Özet

Wound is tissue damage that occurs in the skin. Helichrysum species (Altinotu) are rich in phenolic compounds used in traditional medicine for wound healing. The main component in their flower head (capitulum) is phenolic compounds. The present study investigates the proliferative, oxidative stress, and wound healing properties of the methanolic extract of Helichrysum plicatum subsp. pseudoplicatum capitulum on a human dermal fibroblast (HDF) cell line in this study. H plicatum subsp. pseudoplicatum capitulums were collected in Erzurum, Turkey (altitude 1950 m), dried, pulverized, and extracted with methanol. Firstly, total phenolic contents were determined and secondly, the proliferative effect, oxidative stress activities, and wound healing effects on HDF cells were evaluated by the cell proliferation kit (XTT) test, total antioxidant status (TAS), and total oxidant status (TOS) commercial kits, and the scratch experiment by taking microscopic images of the cells at 0, 12, 18, and 24 h, respectively. Total phenolic content was found to be 142.00 +/- 0.73 mg gallic acid equivalent per gram (GAE/g) extract. The capitulum extract has a proliferative effect at 0.5 to 10 mu g/mL concentrations according to the XTT test results. It was observed that TAS levels significantly increased in the plant extract at the concentration ranges 1 to 10 mu g/mL (P < .01). About 1 to 5 mu g/mL plant extract started to increase cell migration at the 12 h and significantly closed the wound area at the 24 h. At the doses between 1 to 5 mu g/mL, it has the most substantial effect on both cell viability and antioxidant effect, and wound healing was found to be in this concentration range. These findings suggested that the H plicatum subsp. pseudoplicatum capitulum is a valuable source of phenolic content with important antioxidant activity at wound healing and it was concluded that the capitulum extract accelerates wound healing by increasing cell migration in low doses.
