Isolation and Identification of Active Ingredients from Plants by Complexation Method

摘要

A new method (complexation method) for the isolation of active ingredients of plants having ligand properties has been proposed and used successfully for isolation of nicotine from tobacco. The method was used for isolation of medicinally important components of Perovskia abrotanoides, an indigenous medicinal plant. Complete isolation of single components was not achieved. However, the plant extract which contained dozens of compounds was reduced to 3-4 components. Complexation method as compared with other methods of isolation is quite easy, quick, and less expensive.
