伞形花内酯

In this work, the interaction between umbelliferone and bovine serum albumin was studied by performing two different kinds of titration modes. The two spectroscopic data matrices were augmented, and then the information of experiment data was increased. The augmented experiment data matrix was analyzed by the MCR-ALS method. This procedure allowed the recovery of the concentration profiles for each species and the calculation of the ∶ ratio in the complex and the apparent equilibrium constant.
