The antiproliferative effects of 1–13 from C. alba. Each compound was treated at the concentration of 50 μM into androgen-dependent prostate tumor LNCaP, androgen-independent prostate tumor DU145 and normal prostate epithelial RWPE-1 cells. The results were expressed as mean ± S.D. of triplicated experiments. **: p < 0.01, ***: p < 0.001, compare with LNCaP Blank group; #: p < 0.05, ##: p < 0.01, ###: p < 0.001, compare with RWPE-1 Blank group; @: p < 0.05, @@: p < 0.01, @@@: p < 0.001, compare with LNCaP Blank group.
