Four new lignans from the stems of Kadsura heteroclita.
Two new C(18) dibenzocyclooctadiene lignans named heteroclitalignans A and B (1 and 3), one new C(19) homolignan named heteroclitalignan C(4) and one new natural product named heteroclitalignan D(2), together with the four known lignans kadsurarin (5), kadsulignan E (6), d-epigalbacin, and meso-dihydroguaiaretic acid were isolated from the stems of Kadsura heteroclita. The structures of these compounds were characterized by extensive 1D and 2D NMR spectral data analysis.
