In this study, phytochemical investigation on the aerial parts of Bupleurum falcatum resulted in the isolation of fourteen compounds including three quinic acid derivatives (1 - 3), five flavonoids (4 - 8), three monoterpene glycosides (9 - 11), and three saikosaponins (12 - 14). Compound 1 was first isolated from nature and unambiguously determined to be 3-O-feruloyl 5-O-caffeoylquinic acid on the basis of the extensive spectroscopic evidence. Biological testing revealed that saikosaponin A (12) and saikosaponin D (13) showed moderate antiproliferative effects on HL-60 and HepG2 cancer cell lines.
