AI Article Synopsis
- Seedlings of Hypericum perforatum were grown with chromium concentrations of 0.01 and 0.1 mM in nutrient media.
- Treatment with 0.01 mM Cr(VI) for seven days led to increased productions of protopseudohypericin (+135%), hypericin (+38%), and pseudohypericin (+5%), while 0.1 mM Cr(VI) treatment for two days also showed significant increases.
- The most notable results were seen at 0.1 mM Cr(VI) for seven days, with protopseudohypericin increasing by +404% and pseudohypericin by +379%, though hypericin levels remained unaffected.
Article Abstract
Seedlings of Hypericum perforatum were grown with 0.01 and 0.1 mM of chromium added to the nutrient media. A treatment with 0.01 mM Cr(VI) for seven days resulted in an increased production of protopseudohypericin (+135%), hypericin (+38%) and pseudohypericin (+5%). Treatment with 0.1 mM Cr(VI) for two days also caused an increase of protopseudohypericin (+167%), hypericin (25%) and pseudohypericin (+5%). The greatest effect of chromium treatment was observed at a concentration of 0.1 mM for seven days: protopseudohypericin increased +404% and pseudohypericin to +379%. Hypericin was not affected by this treatment.
