Inhibitory effect of different concentrations of flavonoids from lotus leaf (LLEFE) on the proliferation of HT-29 human colon cancer cells.

Group	OD490 (concentration of LLPs, μg/mL)			Cell growth inhibition rate (%)
	125	250	500	125	250	500
Control	0.493 ± 0.006a			/
LLEFE	0.357 ± 0.010b	0.211 ± 0.005c	0.063 ± 0.004d	27.59 ± 2.32C	57.10 ± 1.00B	87.20 ± 0.81A

The experimental results are average ± standard deviation. Duncan multiple range test showed that ^a–d and ^A–C of different letters showed significant difference in the mean value of each group (P < 0.05).
