Figure 3

Correlation Analyses. IC50 values were evaluated by linear regression analysis. Correlation coefficients between cytotoxic activity and Chl/chlide contents were calculated by Pearson’s correlation coefficient and showed here. High correlation: 0.7-0.99 (correlation coefficients); moderate correlation: 0.4-0.69; modest correlation: 0.1-0.39; weak correlation: 0.01-0.09.
