Oleanane saponins from Polyscias fruticosa.
From the leaves and roots of Polyscias fruticosa, eight new oleanolic acid saponins named polysciosides A to H were isolated together with three known saponins. The structures of the saponins were established by means of spectral data, particularly NMR, which included COSY, HSQC, HMBC, HOHAHA and ROESY techniques.
