【Abstract】 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. \;更多还原
