Chemical Content Variations of Hypericum perforatum Growing in Turkey during its Ontogenetic and Diurnal CyclesBy Dursun Kurt, Cüneyt Çırak
Abstract: AbstractThe biological activities of Hypericum perforatum have been mainly attributed to its hypericin and hyperforin contents. The present study was conducted to determine ontogenetic, morphogenetic and diurnal variation of hypericin, pseudohypericin and hyperforin contents in H. perforatum growing in Turkey. Plants were harvested at floral budding, full flowering, fresh fruiting and mature fruiting stages three times a day. When harvested they were dissected into stem, leaf and reproductive tissues, which …
