title: Tetrahydrofuran lignans from Viburnum betulifolium.
abstract: A phytochemical investigation of the EtOH extract from the aerial parts of Viburnum betulifolium Batal. afforded four new tetrahydrofuran lignans, betulifolium A-D (1, 2, 4, and 5), together with two known compounds vibsanol-9'-al (3) and sarcomeginal (6). This paper deals with the isolation and structure elucidation of the new compounds on the basis of spectroscopic methods, including 1D NMR, 2D NMR analyses and HR-ESI-MS data.
