title: [Studies on chemical constituents of Astragalus complanatus R. BR].
abstract: Sha-Yuan-Zi is the seeds of Astragalus complanatus R. Br.. Eight compounds were isolated from its 80% ethanolic extract. Their structures have been identified by spectroscopic and chemical methods. Two of them are new and named neocomplanoside (VII) and myricomplanoside-(VIII) respectively. All the compounds were obtained from Sha-Yuan-Zi for the first time.
