Mechanochemical solubilization and mechanochemically assisted extraction of plant bioactive substances

摘要

Mechanochemical solubilization and mechanochemically assisted extraction of plant bioactive compounds are discussed. The mechanochemical approach advances are illustrated by examples of some phytosterols, phytoecdysteroids and triterpenoid acids. The mechanical treatment of plant raw powder and solid reagents is used for chemical transformation of bioactive substance into soluble chemical form. In some cases it is possible to increase the extraction yield of bioactive substance more than 50%, to elevate the selectivity of green product and to simplify the following purification, to exclude the organic solvents from technology. Use of powder products of mechanochemical treatment as a commercial product is the most economically effective realization. Utilization of powder containing solubilized steroids and triterpenoid acids as growth regulator and results of biological tests are discussed.
