| dc.description.abstract | In the present study, a phytochemical investigation of two medicinal plants, namely, Acridocarpus natalitius and Typha capensis is presented. The roots of A. natalitius afforded a variety of pentacyclic triterpenoids, namely, friedelin [41], epi-friedelinol [42], lupeol [43] and oleanolic acid [44], including stigmasterol [45] from the hexane extract, whilst the methanolic extract produced a flavonoid, (-)-epicatechin [4] and carbohydrates which included glucose [64] and sucrose [65]. Two new bibenzyls were isolated from the hexane extract of the rhizhomes of T. capensis, namely, typharin [47] and typhaphthalide [48]. β-Sitosterol [49] was also isolated. The acetone extract afforded several flavan-3-ols which were isolated in their free phenolic form. These include, afzelechin [10], epiafzelechin [23], (+)catechin [11] and (-)-epicatechin [4]. A biological survey was carried out on the crude methanolic extract in an independent survey and a brief discussion is presented here. All the compounds were isolated using a series of chromatographic techniques and structures were elucidated by means of NMR spectroscopy, infrared spectroscopy and mass spectrometry. | en |
