Abstract: Four triterpenes have been isolated from the alcoholic extract of Terminalia Chebula Retz.. Three of them have been identified as terminoic acid (T1), arjugenin (T2) and arjunolic acid(T3). T4 is a new compound, named chebupentol. Its structure was established to be olean-12-ene-2,3,19,23,28-pentol on the basis of its IR, MS, 1HNMR, 13CNMR, 1H-13C 2D NMR, 1H-1H 2D NMR and NOESY 2D NMR. The structure of compound T4 was confirmed by the chemical transformation of T4 from arjugenin (T2) with LiAlH4.

Key words: Terminalia chebula, Terminoic acid, Arjugenin, Arjunolic acid, Chebupentol
