O estudo fitoquimico das folhas de Maytenus distichophylla Mart. ex Reissek levou ao isolamento de um novo triterpeno 3,16,21-trioxo-6β,12α-dihidroxi-1-en-friedelano, nomeado maytensifolona, juntamente com os triterpenos conhecidos, 3-oxofriedelano, 3,12-dioxofriedelano, 3β-hidroxifriedelano, 3-oxo-29-hidroxifriedelano, 3-oxo-12α-hidroxifriedelano e 3-oxo30-hidroxifriedelano. A identificacao estrutural foi baseada em metodos espectroscopicos e comparacao com dados da literatura Phytochemical study of the leaves of Maytenus distichophylla Mart. ex Reissek led to the isolation of the new triterpene 3,16,21-trioxo-6β,12α-dihydroxy-1-en-friedelane, named maytensifolone, along with the known triterpenes 3-oxofriedelane, 3,12-dioxofriedelane, 3β-hydroxyfriedelane, 3-oxo-29-hydroxyfriedelane, 3-oxo-12α-hydroxyfriedelane and 3-oxo30-hydroxyfriedelane. Their structural identification was based on spectroscopic methods and comparison with literature data.
