    Journal: J Asian Nat Prod Res; 2013; 15(10):1123-9. PubMed ID: 23869599.
    Abstract:
    A new triterpenoid saponin, named 3-O-β-d-glucopyranosyl-(1 → 3)-β-d-xylopyranosyl-(1 → 2)-[α-l-rhamnopyranosyl-(1 → 3)]-β-d-glucopyranosyl-(1 → 4)-[β-d-glucopyranosyl-(1 → 2)]-α-l-arabinopyranosyl-3β,16α,28,30-tetrahydroxy-olean-12-ene (1), along with four known triterpenoids (2-5), was isolated from the rhizomes of Ardisia gigantifolia. Their structures were elucidated by spectroscopic methods. Compounds 1-4 showed cytotoxic activity against Hela, EJ, BCG, and HepG-2 cell lines. The percentage of early apoptotic cells after treatment with 1 was significantly increased compared with control cells (p < 0.05).
