Effects of crude extract and solvent fractions of R. anthopogonoides on cell viability in hypoxia-injuried PC12 cell. PC12 cells are pre-incubated with EEF or BuF (50–200 μg/ml) for 1 h prior to hypoxia for 24 h. After the treatment, cell viability is determined by MTT analysis. Data are shown as means ± SD (n = 6). ##p < 0.01 vs. control.* p < 0.05 vs. hypoxia, **p < 0.01 vs. hypoxia. CE: crude extract, HF: n-hexane fraction, EEF: ethyl acetate fraction, BuF: n-butanol fraction, WE: water fraction, Vc: ascorbic acid. Rutin is used as positive control
