title: Dioflorin, a Minor Flavonoid from Dioclea grandiflora
abstract: Dioflorin (1) was isolated as a minor constituent from the rootbark of Dioclea grandiflora, the crude extract of which demonstrated analgesic activity. The structure of 1 has been determined to be 5,7,2'-trihydroxy-8-methoxy-6-(3-methyl-2-butenyl)flavanone on the basis of spectral analysis.
