Chemical investigation of the leaves of Bupleurum lancifolium led to the isolation and identification of two triterpenoid saponins previously undescribed named 3-O-α-L-rhamnopyranosyl (1 → 4)-β-D-glucopyranosyl echinocystic acid 28-O-β-D-glucopyranosyl ester (1) and 3-O-α-L-rhamnopyranosyl (1 → 4)-β-D-glucopyranosyl oleanolic acid 28-O-β-D-glucopyranosyl ester (2) along with the two known compounds isorhamnetin 3-rutinoside (3) and rutin (4). Their structures were elucidated by different spectroscopic methods, including HRESIMS analysis as well as 1D and 2D NMR experiments.
