Antitumor Evaluation of Epigallocatechin Gallate by Colorimetric Methods

비색분석법에 의한 Epigallocatechin Gallate의 항암효과평가
Soon Ok Baek, Il Kwang Kim, Seung Hwa Baek, Du Seok Han

인체 피부흑색종 세포에 대한 epigallocatechin gallate의 세포독성작용을 평가하고, 광학현미경적 관찰을 실시하여 인체 피부흑색종 세포의 형태학적인 변화를 볼 수 있었다. 세포독성은 비색정량분석법, NR정량분석법과 SRB정량분석법으로 측정하였다. 이런 결과는 epigallocatechin gallate에 항암활성을 보여준다.

In the present study, we were evaluated cytotoxic effects of epigallocatechin gallate in human skin melanoma cells such as HTB-69. The light microscopic study showed morphological changes of the treated cells. Disruptions in cell organelles were determined by calorimetric methods; 3-(4,5-dimethyl thiazol-2-yl)-2,5diphenyl-2H-tetrazolium bromide (MTT) assay, neutral red (NR) assay and sulforhodamine B protein (SRB) assay. These results suggest that epigallocatechin gallate retains a potential antitumor activity.
