Description
Summary:<abstract language="eng">Phytochemical investigation from the stems of Spathelia excelsa (Rutaceae) collected in Amazonas yielded deacetylspathelin (1), 7,8-dimethoxyflindersine (2), new glabretal-type triterpenoid 3&#946;-angeloyl-21,24-epoxy-7&#945;, 21&#945;, 23&#945;, 25-tetrahydroxy-4&#945;, 4&#946;, 8&#946;, 10&#946;-tetramethyl-25-dimethyl-14, 18-cyclo-5&#945;, 13&#945;, 14&#945;, 17&#945;-cholestane (3), in addition to the known steroids &#946;-sitosterol and stigmasterol. Their structures were established on the basis of spectral data. The compounds 1 and 3 were assayed on Aedes aegypti (larvicidal and adulticidal activities and compound 3 exhibited larvicidal properties with LC50 of 4,8 µg/mL.
