Matrine trypsin inhibitory activity than matrine trypsin inhibitory activity than daidzein trypsin inhibitory activity than genistin trypsin inhibitory activity. Daidzin and genistin trypsin inhibitory activity is very low. Matrine trypsin inhibitory activity was higher, up to 53.95%. When macromolecules with small molecules matrine trypsin molar ratio of 1: 2, the inhibition rate no longer increased significantly. This matrine with trypsin molar ratio of 2: 1 with the largest UV difference spectra, above this molar ratio, trypsin absorption peak near 280 nm absorption value of no obvious change of the experimental phenomena are basically the same . May be at this time the interaction of matrine and trypsin is nearing saturation, no change in secondary structure has been further confirmed speculation. Matrine trypsin inhibitory activity lower than matrine, when the trypsin-macromolecules and small molecules Oxymatrine molar ratio of 1:5, the inhibition rate reached 45.39%. Matrine trypsin inhibitory rate increased with the increase of the concentration, trypsin and the molar ratio of matrine from 1:1 to 1:2 up to inhibition rate, the increase is more obvious and the molar ratio of from 1:2 to 1:5 to curb the rate of change in more gently.

| This experimental phenomena is basically the same when the molar ratio of matrine and trypsin is 2:1. At this ratio, the UV spectra difference is the largest. While, the trypsin absorption value around absorption peak near 280 nm has no obvious change with higher ratio. |
