title: Aristophenones A and B. A new tautomeric pair of polyisoprenylated benzophenones from Garcinia aristata.
abstract: A tautomeric pair of new isoprenylated benzophenones, aristophenone A (1a) and B (1b), have been isolated from Garcinia aristata fruits. Their structures has been determined using high-field 2D NMR techniques.
