Abstract
The fruits of Morus alba L. were extracted with 80 % aqueous MeOH, and the concentrated extract was partitioned into EtOAc, n-butyl alcohol, and water fractions. The repeated silica gel ($SiO_2$) and octadecyl silica gel column chromatographies for the EtOAc and n-butyl alcohol fractions led to isolation of two phenolic compounds. The chemical structures of the compounds were determined as Diels-Alder type adducts, mulberrofuran E (1) and chalcomoracin (2) based on spectroscopic data analyses including nuclear magnetic resonance, mass spectrometry, and infrared spectrometry. Compounds 1 and 2 were isolated for the first time from the fruits of M. alba L. in this study.
