title: Structural identification of an anthrasteroid hydrocarbon from the sheep tick Ixodes ricinus.
abstract: A new anthrasteroid hydrocarbon was isolated from cuticular integument of engorged female Ixodes ricinus, and its structure was determined by interpretation of spectroscopic and nuclear magnetic resonance data as 14alpha(H)-1(10-->6)-abeo-cholesta-3,5,7,9(10)-tetraene (1).
