The study aimed to further evaluate the wound healing property of P. nigrum L. using bioassay-guided fractionation method. The ethanolic extract of Piper nigrum L. was fractionated in two stages using column chromatography and preparative reversed phase C18 HPLC, respectively. Significant wound healing properties screened using the scratch wound assay was observed through the cell migration assay in fraction number three (PNE3) out of the 14 fractions, exhibiting 36.7% and 43.8% closure of wound gap within 20 hours at concentration of 0.3 and 1.0 µg/mL, respectively. Sub-fractions which were further fractionated from PNE3 showed comparatively reduced wound healing activity using the same bioassay. The sub-fractions were also compared to Piperine, a major component of P. nigrum L. and the results were comparable. This experimental study revealed that Piperine works together with other compounds in P. nigrum L. to improve wound healing as claimed by those home remedy.
