In this study, we evaluated the anti-cancer property of five bark extracts and the isolates from chloroform and ethyl acetate of Annickia chlorantha by the tetrazolium salt method (MTT method). The anti-cancer activity was performed on human prostate cancer cell lines PC-3 and hormone-dependent breast cancer cell lines MCF-7. Results indicated that the two isolates displayed interesting cytotoxicity towards MCF-7 cell lines with CC 50 of 3.84 CC 50 /mL and 4.87 CC 50 /mL for chloroform and ethyl acetate respectively; while the total bark extracts showed CC 50 of 24.33 CC 50 /mL, 36.49 CC 50 / mL and 73.52 CC 50 /mL for chloroform, ethyl acetate and methanol extracts respectively. By the other hand on PC-3, the CC 50 of the isolates were higher than the one on MCF-7, more than 10 CC 50 /mL for both chloroform and ethyl acetate isolates and 49.14 CC 50 /mL, 77.33 CC 50 /mL, 89.38 CC 50 /mL and 92.37 CC 50 /mL, respectively for chloroform, ethyl acetate and methanol soluble extracts. From this study, we identified that the two isolates had anti-cancer properties against MCF-7 cell lines.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
