| Abstract: | Three new vismiones and 3-geranyloxy-6-methyl-1,8-dihydroxyanthraquinone were isolated from the berries of Psorospermum febrifugum together with the known chrysophanic acid, 2-isoprenylemodin and ferruginin B. Their structures were established through chemical and spectral means. The occurrence of prenylated anthracenes only in Vismieae suggests their use as systematic markers for the tribe. |
