The percentage of U373MG cells in the sub-G1 fraction after treatment with different doses of quercetin for 24 and 48 h.

Concentration (μM)	24 h	48 h
	Sub-G1 phase (%)	Sub-G1 phase (%)
Control	1.02 ± 0.35	0.5 ± 0.31
25	1.78 ± 0.89	1.71 ± 0.53
50	2.33 ± 1.17	2.26 ± 0.86
75	1.65 ± 0.65	6.66 ± 0.79a
100	2.05 ± 0.93	8.48 ± 0.40a

All data are the mean ± SD of three independent experiments. ^aSignificantly different from the control, P < 0.05.
