Renealtins A and B, new diarylheptanoids with a tetrahydrofuran ring from the seeds of Renealmia exaltata.
Two new diarylheptanoids, renealtins A (1) and B (2), have been isolated from the seeds of the Brazilian medicinal plant Renealmia exaltata ("Pacová-catinga", Zingiberaceae), and their structures were elucidated by spectroscopic data. Renealtins A (1) and B (2) are the first example of naturally occurring diarylheptanoids containing a tetrahydrofuran ring.
