以大黄素甲醚8氧葡萄糖苷为例探讨了利用HMBCNMR技术确定蒽醌苷类化合物结构中糖的连接位置的方法,在对其13CNMR谱进行全归属的同时,订正了文献中对结构中某些碳信号的错误指认.
Taking the method of HPLC for the determination of the attachment position of anthraquinones in anthraquinone glycosides, the emodin 8-glucoside glucoside was used as an example to study the 13CNMR spectrum of the anthocyanin glycosides. At the same time, Misidentification of some carbon signals.
