Abstract
Correction for ‘Structural modification of olibergin A, an isoflavonoid, from Dalbergia stipulacea Roxb. and its cytotoxicity’ by Supakorn Arthan et al., RSC Adv., 2022, 12, 17837–17845, https://doi.org/10.1039/D2RA02865D.
The authors regret that incorrect IUPAC nomenclature was used for compound 4 in the manuscript. The correct nomenclature for compound 4 is “5-hydroxy-2′,5′-dimethoxyisoflavone 7,4′-dipentanoate”.
In addition, for compound 3, the spectroscopic data contains the phrase “cmb:b:line” for the two signals at 168.8 and 168 ppm. The correct spectroscopic data for compound 3 is “168.8 (MeCOO-7), 168.0 (MeCOO-4′)”.
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
