Two new neolignan glycosides, davidioside A (1) and davidioside B (2), have been isolated along with six known compounds from the branch bark of Davidia involucrata. Identification of their structures was achieved by 1D and 2D NMR experiments, including (1)H-(1)H COSY, NOESY, HMQC, and HMBC methods as well as FAB mass spectral data.
