The structures of these compounds were established on the basis of spectral analyses. Other known compounds, beta -sitosterol, estigmasterol, lupeol and epilupeol, were identified in mixture by GC-MS. The triterpene esters have not shown in-vitro inhibitory effect on the growth of Leucoagaricus gongylophorus (Fisher), referred also as Leucocoprinus gongylophorus (Heim), syn Rozites gongylophora (Moller), the symbiotic fungus cultivated by the leaf-cutting ant Atta sexdens L.386-390engtriterpene esterslupanesPicramnia teapensisAtta sexdensLeucoagaricusgongylophorusArtigo10.1590/S0103-50532001000300010S0103-50532001000300010WOS:000168799700010Acesso abertoWOS000168799700010.pdf
