Figure 5: A comparison of the hair growth promoting potential of n-butanol-n4 fraction extract in vivo. (a) The n-butanol-n4 fraction (3%, w/v) ((E), (J), and (O)) was administrated to telogenic mice to compare its hair growth promoting potential with the n-butanol (3%, w/v) ((C), (H), and (M)) and DW (3%, w/v) ((D), (I), and (N)) extracts. MXD (3%, w/v) was used as the positive control ((B), (G), and (L)) and 40% ethanol was used as the negative control ((A), (F), and (K)). The dorsal skin area () was photographed at 0 days, 10 days, and 14 days after treatment. (b) The anagenic areas (complete black area) 14 days after treatment were calculated by using the Image J processing program. The data are presented as the means ± SD () and the different letters in (b) indicate significant differences () between the groups.
