeletin (5) from leaves of C. brachiata Merr.
