title: Anthraquinones from Ophiorrhiza hayatana OHWI.
abstract: Three new naturally occurring anthraquinones, ophiohayatone-A (1), -B (2), and -C (3), together with four known anthraquinones, were isolated from Ophiorrhiza hayatana OHWI (Rubiaceae). Structures of these new compounds were established by spectral methods.
