Artocarpus lowii, prenylated chalconesAbstract
Two minor prenylated chalcones were isolated for the first time from the leaves of Artocarpus lowii King. These prenylated chalcones were identified as 2-hydroxyparatocarpin C (1) and 2¢,3,4¢,4-tetrahydroxy-3¢-prenylchalcone (2). The structures of these prenylated chalcone were elucidated by utilizing the data values obtained from 1H NMR, 13C NMR, DEPT, COSY, IR, UV and MS, as well as by comparison with literature values. Â
