摘　　要：应用２ＤＮＭＲ技术研究了土茯苓中两个新色原酮衍生物的结构，证实二维谱技术（ＣＯＬＯＣ，１Ｈ－１ＨＣＯＳＹ，２ＤＩＮＡＤＥＱＵＡＴＥ）可用于确定该类化合物的取代基位置．同时也有助于确定该类化合物的１３Ｃ、１ＨＮＭＲ谱的详细归属．The structures of two flavones, 5,7 dihydroxy chromone 3 0 α L rhamnoside(1) and 7,6' dihydroxy 3' methoxylisofavone (2), isolated from Smilax glabra were studied by 2D NMR spectra analyses. The attached positions of substituted groups in 1 and B ring of 2 can be determined by illustrating the COLOC and 1H 1H COSY spectra. All the proton and carbon signals of 1 were assigned in detail also.
