In the article titled “WS-5 Extract of Curcuma longa, Chaenomeles sinensis, and Zingiber officinale Contains Anti-AChE Compounds and Improves β-Amyloid-Induced Memory Impairment in Mice” [1], there was an error in Figure 4(a), where “DPPH inhibition activity (% of control)” should be corrected to “DPPH radical level (% of control).”

In addition, the authors wish to replace Figure 15 to show a modified possible underlying mechanism for WS-5.

Figure 4 

DPPH radical scavenging activity and TAS of WS-5. Inhibition of DPPH was measured using the radical scavenging assay (a), with vitamin C as positive control, along with the TAS assay (b). Results are expressed as the means ± SEM of three independent experiments (, , vs. control).

Schematic diagram showing possible underlying mechanism of WS-5.

The corrected Figures 4 and 15 are shown as follows.
