St. John's Wort. Molecular structure diagram for Hypericin (Chemical composition).

Surely this is missing the right-hand side? There cannot be two blind ended arms, there should be a methyl (CH3) group on each arm.

Towards a consensus structure of hypericin in solution: direct evidence for a single tautomer and different ionization states in protic and nonprotic solvents by the use of variable temperature gradient 1H NMR.
