A novel flavanone glycoside has been isolated from the Chinese crude drug “mu tong” which is used in Hunan province, China. The structure of this new natural product is identified as 5,4′-dihydroxy-3′-methoxyflavanone-7-(6″-o-β-l-rhamnopyranosyl)-β-d-glucopyranoside by 1H, 13C NMR, COSY, 1H, 13C HETCOR, LOCOR and 1D NOE-difference spectra.
