Selective Extraction of Embelin from Embelia ribes by Hydrotropes

Abstract

The research work proposes an alternate strategy of the extraction of embelin (2,5‐dihydroxy‐3‐undecyl‐p‐benzoquinone) from Embelia ribes. The aromatic hydrotropes such as sodium n butyl benzene sulfonate (NaNBBS), and sodium cumene sulfonate (NaCS) were found to be effective for the selective extraction of embelin with a recovery of 95% embelin from the aqueous solution of hydrotropes with high purity. The process was further optimized with respect to concentration of hydrotropes and temperature of extraction.
