Abstract: | The present study was conducted to determine the total hypericin contents of Hypericum triquetrifolium Turra. and Hypericum scabrum L. species
which are naturally distributed in the flora of Siirt province, Turkey. Hypericin
contents of Hypericum species grown in different geographical aspects (North,
South, East, and West), and it was measured at different harvest times (full blooming and post blooming period). In the current study, it has been determined that
total hypericin content varies considerably according to aspects, plant developmental stages (ontogenetic variance), and species. According to species x aspect
interaction, the highest total hypericin content was recorded from the west aspect
(3.13 mg/g) in Hypericum triquetrifolium, while, the lowest hypericin content was
also obtained from the west aspect (1.22 mg/g) in Hypericum scabrum. When the
highest total hypericin content was analyzed according to aspect x species x harvest time interaction, the highest total hypericin content was produced from
Hypericum triquetrifolium at the harvest of west aspect with 5.28 mg/g, while
the minimum amount of hypericin was obtained from the same aspect in Hypericum scabrum with 0.50 mg/g. In species x harvest time interaction, the highest
total hypericin content was obtained from the full bloom (3.10 mg/g) harvest in
Hypericum triquetrifolium, while the lowest hypericin was obtained from the full
bloom (1.26 mg/g) harvest in Hypericum scabrum. The data suggest that the average total hypericin content was 2.26 mg/g in Hypericum triquetrifolium and
1.28 mg/g in Hypericum scabrum. |
