摘　　要：从杜花科羊踯躅[Rhododendrom molle G.Don]果实中分得一个新的苷类化合物.经过测定,其结构是2′,4-二羟基-4′-甲氧基-6-O-β-D-吡喃葡萄糖-双氢查耳酮.本文主要讨论选择性远程DEPT和选择性NOESY新技术在该化合物的结构鉴别和NMR信号归属中的应用.A new aglycome compound was isolated from Rhododendrom molle G. Don and found to be asebotin. Selective long-range DEPT and selective NOESY techniques were used to determine its structure. Complete assignment of the ^1H and ^13C signals of the compound was obtained.
