Novel insight into wound healing properties of methanol extract of Capparis ovata Desf. var. palaestina Zohary fruits
Özet
ObjectivesThe objective of this study was to investigate the wound healing activity of Capparis ovata var. palaestina fruit extract in mice. For this aim, wound healing, invitro antimicrobial and antioxidant activities, HPLC, phenolic and flavonoid compounds analyses were performed. MethodsThe wound healing effect was tested by excisional wound model. Wound closure was measured for 14days and at 14th day wound healing was assessed by levels of TGF-, VEGF, COL1A1 and angiogenesis, granulation tissue thickness, epidermal and dermal regeneration. The antioxidant activity was calculated by DPPH and ABTS free radical scavenging assays. Antimicrobial ability was evaluated by minimum inhibitory concentration and agar well diffusion tests. Key findingsThe extract indicated significant antioxidant activity while it also exhibited antimicrobial activity. Rutin was found in the extract according to HPLC study. Moreover, the extract was found to have rich phenolic and flavonoid contents. Histological evaluation showed that extract group induced significant (P<0.001) wound healing activity compared to control group. Furthermore, extract group increased wound healing rates by promoting granulation tissue, epidermal regeneration, angiogenesis, collagen, TGF- and VEGF. ConclusionsThe results clarified that the extract possesses antioxidant, antimicrobial activity and thus could provide a valuable contribution to the wound healing.
