    Author: Fokou PA, Stammler HG, Neumann B, Huber T, Lontsi D, Wangun HV, Sewald N.
    Journal: J Nat Prod; 2004 Dec; 67(12):2124-6. PubMed ID: 15620269.
    Abstract:
    Two pentacyclic triterpenes, 1alpha,3beta-dihydroxybauer-7-en-28-oic acid (1) and 3beta-hydroxybauer-7-en-28-oic acid (2), together with sitosterol-3-beta-O-d-glucopyranoside and stigmasterol have been isolated from the bark of the plant Maesopsis eminii. Their structures have been elucidated by spectroscopic methods. One of the triterpenes (1) is new, and its structure was confirmed by X-ray crystallographic analysis. This new triterpene displayed moderate antibacterial activity against Bacillus subtilis ATCC 6633.
