The Antitumor Effects of Triterpenoid Saponins from the Anemone flaccida and the Underlying Mechanism

Figure 4

A model for the antitumor effects of triterpenoid saponins from the Anemone Flaccida and the underlying mechanism. TS and triterpenoid saponins 1–5 which are isolated from A. flaccida Fr. Schmidt have significant anticancer activities in cancer cell lines, and their induction on apoptosis via COX-2/PGE2 pathway is involved in the underlying mechanisms.
