title: The cooccurrence of different biflavonoid types in Pilotrichella flexilis.
abstract: From Pilotrichella flexilis various flavonoids have been isolated. This species contains in contrast to P. cuspidata not only 3',3'''-binaringenin and related compounds, but also some hitherto unknown biflavonoids based on eriodictyol and aureusidin. The structures of two new compounds are elucidated spectroscopically. Possible causes for the differences of the flavonoid patterns between the two species of the genus Pilotrichella are discussed.
