The special bandshape kinetic curve is essential to establish the method. Epinephrine is determined selectively by this method in. four catecholamine mixtures.展开更多
A new eudesmane sesquiterpene was isolated from the root of Rhaponticum uniflorum (Compositae) and Its structure was elucidated on the basis of spectra method (IR, EIMS, H-1-NMR, C-13-NMR, DEPT and H-1, H-1-Cosy) as 7...A new eudesmane sesquiterpene was isolated from the root of Rhaponticum uniflorum (Compositae) and Its structure was elucidated on the basis of spectra method (IR, EIMS, H-1-NMR, C-13-NMR, DEPT and H-1, H-1-Cosy) as 7 alpha, 8 alpha, 13-trihydroxy-eudesm-Delta 11(12)-diene.展开更多

It can remarkably catalyze the electrooxidation of catecholamine neurotransmitters. The electrocatalytic activity of DNA towards catecholamine neurotransmitters can be attributed to the interaction between DNA and the neurotransmitters.展开更多
