Phytochemical investigation of the stem bark of Ficus natalensis afforded eleven compounds including one ceramide (1), two anthraquinones (2, 3), four triterpenes (4–7), two polyols (8, 9) and two steroids (10, 11). The structures of the compounds were determined by spectroscopic analyses including IR, UV, MS, 1D- and 2D- NMR (¹H, ¹³C, ¹H–¹H COSY, HMQC, HMBC and NOESY), as well as by comparison with literature data. The antibacterial activity and the cytotoxicity of the extract, fractions and some isolated compounds (3, 5, 8 and 9) were evaluated. Some fractions and sub-fractions from various column chromatography displayed moderate antibacterial activity with diameter zone of inhibition (DZI) ranging from 7 to 10 mm. None of the compounds tested had activity. In the present study, all the compounds are isolated for the first time from the species F. natalensis. Compounds 2, 4–7, 10 and 11 were previously reported from the genus Ficus. The chemophenetic significance of the isolated compounds is discussed.

的茎皮的植物化学物质调查榕纳塔尔得到11个化合物，包括一个神经酰胺（1），两个蒽醌（2，3），四三萜类化合物（4 - 7），两个多元醇（8，9）和两个类固醇（10，11） 。化合物的结构通过光谱分析确定，包括IR，UV，MS，1D和2D-NMR（¹ H，¹³ C，¹ H- ¹H COSY，HMQC，HMBC和NOESY），以及与文献数据进行比较。抗菌活性和提取物，级分和一些分离的化合物（的细胞毒性3，5，8和9）进行了评价。来自各种柱色谱的某些馏分和亚馏分显示出适中的抗菌活性，其抑菌圈直径（DZI）为7至10 mm。所测试的化合物均没有活性。在本研究中，所有化合物都是首次从纳塔氏菌中分离出来。化合物2，4 - 7，10和11以前是榕属的报道。讨论了分离出的化合物在化学上的意义。
