title: [Triterpene acids from the barks of Illicium difengpi].
abstract: Four compounds were isolated from the traditional Chinese medicine "Difengpi", barks of Illicium difengpi K.I.B. et K.I.M. They were identified as 3 beta-O-acetyl-mangiferolic acid (I), mangiferonic acid (II), mangiferolic acid (III) and butulinic acid (IV) by physico-chemical constants and spectral analyses (UV, IR, EIMS, 1HNMR, 13CNMR, NOEDE and 2D NMR). Compound I is a new compound. These triterpene acids (I-IV) were isolated from Illicium genus for the first time.
