Abstract
The aerial parts of Lespedeza cuneata were collected, air-dried and extracted with 95% aqueous EtOH. Then it was successively partitioned with n-hexane, $CH_2Cl_2$, EtOAc and $H_2O$. Repeated Sephadex LH-20 column chromatography on the EtOAc- and $H_2O-soluble$ fractions gave four compounds. Their structures were elucidated as quercetin (1), kaempferol (2), desmodin (3) and homoadonivernith (4) on the basis of spectroscopic evidences such as $^{1}H-NMR$, $^{13}C-NMR$, 2D-NMR and MS spectrum. Desmodin (3) and homoadonivernith (4) have not been reported from this plant so far.
