Abstract

 Natural habitates of Iran content of more than 7500 plant species which many of them are medicinal plants. It is as the germplasm and could be source of supplying and producing of medicinal plant for cultivation. Hypericum perforatum growing naturally in the north and west of Iran. In these studies which have done in 1998 and 1999, samples of Hypericum perforatum at the flowering stage were collected from Gorgan, Nowshahr, Gilan in the north as the wetlands and Khalkhal in the west as the mountainous region. Hypericin as the secondary metabolite of Hypercicum perforatum were extracted by Soxhelt and measured by Spectrophotometer. Among the natural habitates, Gorgan and Gilan in 1998 with 2730 and 2584 PPM hypericin were significant with Nowshar anc Khalkhal respectively. Gilan, Gorgan and Nowshahr in 1999 with 2230, 2218 and 2120 PPM hypericin were significant with Khalkhal respectively. It seems hypericin production potential is high in regions with 250-400 m altitude and 500-900 mm rainfall and rich soil with organic and matter minerals.
