Abstract
In continuation of our phytochemical investigation on the plant Eberhardtia aurata (Pierreex Dubard) Lecomte (Sapotaceae), the EtOAc extract of the stem bark of which showedinhibition on KB cell line, we described herein the isolation of four triterpenoids neolupenylacetate (1), betulinic acid (2), lupeol acetate (3), dammadienone (4) and one flavonoid catechin(5) . The structure was established by spectroscopic methods, including 2D NMR spectroscopy(COSY, HMQC, HMBC, NOESY).
