摘要
应用 2DNMR实验技术进一步研究确定了从百合科植物大叶吊兰中分离到的两个新的C 2 7甾体皂甙类化合物 ,大叶吊兰甙 (chloromaloside)A和B的化学结构 ,并对其1 H和1 3CNMR信号进行了全归属 .
By means of 2D NMR techniques, such as HMQC TOCSY,TOCSY,ROESY,HMQC,HMBC and COSY, the structures of chloromaloside A and B, two new C 27 steroidal saponins from \%Chlorophytum malayense\% were confirmed. Their complete assignment of \{\}\+1H and \{\}\+\{13\}C NMR chemical shifts were also obtained. \;
