摘要
The com pound bergenin w asisolated from theaerialpartsofBergenia pur- purascens. Allprotonsand carbons ofthe com pound w ereassigned and its structure w as char- acterized as 4-m ethoxy-2-[tetrahydro-3,4,5-trihydroxy-6-(hydroxym ethyl)pyran-2-yl]-α-re- sorcylic acid δ-lactone by using 1H-1H DQF-COSY, 1H-13CHMQCand HMBC. This w ork will be helpfulto the chem icalstructure studies ofthe sim ilar new ArylC-glycoside com pounds by m eans ofNMRspectroscopy.
