L., family Hypericaceae. Hypericum contains flavonoids, xanthones, naphthodianthrones such as hypericin and pseudohypericin and phloroglucinols, e.g. hyperforin. Hypericin has anti-HIV activity and is responsible for the photosensitivity reaction which has been documented for St. John s Wort in cattle and...

In contrast to corresponding flavones, only a few structures are reported with a pyrano-substitution, mostly of the chromeno-type between the 7-OH and the neighboring C-8. Major sources are roots, aerial parts, and leaves from Rutaceae, Moraceae, and Fabaceae. The earlier reported Asclepias syriaca (Asclepiadaceae) affords a rare source of such structures. So far, the corresponding 7,6-chromeno structures (sarothranol) are known only from whole plants of Hypericum japonicum (Hypericaceae). ...

Binapthoquinones include the phototoxic phytotoxin cercosporin from the fungus Cercospora (two Phe Q moieties linked by two Phe—Phe links and an MD link). Hypericin (two anthraquinones linked by three Phe—Phe linkages) is a bianthraquinone from Hypericum species (Hypericaceae). Hypericin is a phototoxic protein kinase inhibitor that causes light-dependent ovine facial eczema. Benzonaphthoquinones include the der-matitic cypripedin (Phe Phe QJ. Lichen 7-chloroemodin is a novel chloroanthraquinone and the fused tricyclic pyrano-a-naphthoquinone (3-lapachone (Phe oQJ C50) is a reverse transcriptase inhibitor with antimicrobial and cytotoxic activity.

PCS-catalyzed condensation of five molecules of malonyl-CoA to produce 5,7-dihydroxy-2-methyl chromone new to this plant (40). Another novel Aloe arborescens type III PKS that produces two hitherto unknown aromatic octaketides, SEK4 and SEK4b, has recently been reported (41). The application of plant cell cultures for the production of the polyketide hypericin from St. John s wort (Hypericum performatum, Hypericaceae) has been investigated (42).
