Hypericin 1 is present in plants, insects and protozoa. In plants, apart from H. perforatum, it occurs in a number of other species of Hypericum, namely H. hirsutum, H. maculatum, H. nummularium and H. triquetrifolium [17]. It is located in minute glands on different parts of the plants such as young stems, leaves and flowers. Interestingly, hypericin 1 is found in the integument of Australian Lac insects of the Coccoidea family, and appears with a number of structurally-related compounds [18, 19]. In protozoa, the blue-green ciliate, Stentor coerulus possesses a photoreceptor, stentorin, which consists of proteins bound to hypericin 1 [20].
