Chemical Constitution of St. John's Wort Powder Extract
Hypericins, which are the most important ingredients in St. John's Wort Powder Extract that are studied by lots of scientists all over the world. St. John's Wort contains protohypericin, protopseudohypericin and cyclopseudohypericin. All these occur mainly in the flowering parts of the plant and especially located in the dark glands. Protohypericin and protopseudohypericin are considered to be the biosynthetic precursors of hypericin and pseudohypericin, respectively, from which the latter derive on exposure to light. Also pseudohypericin is likely to be transformed to cyclopseudohypericin. Protohypericin, protopseudohypericin and cyclopseudohypericin are detected in lower concentrations and are included in the analytical term “total hypericins” or “total naphthodianthrones”. In general, the content of pseudohyhypericin (0.03–0.34%) is higher from that of hypericin (0.03–0.09%) two to four times, depending on the variety.
