title: Lactones and quinones from the tubers of Sinningia aggregata.
abstract: Three new aromatic epsilon-lactones, aggregatins A (1), B (2), and C (3), a new naphthoquinone derivative, aggregatin D (4), and three known anthraquinones, 2-methylanthraquinone, 7-methoxy-2-methylanthraquinone, and 7-hydroxy-2-methylanthraquinone, were isolated from the tubers of Sinningia aggregata (Gesneriaceae). Compounds 1 and 4 and the anthraquinones showed marginal antimicrobial activity.
