## Abstract Supercritical fluid extraction (SFE) was used to extract saikosaponins a, c and d from the root of __Bupleurum falcatum__. An orthogonal array design L~9~(3)^4^ was employed as a chemometric method for the optimization of the SFE conditions. The effects of four factors including pressur
## Abstract Accelerated solvent extraction (ASE) was applied to the extraction of saikosaponin a, saikosaponin c and saikosaponin d from the roots of __Bupleurum falcatum__. Main extraction parameters such as the extraction solvents, extraction temperature and static extraction time were investigat
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
## Abstract Centrifugal partition chromatography (CPC) coupled with evaporative light scattering detection (ELSD) was applied to separate saikosaponinsβa and βc preparatively from __Bupleurum falcatum__ roots. The twoβphase solvent system composed of ethyl acetate/__n__βbutanol/methanol/water (15:1
