NEW TRITERPENOIDS FROM PUERARIA PEDUNCULARIS

    Abstract
  • AIM: To investigate the chemical constituents of the herbs of Pueraria peduncularis Grah. METHODS: Column chromatography were used to separate the chemical constituents. MS, IR, 1HNMR, 13CNMR(DEPT), HMQC, HMBC and NOESY were used to determine the structures of the isolated constituents. RESULTS: Three pentacyclic triterpenoids were elucidated as 3β,15α,23-trihydroxy-olean-12-en-16-one (1), 3β,15α-dihydroxy-olean-12-en-16-one (2) and 3β,22β,24-trihydroxy-olean-12-ene (soyasapogenol B, 3) on the basis of spectral evidence. CONCLUSION: Compounds 1 and 2 are new compounds.
