The Study of Steaming Durations and Temperatures on the Chemical Characterization, Neuroprotective, and Antioxidant Activities of Panax notoginseng
Figure 4
Protective effect of raw and steamed Panax notoginseng (PN) extracts suppressed Aβ1-42-induced cell viability loss in PC12 cells. (a) Cells were treated with Aβ1-42 at the indicated concentrations (1, 5, and 10 μM) for 24 h and cell viabilities were assessed by MTT assay. (b) Cells were treated with Aβ1-42 (5 μM) and co-incubated with raw or steamed PN extracts (100 μg/mL) for 24 h and cell viabilities were assessed by MTT assay. Huperzine A (HA, 10 μM) was served as positive control. versus vehicle control group or Aβ1-42-induced model group as indicated, #, ##, ### versus the raw PN treated group were considered statistically significant differences.
