Correction: Linear Quantitative Profiling Method Fast Monitors Alkaloids of Sophora Flavescens that was Verified by Tri-marker Analyses

In “The Linear Quantitative Profiling Method” section, there is an error in the first equation. Please see the complete, correct equation here:

$$\mathit{r}=\frac{{\sum }_{i=1}^n(x_i-\overline{x})(y_i-\overline{y})}{\sqrt{{\sum }_{i=1}^n{(x_i-\overline{x})}^2}\sqrt{{\sum }_{i=1}^n{(y_i-\overline{y})}^2}}$$

In “The Linear Quantitative Profiling Method” section, there is an error in the second equation. Please see the complete, correct equation here:

$$\mathit{b}=\frac{n{\sum }_{i=1}^n{x}_i{y}_i-{\sum }_{i=1}^n{x}_i{\sum }_{i=1}^n{y}_i}{n{\sum }_{i=1}^n{y}_i^2-{\left({\sum }_{i=1}^n{y}_i\right)}^2}\times \frac{m_R}{m_j}\times 100\mathrm{\%}\approx \frac{\overline{x}}{\overline{y}}\times \frac{m_R}{m_j}\times 100\mathrm{\%}=\mathit{R}\times \frac{m_R}{m_j}\times 100\mathrm{\%}$$
