Molecular mechanisms of apoptosis in hepatocellular carcinoma cells induced by ethanol extracts of Solanum lyratum Thumb through the mitochondrial pathway

Table 2 Comparison of the inhibition rates of proliferation of hepatocellular carcinoma SMMC-7721 cells in the groups with different Solanum lyratum Thumb concentrations, ^-x ± s

Group	Concentration, mg/L	n	OD value	Inhibition rate, %
Three ST groups with different concentrations	2.5	12	1.516 ± 0.205	18.22 ± 2.32
	5	12	1.242 ± 0.236	36.56 ± 2.51
	10	12	0.815 ± 0.276	55.98 ± 3.12
Negative control group	0	12	1.842 ± 0.183	-
Positive control group	2.5	12	1.135 ± 0.172	38.60 ± 1.78

The comparison between ST groups and the negative control group shows that P < 0.05, while that of ST groups and the positive control group indicates that P > 0.05. ST: Solanum lyratum Thumb.
