The Hemistepta lyrata Bunge flower has various biological and pharmacological effects, but effects of its absolute on skin regeneration or wound healing-linked responses remain unknown. In the present study, effects of Hemistepta lyrata Bunge flower absolute were explored on the proliferation and migration of normal human keratinocytes as well as the composition of absolute from Hemistepta lyrata Bunge flower was analysed using gas chromatography-mass spectrometry. Hemistepta lyrata Bunge flower absolute stimulated both proliferation and migration of the keratinocytes. It also enhanced the phosphorylation of extracellular signal-regulated kinase 1/2 and serine/threonine-specific protein kinase in human keratinocytes. Moreover, the Hemistepta lyrata Bunge flower absolute increased the sprout outgrowth of human keratinocytes. Gas chromatography-mass spectrometry analysis of Hemistepta lyrata Bunge flower absolute allowed identification of 16 compounds. These findings indicated that the absolute promoted the migration and proliferation of keratinocytes. Therefore, Hemistepta lyrata Bunge flower absolute might play a beneficial role in skin regeneration or wound healing by elevating migration and proliferation of keratinocytes.
