| Abstract: | A systematical research is made on the chemical shift data,of natural purine alkaloid￣(13)C-NMR us-ing a mathematical model. It shows that the chemical shift has good additity and degradativity to the incre-ments of undisplaced parent.The C-NMR chemical shift of some unknown substances is predicted. |
