Two new malonylated oleanane-type triterpene oligoglycosides, named malonylsaikosaponins a (1) and d (2), were isolated from Bupleuri Radix, the root of Bupleurum falcatum L. Their structures were elucidated on the basis of the chemical and spectroscopic studies. Quantitative analysis of various Bupleuri Radixes by HPLC suggested that these malonylsaikosaponins are genuine saponins of this crude drug.
