Triterpenes from the roots of codonopsis pilosula

From the roots of Codonopsis pilosula (Franch) Nannf (Campanulaceae) five triterpenoids: taraxerol, taraxeryl acetate, 14-α-taraxeran-3-one and D:B-friedoolean-5-ene-3-β-ol as well as α-spinasterone were isolated. Their structures have been identified by MS, 1 H-, 13C-NMR spectroscopy and comparison with reported data.
