From the aerial parts ofTylopbora indica, five new dihydrophenanthroindoli-zidine alkaloids, tyloindicines F [2], G [3], H [4], 1 [5], and J [6], and a benzcyclopent-substi-tuted phenanthrene derivative, tyloindane [1], have been isolated along with tylophorine. The structures have been determined by analysis of spectral data and chemical reactions. © 1991, American Chemical Society. All rights reserved.
