โฆ Synopsis
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. (2), B (II), C (III) and D (IV) ond longispinogenin. Recently, Aimi and Shibota (3) and the present authors (4) independently succeeded in

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
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
