With agreement from the authors, the Editor-in-Chief retracts this article due to a misleading interpretation of the structure of an isolated compound.
This article dealt with the study of hydromethanolic extracts from 18 Algerian medicinal plants screened for their phenolic contents and radical scavenging activities. After careful study, the structure proposed for the active compound isolated from Cleome arabica appears to be not in agreement with the chemical shifts observed in the corresponding NMR spectra (Table 4). This proposed structure needs to be removed and will be fully amended elsewhere. Nevertheless, this does not undermine all the biological conclusions presented in the research article.
