Abstract

From the ethyl acetate extract of the roots of Callerya speciosa (Champ.) Schot. collected in Vietnam, a new oleanane triterpenoid, 22β-acetoxy-3β,24-dihydroxy-12-oleanen-30-oic acid (1), along with three known compounds, medicarpin (2), maackiain (3), and β-sitosterol (4), were obtained. The structure of the new compound was elucidated by HR-MS, 1D and 2D NMR experiments.

Keywords: Callerya speciosa, oleanane triterpenoid, 22β-acetoxy-3β, 24-dihydroxy-12-oleanen-30-oic acid, maackiain (3), ethyl acetate.
