| Abstract: | The aerial parts of Stevia aristata afforded in addition to known compounds two new germacranolides, a melampolide, a 4Z-melampolide and two beyerene derivatives. From the roots a new dihydrolongipinene derivative was isolated while the aerial parts of Stevia andina gave the E/Z-isomers of austroinulin and 6-desoxyaustroinulin. The absolute configuration of these typical diterpenes is discussed. |
