Abstract
Two new benzoic acid esters of triterpene alcohols [lup-20 (29)-en-28-oic a cid 3 alpha, 7 beta -dibenzoate and 3 alpha -hydroxy-lup-20(29)-en-28-ic ac id 7 beta -benzoate] were isolated from the stem bark of Picramnia teapensi s Tul. The structures of these compounds were established on the basis of s pectral analyses. Other known compounds, beta -sitosterol, estigmasterol, l upeol and epilupeol, were identified in mixture by GC-MS. The triterpene es ters have not shown in-vitro inhibitory effect on the growth of Leucoagaric us gongylophorus (Fisher), referred also as Leucocoprinus gongylophorus (He im), syn Rozites gongylophora (Moller), the symbiotic fungus cultivated by the leaf-cutting ant Atta sexdens L.
