Polyphenols in Ilex latifolia Thunb. inhibit human lung cancer cell line A549 by regulation of the PI3K-Akt signaling pathway

Table 2 Inhibitory effect of different concentrations of ILTPs on proliferation of A549 lung cancer cells (n=6)

Group	OD₄₉₀ (Concentration of ILTPs, μg/mL)			Cell growth inhibition rate (%)
Group	125	250	500	125	250	500
Control	0.445±0.005^a			/
ILTPs	0.320±0.011^b	0.204±0.007^c	0.059±0.005^d	28.10±2.51^C	54.16±2.02^B	86.74±1.76^A

The experimental results are mean ± 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), the same letter indicates that there is no significant difference in the average value of each group (P > 0.05)
