Chemical investigation of the tubers of Sinningia allagophylla led to the isolation of two new chromenes, (2S)-12-hydroxylapachenole (1) and (3R)-3,4-dihydro-3-hydroxy-4-oxo-8-methoxylapachenole (2), and three new dimeric chromenes, allagophylldimers A–C (3–5). Thirteen known compounds, 6-methoxy-7,8-benzocoumarin (6), lapachenole, 8-methoxylapachenole, tectoquinone, 7-hydroxytectoquinone, dunniol, α-dunnione, dunnione, 8-hydroxydunnione, aggregatin E, cedrol, oleanolic acid, and halleridone, were also identified. 6-Methoxy-7,8-benzocoumarin (6) has been isolated for the first time from a natural source.
