Wound healing activity of Streptocaulon juventas root ethanolic extract

ABSTRACT

Streptocaulon juventas is a well-known plant that has antimicrobial activity, in vitro antiplasmodial activity, anti-proliferative activity, and antioxidant activity. In this study, we showed experimental evidence that proved that Streptocaulon juventas root ethanolic extract has wound healing activities. First, in a mouse excision wound model, Streptocaulon juventas root ethanolic extract at a dose of 100 mg/kg/day significantly reduced the wound closure time. After 7 days, the wound granulation tissue in mice treated with the extract exhibited a 2.3-fold decrease in inflammatory cells, a 1.7-fold increase in fibroblasts and enhanced angiogenesis. Molecular analysis also revealed that after wounds were treated with Streptocaulon juventas root ethanolic extract, TNF-α and NF-κB1 gene expression were down-regulated by 4.7 and 3.7 times, respectively. In contrast, TGF-β1 and VEGF gene expression were up-regulated by 1.9 and 6.5 times, respectively. Taken together, our experimental data strongly demonstrate that the ethanolic extract from Streptocaulon juventas root displays remarkable wound healing activity.
