18,19-secooleanane type triterpene glycosyl esters from the bark of Terminalia arjuna.
Five novel 18,19-secooleanane-type triterpene glycosyl esters, namely arjunasides A-E, were isolated from the MeOH extract of the bark of Terminalia arjuna along with nine known oleanane triterpenoids. The structures of the new compounds were determined by spectroscopic analyses including 2D NMR, HRESIMS, and CD spectra.
