Abstract
Two new benzo[de]isoquinoline derivatives, 4-phenyl-benzo[de]isoquinoline-1,3-dione (1) and 4-(4-hydroxyphenyl)-benzo[de]isoquinoline-1,3-dione (2), were isolated from 70% ethanol extract of the rhizomes of Musa basjoo. Their chemical structures were elucidated by HRESIMS, 1 D and 2 D spectra.
