An efficient method based on an inhibitor-enzyme complex to screen an active compound against lipase from .

As a popular vegetable, has a wide range of bioactivities including lipase inhibitory activity. In the present study, an efficient and rapid method using a ligand-enzyme complex was established for screening of an active compound against lipase from . The ethyl acetate extract of showed good lipase inhibitory activity.

Rapid screening and separation of active compounds against α-amylase from Toona sinensis by ligand fishing and high-speed counter-current chromatography.

In the present study, an efficient method based on ligand fishing and high-speed counter-current chromatography (HSCCC) was established to screen, enrich and separate the active components with the α-amylase inhibitory activity from a traditional dish Toona sinensis. The active components were screened from T. sinensis by ligand fishing using the magnetic immobilized α-amylase prepared through solvothermal and crosslinking methods.
