Isolation, Structure Elucidation, and Cytotoxic Evaluation of Furanonaphthoquinones from in Vitro Plantlets and Cultures of Streptocarpus dunnii

“…Many Streptocarpus species are specific in their distribution and occur only in small populations, mainly in Africa. 1,2 The presence of a number of quinone metabolites in three related species of Streptocarpus, namely, S. dunnii, S. pole-eVansii, and S. dendiculatus, has been reported. 1 The major metabolites isolated from these species are furanonaphthoquinones and anthraquinones.…”
