Popis:	A new derivative of saikosaponin was isolated from the roots of Bupleurum longicaule and identified as 2''-O-β''-D-glucopyranosylsaikosaponin b2. 1 H and 13 C NMR data and the connectivities of the sugar moiety were assigned by use of a combination of two-dimensional NMR techniques (DQF-COSY, HOHAHA, ROESY, HETCOR and HMBC)
