A Corrigendum on
Bioassay-Guided Interpretation of Antimicrobial Compounds in Kumu, a TCM Preparation From Picrasma quassioides’ Stem via UHPLC-Orbitrap-Ion Trap Mass Spectrometer Combined With Fragmentation and Retention Time Calculation

by Hu, H., Hu, C., Peng, J., Ghosh, A. K., Khan, A., Sun, D. and Luyten, W. (2021). Front. Pharmacol. 12:761751. doi: 10.3389/fphar.2021.761751

In the original article, there was a mistake in Table 3 as published. The IC50, and MBC calculations of positive controls were unintentionally incorrect when generated by software Graphpad, and may make people confused about their high IC50 values in the original manuscript. Hence, the tests of these compounds were repeated twice again to confirm these results. The corrected Table 3 appears below.

TABLE 3

TABLE 3. Antimicrobial activity (μg/ml) of three β-carbolines.
