Yf. Chen et al., ISOLATION AND STRUCTURE OF CLEMATINE, A NEW FLAVANONE GLYCOSIDE FROM CLEMATIS-ARMANDII FRANCH, Tetrahedron, 49(23), 1993, pp. 5169-5176
A novel flavanone glycoside has been isolated from the Chinese crude d
rug ''mu tong'' which is used in Hunan province, China. The structure
of this new natural product is identified as '-O-beta-L-rhamnopyranosy
l)-beta-D-glucopyranoside by H-1, C-13 NMR, COSY, H-1, C-13 HETCOR, LO
COR and 1D NOE-difference spectra.
