摘要：

Photoswitchable hydrotropic solubilization has been investigated by cis-trans isomerization about the olefinic bond of sodium cinnamate (Na-CIN) for various solutes such as cinnamic acid, aspartic acid, curcumin, thymol, and benzocaine. The extent and rate of isomerization depend on the concentration of Na-CIN and temperature. The cis-trans isomerization of Na-CIN by UV irradiation allows recovery of the solute from aqueous Na-CIN solutions, without dilution by water. Extraction of forskolin and curcumin from coleus forskholii and curcuma longa, was also studied for recovery under UV irradiation. (C) 2011 Elsevier B.V. All rights reserved.
