| Abstract: | 1H and 13C NMR spectra of polysubstituted xanthones and corresponding xanthone-O-glycoside, which are obtained from the plants of Qinghai-Xizang plateau,have been observed.The discussion are mainly focused on the relation between the chemical shifts and mode of substituted groups on 1,8 position of polysubstituted xanthone.1H chemical shifts of substituted hydroxy on 1,8 position of xanthone have been summarised.The changes of chemical shift of carbon on xanthone ring caused by -O-sugar have been calculated and discussed.The result can be used to elucidate the structure of polysubstituted xanthone and xanthone-O-glycoslde. |
