Maytenus salicifoliaReissek (Celastraceae). The structural formula and the stereochemistry of compound 6 were established by the data obtained through 1 H and 13 C NMR spectroscopy, including HMBC, and NOESY) experiments. By analysis of the spectral data, it was possible to correct seven chemical shift assignments of compound 6, which were erroneous attributed and published in the scientific literature.Plants of the Celastraceae family comprise 90 genera and 1210 species worldwide, the majority of which are found in tropical and subtropical regions [1]. In Brazil, the members of this family are distributed in four genera: Maytenus Juss., Goupia Reiss., Austroplenckia Lund., and Franhofera Mart. [2,3].In a continuing research of bioactive metabolites from species of the Celastraceae family, we investigated the chemical constituents of the fruit pulp of Maytenus salicifolia Reissek. It is a native plant found mainly in the "cerrado" (Savanna) of the states of Bahia, Minas Gerais, and Rio de Janeiro, Brazil. The leaves of this species have been used in traditional medicine for the treatment of stomach ulcers. The decoction of the leaves made together with other parts of the plant is also traditionally used in the form of a bath to alleviate symptoms of itches and allergies [4]. The pentacyclic triterpenes (PCTTs) 3E-stearyloxyursan-12-ene, friedelin, E-friedelinol, D-amyrin, E-amyrin, and lupeol were previously isolated from the leaves of M. salicifolia by Miranda et al. [5]. PCTTs of the series friedelane, oleanane, ursane, lupane, and others are compounds that are frequently isolated from other species of the Celastraceae family [5]. Sesquiterpenes [6,7], alkaloids and flavonoids [8], proanthocyanidins, and glycosylated steroids [9] are also commonly isolated. Pharmacological properties such as anti-inflammatory [10], antitumor [11], and anti-AIDS [12] have been presented for some of these PCTTs compounds. Then, the presence of PCTTs in Celastraceae species or in other plants confers to it an important chemical and therapeutic potential. The traditional medicinal use of M. salicifolia and its pharmacological potential induces us to study the phytochemical properties of different parts of this plant, including the pulp fruit. Generally, phytochemical studies of the fruit pulp of Celastraceae species lead to the isolation of sesquiterpenes [13,14] and alkaloids [15]; nevertheless, the presence of PCTTs in this part of the plant is relatively rare.
