This Study was carried out develop antitumor effect of the n-butanol soluble of fraction of Perilla frutescens on human skin melanoma cells. The antitumor activity of various fractions obtained form n-butanol soluble fraction of Perilla frutescens was evaluated in human skin melanoma cells. The antitumor activity of the n-butanol soluble fraction in human skin melanoma cells was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay, neutral red (NR) assay and sulforhordamine B protein (SRB) assay of colorimetic assay methods. The light microscopic study was carried out to observe morphological changes of cultured human skin melanoma cells. These results were obtained follows; The fractions 5 and 6 of the n-butanol soluble fraction of P frutescens were shown significant antitumor activities. The number of human skin melanoma cells were decreased and tend to form cell cluster by treatment with actions 5 and 7 of the n-butanol soluble fraction of P. frutescens. The fraction 6 of the the n-butanol soluble fraction showed the highest antitumor activity on P. frutescens. These results suggest that the fraction 6 of the n-butanol soluble fraction of P. frutescens may be a valuable choice for the studies on the treatment of human skin tumors.
