Abstract

Two new isoflavone glycosides, ammopiptanosides A and B, have been isolated from the 95% EtOH extract of the twigs of Ammopiptanthus nanus (M.Pop.) Cheng f., together with six known compounds, and their structures were characterized by spectroscopic methods and compared with the data in the literature.

Keywords:
