Table 4.

Viability of BEAS-2B lung bronchus epithelial cells by different concentration of lotus leaves flavonoids (LLF) as evaluated by an MTT assay (n = 6)

Concentration (µg/mL)	OD₅₇₀	Viability inhibition rate (%)
0 (Control)	0.486 ± 0.006	/
125	0.473 ± 0.003^*	2.66 ± 1.45
250	0.465 ± 0.003^*	4.38 ± 1.49^#
500	0.445 ± 0.003^*	8.46 ± 1.26^##

Values presented are the mean ± standard deviation. Compared with the control group, the difference was significant (^*p < 0.05; ^**p < 0.01); and Compared with the 125 µg/mL LLF group, the difference was significant (^#p < 0.05; ^## p < 0.01)
