Platyconic Acid A a Genuine Triterpenoid Saponin from the Roots of Platycodon grandiflorum

摘要

A genuine triterpenoid saponin, platyconic acid A (>1) was isolated from the roots extract of Platycodon grandiflorum, together with five known saponins: deapioplatycoside E (>2), platycoside E (>3), platycodin D3 (>4), platycodin D2 (>5) and platycodin D (>6). The structure of >1 was determined on the basis of spectral analysis and chemical evidence.
