    Constituents from Rubia Ustulata Diels and R. Yunnanensis Diels and Their Antiplatelet Aggregation Activity[Reference: WebLink]
    A new anthraquinone glycoside, Rubiayannone A (1), and a new coumarin, rubilatin-A (2), together with twenty-two known compounds were isolated and characterized from the roots of Rubia ustulata. A new anthraquinone, 2-carbomethoxyanthraquinone (3), and rubiayannone-A, 2-formylanthraquinone were obtained from the roots of R. yunnanensis. The structures of those compounds were elucidated by spectroscopic methods. The antiplatelet aggregation activity of the isolated compounds 1, 4~6 were also discussed.
