A Bibliometric approach for Analyzing the Potential Essential Oil Microemulsions

Abstract

Essential oils are bioactive compounds consisting of various pharmacological or therapeutic activities capable of causing changes in color and odor with unstable characteristics. Several studies have been conducted to overcome these problems by developing essential oil into microemulsion dosage forms. However, none have been conducted to identify the trends and patterns quantitatively through a collection of research publication documents. Therefore, this study identified the developments and areas of focus on essential oil microemulsions using bibliometric methods. Data was collected from PubMed from 2000 to 2021 and analyzed using R-studio and VOSviewer software. The results showed that 2020 had the largest number of publications, with 114 documents widely published in China. The most productive author, Oknologi S, used the keywords “Essential oils” and “microemulsions” 47 and 21 times, respectively. The trend of publications related to essential oil microemulsions is expected to increase with its continuous development.
