| Abstract: | The ~1HNMR spectra of berberine,berberine chloride and berberine hydroxide are studied.The effect of D_2O on solvent porlarization shiclding in DMSO-d_6 is investigated.It turns out that the peaks of those protons adjaecnt to the molecular dipolar center shifi to high field on both salt forming and H-D exchanging. |
