  Steroidal saponins from the rhizomes of Polygonatum odoratum

  摘要：

  Three steroidal saponins were isolated and characterised from the rhizomes of Polygonatum odoratum. The structure of the compounds were determined as 3-O--D-glucopyranosyl-(1 2)-[-D-xylopyranosyl-(1 3)]--D-glucopyranosyl-(1 4)-galactopyranosyl-25(S)-spirost-5(6)-en-3-ol (1), 3-O--D-glucopyranosyl-(1 2)-[-D-xylopyranosyl-(1 3)]--D-glucopyranosyl-(1 4)-galactopyranosyl-25(S)-spirost-5(6),14(15)-dien-3-ol (2) and 3-O--D-glucopyranosyl-(1 2)-[-D-xylopyranosyl-(1 3)]--D-glucopyranosyl-(1 4)-galactopyranosyl-25(S)-spirost-5 (6)-en-3, 14-diol (3). Compound 2 was identified as a new compound. Compounds 1-3 were found to be strong against the growth of bacteria and plant pathogenic fungi.
