The current study was undertaken to determine the effects of UV-C radiation of total hypericin, phenolic and flavonoid content in Hypericum triquetrifolium Turra. The UV-C radiation was applied to H. triquetrifolium at different periods (15, 30, 45, 60 min). The highest total hypericin, phenolic and flavonoid accumulation 292 +/- 2.8, 357 +/- 3.4 and 331 +/- 3.7 mu gg(-1) was achieved in 15 minutes of exposure to UV-C radiation when compared with the contents of control groups (140 +/- 2.3, 185 +/- 3.7, 173 +/- 2.5 mu gg(-1)). |
