SCE-AA mixture increases oxygen consumption rate (OCR) in hippocampal neuronal cells. (A,B), OCR of mHippoE-14 cells (2 × 104) incubated in Dulbecco’s Modified Eagle Medium (DMEM) containing Schisandra extract (SCE), ascorbic acid (AA), or an SCE and AA mixture (10 μg/mL) for 24 h was measured with an XF24 analyzer. (C,D), OCR following treatment with different ratios of SCE and AA was measured in mHippoE-14 cells. Area under the curve of basal OCR was calculated using XF24 software (B,D). Values are presented as means ± SD of triplicate samples (* p < 0.05 vs. corresponding control). CN, control.
