Previously, we have described (1) that acid hydrolysis of the crude soponin obtained from the root of Bupleurum falcotum L. afforded saikogenins A (I), isolation of which was first reported by Shibato et al.

Recently, we have isolated saikogenins E (1, 2), F (3) and G (4) as the genuine sapogenins of the root of Bupieurum falcatum L. and demonstrated (4) that the parent saponins corresponding to these sapogenins are saikosaponins 2,~ and d (5), which on TLC using silica gel G and AcOEt-EtOH-Hz0

Most recently, Shibata et al. (1) have reported isolation of saikogenin A, a major sapogenin of the root of Bupleurum falcatum L., and proposed the partial structure (A) for it. The report prompts us to describe our result on triterpenoid sapogenins of the same saurce. Acid hydrolysis of crude sapon

We report here a successful example of organic structure determination whichrequires several steps of chemical procedure and has readily been performed using 13C NMR spectroscopy without chemical degradations. Triterpenoid glycosides, saikosaponin-a (3, -b,--b,, -c, -d (2, and -f were already isolat

From an ethereal extract of the seeds of Ilex rotunda, a new triterpene acid (Ta) has been isolated. We have named this new triterpene, rotundic acid. The crude extract was esterified with diazomethane, and the resulted. product was worked up on silica gel chromatography. This procedure yielded me

## Abstract Centrifugal partition chromatography (CPC) coupled with evaporative light scattering detection (ELSD) was applied to separate saikosaponins‐a and ‐c preparatively from __Bupleurum falcatum__ roots. The two‐phase solvent system composed of ethyl acetate/__n__‐butanol/methanol/water (15:1
