摘要
Two new cyclic diarylheptanoids named ostryopsitrienol（1） and ostryopsitriol（2）,together with six known compounds,were isolated from the stems of endemic medicinal plant of Ostryopsis nobilis （Betulaceae）.The structures of the new compounds were elucidated by means of HRMS,~1D NMR,~2D NMR and X-ray crystallography analysis.
