Hydrotropic solubilization of total boswellic acids fromBoswellia serrata gum resins has been investigated
with aqueous solutions of alkylbenzene sulfonate hydrotropes. Due to their amphiphilic structures, the
hydrotropes cooperatively form microassemblies in aqueous solutions which, in turn, are responsible for
the solubilization of water-insoluble organic substances. The solubility of boswellic acids was increased
by 2 orders of magnitude in the presence of hydrotropes in aqueous solutions. The effect of hydrotrope
concentration on the solubility was investigated in detail along with the kinetics of solubilization. The
selectivity toward boswellic acids over other terpene compounds was investigated by molecular modeling
using the AMBER94 force field
