Hypericum perfuratum L. (St. John's wort) is one of medicinal plants belonging to Hypericaceae family [1], a perennial flowering plant, has nearly a 200-year history of use in traditional folk medicine for the treatment of various ailments [2]. The Pot experiments were carried out at the Researches Centre of Medicinal Plants & Ethno-veterinary, Shahrekord, Iran in 2011, to investigate the effect of the foliar application of jasmonic acid at the rates of 0.0 as a control, aceton as a solvent, 50, 100, 200 and 400µL on hypercin content of H. perfuratum L. The hypercin of the tetra-hydrofuran extract obtained from the areal parts of H. perfuratum by British pharmacopea. The result of analysis of variance of the experiment showed that different levels of the foliar application of jasmonic acid do have significant impacts on hypercin content. The, mean comparison by Duncan test showed that highest amount of hypercin was 200µL (0.8% hypericin/extract), and lowest amount of hypercin was aceton (0.8% hypericin/extract).
