摘要: 应用2D NMR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-1H COSY,2D INADEQUATE)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、1H NMR谱的详细归属.

Abstract: 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.

Key words: Smilax glabra, Chromone, Isoflavone, 2D NMR, COLOC
