A phytochemical investigation of Acridocarpus Natalitius and Typha Capensis.
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 , epi-friedelinol , lupeol  and oleanolic acid , including stigmasterol  from the hexane extract, whilst the methanolic extract produced a flavonoid, (-)-epicatechin  and carbohydrates which included glucose  and sucrose . Two new bibenzyls were isolated from the hexane extract of the rhizhomes of T. capensis, namely, typharin  and typhaphthalide . β-Sitosterol  was also isolated. The acetone extract afforded several flavan-3-ols which were isolated in their free phenolic form. These include, afzelechin , epiafzelechin , (+)catechin  and (-)-epicatechin . 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.
