Open publisher page 14 citations

Abstract

Hypericin, a photodynamic quinone, occurs in certain species of the genus Hypericum (the St. John's worts). Aspects of its photobiology and photochemistry, especially in relatin to its ability to generate singlet molecular oxygen, have been investigated. Its phototoxicity, including that towards Manduca sexta larvae, is also discussed.
