The authors would like to make corrections to their published paper . There were mistakes in some usages of the chemical name “isoplumbagin” in the original version in Sections 2.1, 3.1, and 3.2. These “isoplumbagin” words should be changed to “plumbagin”. Literature reported that the difference between plumbagin and isoplumbagin is the coupling constant of methyl group (1.5 Hz for plumbagin and 1.2 Hz for isoplumbagin) . We found that the 1H and 13C spectra data (Figures 1 and 2) of the main compound of EANT is plumbagin because our compound shows a J value of 1.5. Therefore, we confirmed the major compound of EANT to be “plumbagin” based on spectra data rather than isoplumbagin.
