Figures & data

Figure 1. Half-maximal cytotoxic concentration (CC50) and half-maximal inhibitory concentration (IC50) of various R. stricta plant extracts against Vero E6 cells and SARS-CoV-2-infected Vero E6 cells, respectively. The graphs on the left (a, c, e and g) show the CC50 of various plant extracts. Vero E6 cells were treated with various concentrations of the extracts. Cell viability was examined by using a crystal violet assay. Absorbance was measured at λmax 570 nm. The graphs on the right (b, d, f, and h) show the IC50 against SARS-CoV-2 infected Vero E6 cells. The CC50 and IC50 values were calculated using non-linear regression analysis of GraphPad Prism.
