摘要：

The distribution of the naphthoquinones 7-methylijuglone and plumbagin was studied among 63 species of the Droseraceae. Both compounds occur in Drosophyllum and Drosera; only plumbagin was found in Dionaea and Aldrovanda. Within Drosera, naphthoquinones support the classifications of De Candolle and Diels to some extent, with subgenus Drosera containing sections having 7-methyljuglone, often with plumbagin, and subgenus Ergaleium containing sections where plumbagin is predominant and 7-methyljuglone rare or absent. Within subgenus Drosera, however, no naphthoquinones were found in three Australasian sections.
