title: Rotundines A-C, three novel sesquiterpene alkaloids from Cyperus rotundus.
abstract: Rotundines A (1), B (2), and C (3), three novel sesquiterpene alkaloids with an unprecedented carbon skeleton, were isolated from the rhizomes of Cyperus rotundus. The structures of 1-3 were elucidated by spectral and chemical methods.
