A semisynthetic route to produce hypericin was established using Cortex frangulae as the starting point.The emodin isolated from it easily and in good yield was reduced to emodin anthrone by means of SnCl2.The latter was reacted via a known oxidative dimerization and photocyclization reaction into hypericin. Keywords: Emodin; Emodin anthrone; Hypericin; Cortex frangulae.
