Abstract
Five new triterpenoids, rubiarbonones D (1), E (5), and F (2), and rubiarbosides F (3) and G (4), together with nine known compounds, were isolated from the roots of Rubia yunnanensis. The structures of 1-12 were elucidated by spectroscopic methods. The antiplatelet aggregation activities of rubiarbonone A (6) and rubiarbonol A (8) and B (9) were investigated with a standard protocol.
