At the authors request, the Editor and Publisher of Drug Design, Development and Therapy wish to retract the published article. The authors informed the journal when attempting to scale up salvianolic acid microcapsule development, using the same process described in the article, they were unable to replicate the results previously reported. The previous study was based on small laboratory trials and preliminary analysis with no instability of the salvianolic acid B observed. However, during the process of scaling up the study the authors observed considerable instability of salvianolic acid B indicating the process design is unreliable and the findings reported previously are invalid. In addition, the authors were also unable to locate the raw data for their original study. The Editor agrees with the decision to retract the paper.
Our decision-making was informed by our policy on publishing ethics and integrity and the COPE guidelines on retraction.
The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as “Retracted”.
