The structural determination of two compounds viz., nitiducarpin and dalbergin which are isolated from the benzene and chloroform extract of the stem of Dalbergia rubiginosa is discussed in detail. The structures of these compounds are established from the colour reaction, UV, IR, 1H NMR and 13C NMR spectra. In case of dalbergin, the structure is confirmed by preparing the acetate, recording their spectra and comparing the values with the literature values. The structures of nitiducarpin and dalbergin are confirmed by comparison with an authentic sample also.
