title: Asterogynins: secondary metabolites from a Costa Rican endophytic fungus.
abstract: An endophytic fungus isolated from the small palm Asterogyne martiana produced two unusual steroid-like metabolites, asterogynin A (1) and asterogynin B (2), along with the known compounds viridiol (3) and viridin (4). Asterogynins A and B were characterized by NMR and MS spectroscopic analysis.
