The effects of the TC extracts on the nitrite production and cell survival rate in the RAW264.7

Treatment Cell viability (%) Nitrite production (μM) Nitrite / Cell viability
Vehicle 100 ± 1.24d 250 ± 0.16a 33.28 ± 0.41a
LPS + Vehicle 101.54 ± 4.39d 16.96 ± 0.26h 98.63 ± 416f
LPS + TCEE 150μg/ml 111.89 ± 1.89e 7.40 ± 0.26c 59.63 ± 2.93b
LPS + TCEAE 150 μg/ml 102.00 ± 1.95d 8.46 ± 0.26d 45.44 ± 1.31d
LPS + TCBUE 250 μg/ml 119.78 ± 1.21e 5.71 ± 1.04b 50.55 ± 4.12c
LPS + TCWE 400 μg/ml 101.01 ± 1.59d 9.88 ± 0.46e 66.72 ± 3.92e
LPS + Dexamethasone 1 μM 110.20 ± 5.26e 5.41 ± 0.20b 42.43 ± 2.09b

Values are the mean ± SD (n = 5) and were analyzed using one-way ANOVA followed by Duncan’s new multiple range test. Dexamethasone (1 μM) is the positive control and cells were treated with 100 ng/ml LPS to induce inflammation.
