| dc.description.abstract | Senna muitiglandulosa and Senna septemtrionalis are two of the eighteen Sernna species found in Ethiopia. The chloroform extract of 5. muliglanduosa leaves, after repeated chromatography, have yielded four dimeric anthranoids. Three of these were identified to be anhydrophlegmacin-9,10-quinone (61), floribundone-l (64), and torosanin-9, 10-quinone (93). The struc ture' of T-55-2, a fourth compound was partially established. From the leaves of S. septemtrionalis, the two dimeric compounds, anhydrophlegmacin-9,10-guinone (61) and torosanin-9,10-quinone (931 were isolated. To our knowledge Torosanin-g,10-quinone is reported here as a natural product for the first time, and there is only one report on the isolation of anhydrophlegmacin-9,10- quinone from higher plants. Floribundone-l was isolated earlier from both plants. | en_US |
