Platycodin D2 , a less hemolytic saponin, can improve specific cellular and humoral responses to hepatitis B surface antigen in mice, it could be safely used as adjuvant eliciting Th1 and Th2 immune responses. Polygalacin D2 has anti-cancer activity, it exhibits significant inhibition on the proliferation of five kinds of cultured human tumor cell lines.

ChEBI: Platycodin D2 is a triterpenoid saponin. It has a role as a metabolite.

Platycodin D2 is a saponin isolated from Platycodon grandiflorum, with anti-cancer activity.

A novel triterpenoid saponin, deapioplatycoside Ewas isolated from the root extract of Platycodon grandiflorum, together with the seven known saponins 2 - 8, i. e., platycoside E, deapioplatycodin D3 , platycodin D3, polygalacin D2, Platycodin D2 , deapioplatycodin D and platycodin D. The structure of the new saponin 1 was determined on the basis of spectral analysis and chemical evidence.
