title: Two New Secondary Metabolites from Tephrosia purpurea.
abstract: Further investigation of Tephrosia purpurea led to the isolation of a new prenylated flavone, isoglabratephrin B (1) and a new 1,2-ethanedione benzofuran derivative, purpdione B (2). The structures of the new isolates were elucidated on the basis of extensive spectroscopic analysis.
