AIM: To study the chemical constituents of Peristrophe roxburghiana . METHODS: The aerial parts of Peristrophe roxburghiana were extracted with EtOH and isolated by LC, the structures were determined by UV, IR, NMR and MS. RESULTS: Two compounds were identified as 5,6 dimethoxy 2(3H) benzoxazolone(I) and 2 amino 7,8 dimethoxy 3H phenoxazine 3 one(II) respectively. CONCLUSION: Two chemical constituents obtained were new compounds and named peristrophamide(I) and peristrophine(II).
