Figure 2
Average IC 50 (μg/ml) values of the eight fractions, obtained after quick column chromatography, on the five cancer and two normal cell lines. 100HEX, 10DCM, 30DCM, 50DCM, 70DCM, 100DCM, 5MET and 10MET stand for the fractions eluted in 0:1, 1:9, 3:7, 1:1, 7:3 and 1:0 (v/v) ratios of CH2Cl2: hexane, and 1:19 and 1:9 (v/v) ratios of MeOH: CH2Cl2, respectively (see table 3). Data came from the mean ± 1 SD of percentage of cell viability which was derived from three replicates.
