Constituintes químicos de Gustavia augusta L. (Lecythidaceae)
Gustavia augusta is used in the folk medicine against leishmaniosis and showed anti-inflammatory action. The phytochemical studies of the plant stem bark have led to the isolation of (22E)-stigmasta-7,22-dien-3beta-ol, 24alpha(S)-ethyl-5alpha-colesta-7,trans-22-dien-3-one, D-friedoolean-14-en-3beta-ol, D-friedoolean-14-en-3-one and D-friedoolean-14-en-3alpha-ol along with stigmasterol, alpha-amyrin, beta-amyrin, lupeol, 3alpha-hidroxi-lupeol and betulinic acid. The structures of these compounds were identified by IR, GC/MS, ¹H and 13C NMR spectral analysis and comparison with literature data.
