Abstract: | The volatile oil and the methanol extract from the leaves of Guarea guidonia, Meliaceae, were individually submitted to chromatographic separation. A sesquiterpene (2S*)-eudesma-5,7-dien-2-ol, together with six known ones, were isolated from the volatile oil. The methanolic extract afforded two known and two new triterpenes (23S*)-cycloart-24-ene-3β,23-diol and (23R*)-cycloart-24-ene-3β,23-diol, besides three known sesquiterpenes, one known diterpene and two steroids. Their structures were established on the basis of spectrocopic data, mainly by 1H and 13C NMR spectroscopic analyses. |
