The bark of Lespedeza cyrtobotrya MIQ. afforded a new chalcone, lespeol (I), together with xanthoangelol (II).The heartwood of Lespedeza cyrtobotrya MIQ. afforded two new isoflav-3-ens, haginin A (IIIa) and B (IVa), together with genistein, daidzein, dalbergioidin, 3,9-dihydroxypterocarp-6a-en and isoliquiritigenin.The structures were established on the basis of chemical and spectral data. Keywords---Lespedeza cyrtobotrya MIQ.; lespeol; xanthoangelol; haginin A; haginin B; 3,9-dihydroxypterocarp-6a-en; genistein; daidzein; dalbergioidin; isoliquiritigenin
