Photographic representation of wound closure on different post wounding days. A The morphological changes of polarity components wound at different time points. Wounds were marked with a ruler and photographed by a camera on day 3, 7, 9, and 11 after rat were modeled. B Effect of polarity components wound area ratio of each group at day 3, 7, 9, and 11 (Mean ± SEM). Negative control:carbomer; Positive control:rb-bFGF; PE: Petroleum ether-extract; CHCl3: Chloroform-extract; EA: Ethyl acetate-extract; n-butanol: n-butanol-extract. *p < 0.05 vs negative control group
