A new dammarane-type triterpenoid saponin, (20R)-ginsenoside ST(2) (1), along with five known saponins was isolated from the hongshen extract of Shenmai injection. The structure of 1 was elucidated to be (20R)-dammar-23(E)-ene-3β,6α,12β,20,25-pentol 6-O-β-D-glucopyranoside by means of spectroscopic methods.
