Hypericin and hyperforin: bioactive components of St. John’s Wort (Hypericum perforatum) Their isolation, analysis and study of physiological effect
Hypericin a hyperforin: biologicky aktivní komponenty třezalky tečkované (Hypericum perforatum) Jejich izolace, analýza a studium fyziologických účinků
Třezalka (Hypericum perforatum L.) je tradičně využívaná léčivá rostlina v alternativní i klasické medicíně. V současnosti jsou k dispozici poznatky o fyziologické aktivitě jednotlivých sloučenin, které třezalka syntetizuje ve svých pletivech. Nejvyšší pozornost je věnována hypericinu a hyperforinu. Tyto organické sloučeniny nacházejí uplatnění v léčbě depresivních stavů, v protinádorové (fotodynamické) terapii a jako antimikrobiální a virostatické agens. V předkládaném souhrnu jsou ve stručnosti prezentovány současné poznatky o analýze, fyziologickém účinku a praktickém využití hypericinu a hyperforinu ve farmakochemii a biomedicínských oborech.
Klíčová slova:

Overview
#St. John’s Wort (Hypericum perforatum L.) is commonly accepted as a medicinal plant. The data on the physiological activities of the individual substances that are produced in different organs of H. perforatum are well known at present. The highest attention is focused on the characterization and phytochemical properties of hypericin and hyperforin. These organic compounds are used as antidepressant, anticarcinogenic (photodynamic), antimicrobial and virostatic agents. The review paper surveys the present knowledge of chemical and analytical methods for their identification and quantification, physiological activity, and pharmacological and biomedical applications of hypericin and hyperforin.
